@@EarthquakeSim it was wonderful! A little quick, but I really enjoyed seeing the Town comparison slightly more than the Grocery store. Do you do Tsunami comparisons?
I feel like it’s important to mention, especially for those who don’t know, in earthquake prone areas, buildings are made to be able to sway a bit with the earthquake, so the building swaying as the earthquake is happening is actually normal and realistic in the simulation.
it’s to be able to handle the pressure and energy of the earthquake. in japan they are doing this with their sky scrapers and similar buildings, to avoid the likeliness of falling down. TL ; DR to go with the flow of energy built up by the earth quake and not fall down.
I think it's really impressive for the shelves to stay mostly undamaged and upright for anything less than a gigantic asteroid strike.Someone should build the store as sturdy as these shelves.
Yeah i was like expecting the shelves to be thrown around and flying or something but i guess i underestimated how heavy they were and the roofs collapsing jumpscared me
they are not bolted to the floor in most cases imo. think about how often stores do a remodel or rearrange things. when they remodeled the store i worked at they basically got a little jack thing and some sliders and lifted the whole thing up and just slid the shelves around, product on it and everything. so in this scenario if they are bolted then maybe it would stay. but if not it would genuinely topple over very quickly imo. it's generally just some thin metal baseplates set on the floor to start, with a metal framework on either side of each section for the shelves that hold the product and pegboard slid between the frame. we had a car run through the front of the store once and it just moved the shelf with ease. an earthquake would definitely have them domino'ing all over. maybe not every store is like that but they all generally look the same to me everywhere i go
I experienced a 7.4 earthquake in Japan once. Scariest sh’t ever. It’s not even the ground shaking and you can hold onto nothing as you’re thrown around like a rag doll that is the most terrifying. it’s the sound that the ground is making that gives the whole moment a very surreal touch. It sounds like an angry giant bull that is charging at you. Deep and rumbling. Makes you feel powerless and terrified like a little ant in between the fingers of a human who has the intention of crushing you. Nature is as terrible as it is beautiful.
What I would like to see is a simulation of what an earthquake really sounds like. I have heard some but they weren't even close. The groaning, the walls rattling, and the windows shaking. I can't fully describe the actual noise of an earthquake.
IMO, the reason the shelving units did so well in this simulation is because they're short - only 3 shelves - so their center of gravity is closer to the ground. If the simulation showed full-sized units that you would actually see in stories (or the giants in Costco), the shelves would have toppled over sooner because their center of gravity is higher up.
Costco or Walmart probably run by T-Rexes in the Cretaceous period. Wonder did they pay three fiddy for their groceries. They probably put Trceratops and head of security against the Velociraptors..........
This simulation does a great job at showing the level of movement experienced while inside a building but I hope the viewers don't take the damage shown at face value. In real life, the strain on the building's pillars, especially in larger buildings will cause the building to collapse way earlier than shown in the building, crushing everything underneath. Earthquakes are one of the most terrifying phenomenons to be caught unprepared for.
I totally agree with you even as the creator of this video ☺️ I'm currently working on a simulation featuring an airport which is more realistic in terms of damage. I'm posting the video today
@@EarthquakeSim I just watched the video. Definitely did an amazing job with it. Looks super realistic this time both in terms of movement but also damage
After we had the 8.8 earthquake in 2010 (Chile) the supermarkets implemented straps in the alcohol sections in order to protect wine bottles and other similar glass packages. They have currently relaxed and even though we're always aware we can experience a 8+ earthquake anytime, they've decided they are taking the risk 😂 so I feel sorry for the cleaning staff in advance
Its weird how they started doing it after the earthquake but stopped doing it after years. Shouldn't there be more reason to protect them when an earthquake hasn't came in years?
@@eetuthereindeer6671 Yes! I guess they prioritize aesthethic of the shelves over protection of the goods. I guess at this point they have insurance in case of earthquakes 🤔
Living in an earthquake prone country I could tell you that people here won't even bat an eye for anything under level 5, and usually only start to go "hm. this might be a concern" over level 6, so it's actually pretty eye-opening to see how bad the things we consider "dismissable" would've looked from a different perspective
I was gonna say my area isn't prone to earthquakes but the smaller ones we had I still felt, but I looked at some graphics and idk... Maybe it's slightly prone to it? LMAO Rarely above 3.0 in the Richter scale (but we had a 4.5 a few years ago, and that was crazy).
I'm from Taiwan,same here 😂 Most people will just sit there continue doing their things if the lvl's still under 6 😂 Won't even consider to hide or anything
My thought process quickly went from “Jeez, that would be such a hassle to clean up, I feel bad for people who have to deal with that” to “Okay, is there a way to survive in this situation, where would you hide to give yourself the best chance of not being crushed to death?” Powerful earthquakes are truly terrifying…
@@notawamen2311 Yeah, I heard about that too. I was thinking about where you’d hide as a customer in a similar situation. I thought about hiding near the shelves, but looking at the stronger earthquakes that clearly wasn’t a very good idea… I’m glad not to live in a place that has frequent earthquakes. If you had that in school you may do, so I hope you never have to practice what you learned x(
@@drakadragon9731 Thanks! I’ll keep that in mind, and keep praying that this is one of those pieces of information you remember “just in case” but never have to use.
what I learned: no matter how intense the earthquake: if I'm caught by it in a supermrket, the safest place to be is in a fruit crate (up until 10, when the roof came down on them) They and the fruit in them barely move ;-) ) Great work, really interesting to watch!
Fun fact: depending on where they are standing, most people usually don't notice when it's a 5th grade and below. It's a 6th grade and above when things start falling off. We had an 8.1 here in Mexico and and the building I was at it felt like how the 6th degree was depicted here, stuff thumbling everywhere and doors swinging back and forth. But some people who were in poorly constructed buildings experienced it like the 11 degree one. The way it feels/looks is very relative
That's totally true ! Smallest earthquakes are sometimes hard to "feel" or you can easily be confused and thinking, for instance, that it's just a big truck passing on the road nearby or anything else... Last one we felt was a short magnitude 4.6 and at the exact moment it happened I just had thrown a pretty big bag in my living room. The whole house stuttered like a ramshackle shed and my wife told me "maybe you need to calm down a little bit" 😂
it also depends on how close to surface, if earthquake is small but more close than 10 km, people usually feel it, even it's below 5. those ones are usually short, giving a feeling like someone kicked the floor below or you're having dizziness. I also live in an earthquake prone area and buildings are usually not strong.
It's at least somewhat reassuring that the simulated structure here is made to look like a modern building with proper up to code standards. What is really sad are older buildings constructed before this time or areas where any quake magnitude isn't prepared for it! Im a native Californian and I'm pretty "used to" them and I have a reflex in situations to know which ones are the kind to get concerned about over the minor ones!
I'm impressed how the shelves stood their ground for most of the sim. The results of the last few are extremely scary. I've been in a earthquake that was almost a 6 where it started, but from where I was at the time, it felt more like a 4. That was scarier than bunkering down for hurricanes (which I've done at least three times).
Same here, Northridge was 35 miles from my house. My husband lived closer and was shaken like a blender in his apartment. My wall came and hit me as I was getting out of bed, twice! I can laugh now, but that was terrifying enough, what he went through was at least a magnitude stronger than what I felt.
Have you ever been in the eye of a hurricane? It's pretty cool! Suddenly it's totally calm like before a storm but feels odd, can small the ozone, then 15 minutes later BAM the very worst winds suddenly hit!
I live in tornado alley and have had to go to a closet at least ten times in 15 years m, around once every two years, and that's only when it was strong enough to hide. Been in a hail storm with hail pieces that were the size of my hand and totaled my moms car. If I was in an earthquake, I would have a panic attack. I can handle sirens. Not the earth itself shaking.
@@localsatanist I legit had a panic attack when I was in an earthquake, I was still a young enough kid for my mom to have thought I was the cause of the shaking first. My first instinct was to hide under the table but I learned that the safest thing to do indoors is hide under a door frame because that's the most stable part of the house, I'm not sure about all to protocols for outdoors. The good news is that most earthquakes are barely even noticeable to the average person, but when you can feel them it's terrifying.
Labeling each level with what percentage of G it was was so helpful, I have never before had a way of picturing what types of forces were involved in an earthquake. However I have fallen off a chair before! So I am fairly familiar with what, say, 80% of that acceleration would feel like. Also, apparently buildings are not constructed to be moved faster than the speed of gravity, they just shred at 1.5g+ . The simulation of chicxulub was unexpected but so cool, I have not had any kind of reference frame for that, and given that the building seems to cave in instantly, the catastrophic forces involved seem to overtop even this simulation
I appreciate your feedback so much! :) you're right about falling off a chair! it's probably about 80%. Just imagine you are in a waterpark about to do a vertical plunge on one of the rides. 1 G. That is scary :D
Those are some impressive shelving units. I can barely assemble a bookcase that doesn't fall over. Half them are still standing up after an asteroid impact.
I was 15 years old when experienced the 8.8 magnitude earthquake in Chile, 2010. It was 3:34 am and it started very slowly, and then was it was getting faster and stronger, exponientally. I remember seeing the streets with all the cars bouncing up and down, side to side, the light poles were literally dancing. I was really shocked, couldn't say a word, only living the moment (and hearing my mom's screams, lol).
I'm even more amazed that the power never went off. That supermarket obviously doesn't get it's power from Duke Energy, the Lucas Electrics of power companies.
Magnitude 1 - only detected on seismograms Magnitude 2 - least noticeable shakes on hanging objects Magnitude 3 - noticeable shakes on hanging objects Magnitude 4 - smaller objects began to fall off, early signs something went wrong Magnitude 5 - small object fall out, occasionally, furnitures noticed a shake, better go outside if possible *FAST* Magnitude 6 - Furniture starts to shake moderately, captable to make flatscreen tv on ground, debris will begin fall out, immediately go outside FAST, can crrate flash floods Magnitude 7 - now furniture shakes intensely and captable to fall out nearby shelves to the ground, more debris will fall out, can spawn tsunami, it gets increasing larger per magnitude Magnitude 8 - any of shaking objects are fatal, and larger debris fall out too, least noticeable tremor cracks from the ground it gets increasing larger per magnitude, if you live in apartment, game over. Magnitude 9 - inside of every building are death sentence, and outside were somewhat nowhere safe Magnitude 10 - couple and most of building began to collapse, outside arent safe, city wide killer
As a person who lives in a very active earthquake zone, smaller objects began to fall off in a 6, is more safer stay in your place that go out fast, in a 7 you still safe inside because of the possibility of fallen windows (is hard to happen)
@LosAngelesElevators intensity is different than magnitude. Magnitude are used to measure how much energy release by an earthquake, when intensity tell how strong shaking felt and effect to object and building (intensity will be lower in place far from epicenter or if earthquake is deeper). Mercalli intensity scale ranged from I/1 (not felt) to XII/12 (total destruction). Turkiye earthquake have max intensity of XII.
Not at all. Many of the buildings in Earthquake zones are built with Anti Seismic architecture. Without it, real hard hitting earthquakes would cause CONSIDERABLY more destruction.
@@BuglordSupreme I was under the impression that suggesting ceilings are held up with Dental Floss would have designated my comment to the Humous category.
Me and my family survived the Yogyakarta 2006 earthquake at IX MMI. It's most terrifying moment in my life. Even I crawling to escape from our house, I can't walk or run. Sadly more of 5000 people lost their lives.
It's so amazing how with each increment on the MMI, the ground peak acceleration rises exponentially greater than the previous. Just when you see it's only at the fifth level of the scale and it's getting intense, that's nothing yet until you reach the maximum level.
Always an unsettling sight. Anything above the middle of the chart I was feeling scared to watch. Then there was the vertical (bounce) movement, which I didn't account for. That is terrifying. The other thing to think about too, is when you start getting quakes above 6.0, they start lasting a long time. So when you have something like an 8.0 it will seem like the violent shaking won't stop. Chile when they experienced a 9.0, the shaking lasted 10 minutes. I can not even comprehend that. I would probably lose my mind.
Concerning your point about large quakes lasting a long time, it's not completely true. It ultimately depends on the type of fault which the quake occurs on. Subduction faults, which cause the massive quakes like in Japan and Chile, tend to cause quakes upwards of high 7s to low 9s due to the amount of force needed to shove one plate under another and it takes a while for the upper plate to settle back into place. Slip strike faults have quakes up to the low 8s which, while causing a lot of damage, don't tend to last that long as there is less pressure needed to move two plates side by side. For example, the 1989 Loma Prieta quake mag 6.9, only lasted about 15 seconds. And LA's Northridge quake mag 6.7, only lasted a max 20 seconds. The hard shaking for these quakes is over pretty fast. It just feels like an eternity when you're experiencing one. If you ever get a chance to visit a natural history or science museum that has a shake room, go try it out. It's pretty fun and you get to experience what various quake levels are like. Disclaimer: I've lived in CA for longer than I'll admit and have experienced three major quakes (Loma Prieta, Northridge, and Hector Mine). After you go through one of these big quakes, quakes overall stop being scary and you find anything less than a mid-5 boring.
As someone said above, the intensity doesn't stay the same through the entire earthquake. There is nothing to do, just staying in a safe spot and waiting for it to end, it can't last forever 👀
I live in Costa Rica - we have earthquakes all the time - usually 4s or 5s. You get used to them. But we've had a couple above 7. Those are not fun. Not fun at all. The worst part is that it can start off feeling like a regular minor quake but then suddenly it gets real violent.
Also the closer to the epicenter you are the shorter the earthquake actually is. It is stronger and more violent at the epicenter but it relatively short lasting (unless there are after-quakes). As the wave moves it's strength decreases and changes (less shaking, more waving - it feels like you are on a ship on a sea) but lasts longer because each of the high frequency wave turns into a wave with lover frequency, moving slowly though the ground over many kms, one wave after another till the waves weaken enough to not be felt anymore. Look how seismographs look near epicenter (short lasting but high lines) and how they look many kms away (shorter lines but spread over a longer period of time). I don't know about the "Chile when they experienced a 9.0, the shaking lasted 10 minutes" but it's possible the 9.0 quake was short lasting but people a few kms away could experience a level 7 earthquake (which is also quite damaging) that lasted 10 minutes. And the media simply combined those two information, making "a 9.0 earthquake last for 10 minutes".
@@Astrid-88 Valdivia 1960's earthquake lasted about 10 minutes. It was 9.5 Mw, and released 20% of all seismic energy of the 20th century during those 10 minutes. Also this quake, and most megathrust earthquakes have faulting over hundreds of kilometers... That's why these shakemaps have elongated forms... (1960's earthquake for example) earthquake.usgs.gov/earthquakes/eventpage/official19600522191120_30/map For the Valdivia earthquake about 1.000 Km of a tectonic plate moved several meters under the other, it's not just a point moving. (although it has to start moving somewhere, so there's an epicenter, but after that the faulting propagates and then there's a whole line of faulting). To try and paint the picture... After this kind of quakes, if you GPS your house you'd find it moved up to several meters in some direction, it's not just shaking...
This is eye opening! As a grocery clerk… my old, decrepit store is not designed as sturdily as this, and would most definitely not survive past 10. The ceiling tiles would fall before 5, the pipes would snap and the shelves would collapse at 8 if we were lucky… and the building would succumb soon after. My advice, know your emergency exits and protect your head. Run out of the aisles- especially those with large bags of product and canned goods, run away from the coolers with glass doors, and watch out for the hanging/falling signs. If you have to go through a back room, be especially wary of rolling carts, stacked pallets, and falling items. If you make it outside, watch out for falling signs and pieces of the building.
One of the scariest things in earthquake is the sound. This has only stupid bgm but in reality, Everything’s falling down on the floor, glasses are shattered, shelves and tables are rattling, walls are cracking, doors are banging, electrical lines probably buzzing, powers go off and on and the ground is rumbling. Those sounds really make you panic
Excellent video! I'm terrified! And the presentation of Level 13 was perfectly dread-inducing, so I enjoyed that as a little surprise at the end too :D Well done!
I went through the 9.1 in Japan back in 2011. After that, I only ever felt genuine concern over a 7. But that shaking of the 9? You *NEVER* forget it. I still occasionally have nightmares to this day about it.
As someone who experienced the Christchurch 2010 7.1/2011 6.7 earthquakes although not in the city (an hour out of it) and many others I don't feel anything under a 5 and don't get concerned till around mag 5.5-6
@haipydragon5965 2 tips. 1. It's not the earthquake, it's the collapsing buildings that kill people. So get well clear of buildings. 2. If you live near an ocean, learn the highest possible ground and how to get to it quickly. Assume traffic jams etc and you'd have to run. Then have a route to get there
This was an awesome computer simulation, thanks! My dog fell a small one that happened a couple hundred miles away, in Virginia, around a decade ago. I was sitting on my back porch reading and he suddenly got up from where he was napping and went to the door and looked at me like "should we go inside? What just happened?" When he saw I didn't budge he laid back down. About half an hour later my mom called and asked if I had felt it, a few people did in our city but you had to be in exactly the right place, and I wasn't. I presume these are all supposed to be at the store is at the epicenter? It's amazing how they go up and intensity so much. Also to think what it must be like for people who are not in well-constructed buildings like this simulation store was.
I remember that earthquake. Was in Richmond at the time, lasted maybe 5 to 10 seconds with no noticeable aftereffects. Most significant impact was all cell phone lines being busy afterwards because so many people were calling friends and family
I was around 5 and living in Richmond when that earthquake happened. I remember I was watching the fresh beat band and the tv began shaking. my mom was convinced our dryer had fallen but then our neighbor came over and asked if we felt it. weird memory for sure lol
I'm in California and my cockatiel feels them, no matter how small. She freaks out and I'll check USGS a minute or two later, sure enough, a very small quake happened nearby.
He said in a comment that the simulated store was artificially super sturdy so we could see the shaking, and that it would have collapsed at 8 normally.
Kia ora. I'm from Christchurch, N.Z., which on 22 February 2011 attained for a few weeks until the Japan earthquake, the dubious honour of having the strongest ground motion recorded in an earthquake. In this case it was an aftershock of the 04 September 2010 Canterbury earthquake. Shaking intensities on 22 February 2011 at the epicentre near the port town of Lyttelton were MMIX, possibly MMX. There was vertical motion almost as strong as the horizontal motion with - although it was later downgraded to about 1.5g - 2.2g being recorded at Redcliffs Primary School very near the epicentre which was thought to have had shaking intensities between MMIX and MMX. This is a good video and well done on making it. Based on what people have told me, I'd like to add a few comments here that are hopefully useful should you make future videos. So: 1) People in Lyttelton reported fridges and freezer units in the local supermarket walking and bouncing; large items such as microwaves and televisions were physically flung from whatever they sat on. 2) I was in a five story building on the 4th floor about 12km from the epicentre. Peak Ground Acceleration was about 0.8; the lifts failed, book shelves emptied and large things like microwaves in the staff cafeteria bodily moved. 3) Big basaltic cliffs (part of an extinct volcano) around Redcliffs, Sumner and Scarborough lost metres of frontage from rock falls - houses that were 10 metres from the cliff's were now only a couple of metre and had to be abandoned; ones on the cliff face were demolished. You can probably find more about the peak ground acceleration in Christchurch pretty easily on Google. Cheers!
I very appreciate you adding an asteroid impact to the list. I’ve always wondered what that would look like. If I was in that store though I would’ve thought that Godzilla was stomping outside lol.
Each magnitude up is an exponential climb That's why anything above 9 is remarkably rare, because to go beyond that is a huge leap from even the strongest "currently" known quakes. Nice work with the simulation btw! That's pretty close to footage I've seen of such seismic breaks. You use Bullet Constraints Builder?
1: Barely anything 2: Barely moving 3: Moving a little more 4: Things start to fall 5: You might get knocked off your feet 6: It’s no longer safe to be in the isles at this point 7: Getting worse 8: Shelves start to break from the stress 9: Shelves and other large objects start moving across the floor 10: You should consider running for your life at this point 11: The structural integrity of the store becomes compromised and the ceiling begins to fall 12: YOU ARE DEAD AND SO IS THE STORE 13: THERE. IS. NO. ESCAPE.
Very interesting stuff! A couple of suggestions for future sims: - Same as this video, except the quake durations are increased to 30 or 60 seconds each. - Thrust fault sims, where there is a vertical component to the acceleration as well as horizontal. Thank you for considering!
@@BuddyLee23 not sure people understand the Richter scale either, we're just used to seeing it in the News. But the MMI is the new standard for a good reason I suppose, we'll get used to it.
@@BuddyLee23 the Richter scale is no longer used, the standard one nowadays is the Moment Magnitude scale, with each grade, the earthquake increases about 30 times it's magnitude. For example, a magnitude 6 earthquake will unleash 30 times more energy than a magnitude 5 one. It's a logarithmic scale. As for the MMI scale, this one measures intensity, and this can be subjective depending on how far you are from the earthquake or the terrain, so this can be different depending on your current location, even people may have different perception of the intensity of an earthquake
Being in the UK we don't get to experience biggies like the rest of you, but a few years back a 4.5 hit about 20 miles away, and I remember being in the kitchen, feeling really odd, thinking 'wtf is going on?', then hearing a roar outside, like a low flying jet, and the kitchen window blinds banging back and fore in the window. Snapped out of my bewilderment and went straight on the net to confirm the EQ. It was strange how I knew something was wrong before I saw the movement of the blinds. Don't want to experience anything bigger, thank you very much!
When I was a freshman engineering student in college, we were touring one of the facilities with an earthquake simulator lab. I was the only California kid in the whole group and the looks on everyone else’s faces when the professor explained - with an erector set model and a machine - that California buildings intentionally sway back and forth for earthquakes. And the students didn’t believe me when I told them we mostly ignore and/or don’t notice and/or sleep through anything under about a 5.
I went to Cali once to visit extended family and got hit by a (in my experience) bad earthquake, I think it was about 4/5. I asked my step-aunt about it the next morning and she said she didn't notice since it didn't wake up xD idk how y'all do it
It would be scary to experience earthquakes like this. I live in a state that doesn’t have earthquakes, but has tornadoes. I’ve never been to California but I know that state has earthquakes and wildfires
A reminder that this is using the Mercalli Scale, NOT the Richter Scale. So Intensity X does not mean Magnitude 10.0. Intensity X is roughly a Magnitude 6.5-7.0 on the Richter Scale.
The sign in the back of the store, Earthquake Cafe, reminded me of a hands-on exhibit that was (maybe still is?) at the Carnegie Science Center in Pittsburgh that was also named Earthquake Cafe (or something similar. It's been a couple decades since I was last there). It was a motion simulator with a little cafe table inside that you could sit at. You then chose from a menu of earthquakes (with different intensities) to experience, and the simulator shook with the intensity of that quake. It was probably designed like this video, with the idea of showing you how different earthquakes could be, but I'm pretty sure every kid just went in and picked the most intense earthquake, which was the massive quake that hit Chile in the 70s.
Very cool video! I think as someone who doesn’t live in an earthquake zone I’m probably the target audience for this. Now I know a lot more about the intensities beyond Big Number = Scary, thanks!! :)
I’d be very curious to see what this would look like with more accurate models for the cans. Since cans are designed to slightly nestle into each other, I would think they’d do a significantly better job staying stacked irl than they do in this sim.
Absolutely a very shocking and sobering video! I was in San Francisco in October 89 at the World Series and survived that! I was in Anchorage AK in 2004 visiting my parents when the Indian Ocean Earthquake and Tsunami occurred!!! Luckily the Tsunami alert was canceled but felt Earthquakes albeit smaller the same day! In 2018 I was in Anchorage again with the 7.0 shaker! My parents were in the 64 Great Alaska Earthquake 9.2 and survived that! I was born 4 years later in 68!
It will be interesting to see the evolution of this sim software. Right now it's rudimentary but still exciting. Reminds me of the start of MetaBallStudios. Definitely subbed and keep up the good work. This is an inferesting subject.
It is getting better every week :) I have recently just started experimenting with real lighting and shadows. The simulations take more time to render it but it is worth it. I'm thinking of getting a second PC to render my work faster...
Earthquakes are so interesting to me. I've lived in California all my life, both northern and southern, so I've definitely felt some pretty major ones. The most significant recent one was a 6.4 up here in Humboldt County in December of 2022. Strangely, we had a ~6.0 earthquake on the exact same day a year prior. Wild coincidence.
Yeah! About a month ago there was a 5.5 earthquake near where I live, and so it was the first earthquake I've ever felt, even though I've always lived in California. I've heard that the earthquake drought might be ending, so keep your eye out for more.
Since I experienced a Mercalli 7 earthquake as a kid (in Germany), my brain locks down whenever I experience another one. There have been at least 3 very noticeable earthquakes in my adulthood which I did wake up from, but every time I immediately got brain fog. My brain just got very, very slow then, I couldn't control my actions, and my subconsciousness invented some stupid excuse for the shaking. It's disappointing, actually. 😆 Must be some kind of ptsd, I guess, as back in 1992 my family found me with my eyes wide open, paralized, not responding or reacting to them. Can't remember how I got out of this state.
I think it depends more on the type of construction, in Chile and Japan they have excellent constructions. In the M8.8 earthquake in Chile (2010), collapsed buildings were one-off events and in the M9.1 earthquake in Japan (2011), there were no collapsed buildings. Both the earthquake in Chile and Japan reached maximum intensity between VIII to IX on the Mercalli scale. Greetings from south-central Chile. 🇨🇱
Interesting, also big props to the crew resetting the 'store' each time. That was a lot of fiddly work. Since I just found this channel I have no clue if you have addressed the fact that in the USA earthquakes in the east are very different because the rock and fault structure is very different.
I’m sorry but the physics glitch at 3:46 made me laugh kdjdkdkd that one container at the meat counter just YEETING before the earthquake even really hit kdjfkfkdkdk
There was an earthquake last night. I live in Kazakhstan and thank God I’m in the countryside, but I’m so sorry for the Chinese and Kyrgyz, their buildings were collapsing
I’m disappointed but also impressed that the shelves never once tipped over. I waited the whole vid and the entire building collapsed before a single shelf tipped
This was quite interesting! This is a neat channel, nice work with the simulations. Would have appreciated real world examples to accompany the intensity levels. Poor camera got shaken out of the supermarket at the end. Subscribed!
I think Supermarket is the safest building when there is an earthquake 😗 It seems so tough and If... when the roofs fell it probably wouldn't have directly hit us, the shelves would have held the material, then if we were buried there we got enough supplies until the rescue team came, we won't starve to death either.
A lot of supermarkets that I've seen come across my company's desk (I work in commercial insurance) tend to be either wood frame or concrete block, which tend to be more resistant to quakes especially if up to code. I'd feel safe if caught in most strip malls during an event like these
As someone who lives in an earthquake-prone country, I can tell you that the safest place to be in the event of an earthquake is outside rather than inside a building. This is because if a building collapses and blocks the entrance and exit, it will be difficult to evacuate to another safe place, and if you are in a coastal area, there is a risk of secondary disasters such as tsunami, which will also make it difficult to escape.
I live in a remote city in peninsula where Level 3 to 4 happens virtually every week. Not too long ago, launch at work cut short by Level 6. Spending time inside door openings that are part of the load bearing walls during shakes almost became the routine.
A fact many people might not be aware of is that for every full step to the next number, the energy of the earthquake multiplies by 30. This means that an earthquake of 7 has roughly 900 times (30x30) the energy of an earthquake of 5. I know this about the intensity scale, but the magnitude scale is more commonly mentioned and to some degree those obviously correspond with each other.
In one of my University geology classes, I learned that if we ever had a earthquake of 10 on the Richter scale, the tremors would be felt everywhere on earth.
Impossible. As someone who has been in an 8.4 earthquake I can assure it's barely felt in other states. A 10 would only feel in more surrounding states and in lower intensity. That's it.
@@silverendlessness4052 Earthquake intensity is exponential. The difference between 3 and 4 is bigger that that between 2 and 3, BUT WAY smaller than that between 5-6
This is very good! I grew up in California. Most earthquakes growing up were like a 3-4 not enough to damage, just enough to shake everything off the shelves and scare the ish out of you lol. Property damage doesn't really start until 6, from there on its gets pretty hellish. I think the simulation understated the 9 ans 10 though. You have whole buildings falling apart at that point. I was around for the Northridge earthquake, that thing was a monster and I think it was an 8 😬
Generally speaking, the larger the magnitude, the longer the shaking lasts and, invariably, the higher the MMI. So, here, it would have been nice to see the simulations reflect this (with longer shake times the higher the intensity).
yep! it's hard simulating more than 30 seconds. BUT I did simulate the 9.0 Cascadia quake, a 4 minute simulation on my channel :) it features a gas station
Just wanted to note that Turkey is an earthquake high risk country and most buildings are not built according to latest building codes. Istanbul (20 million people) and surrounding Marmara area (10 million) is expecting 7.2-7.6 earthquakes very soon. The minister of agriculture said that up to 600.000 buildings could collapse. A quick math; 600.000 x 4 floors x 2 apartments on each floor x 2 people = 9.600.000 lives in direct risk. If you live or travel to Turkey, please make sure the buildings you live/stay/work/visit are new (though new doesn’t necessarily mean resistant as there is very little audit/checks😢), have your go bag ready, be aware of tsunami dangers, look at your escape routes (look at buildings, roads etc) and research the topic endlessly. The rest of the world; please help us😢😢😢
I remember the Great East Japan Earthquake. I was 7 years old then. I lived Tokyo, so I didn't shaken so much (about intensity 6) but I really be scared. But many people in japan, and of course me, accustomed to feeling earthquakes. So that intensity 3 or 4, i think that is weak... And I think in intensity 9, the racks moves more violently, and signboards on the ceiling falls. sorry for my poor English because of I'm japanese...
I love 3D simulations usually. I wish there were more simulations for underwater things like the depth of some oceans or even creatures. Extinct or creatures from stories. But this was great too.
Y’know what earthquake scenario I think about fairly regularly? The Cascadia subduction zone that stretches from Alaska down to Oregon. If the whole fault was to shift at once it’d produce an earthquake of at least 9.0 with horribly devastating effect since Alaska didn’t adopt the same earthquake safety building codes that states like California have until the mid 90s.
Thank you! I’ve never experienced an earthquake (and hopefully never will) people always talk about numbers, intensity and how horrible it can get but, that always seemed so unreal. Now I feel like I know more and can understand other’s experiences of earthquakes better. Thank you, and thanks to TH-cam algorithm for recommending this to me at 2am, the best time to learn new things:D

@@EarthquakeSim the last one is caseoh jumped
I feel like it’s important to mention, especially for those who don’t know, in earthquake prone areas, buildings are made to be able to sway a bit with the earthquake, so the building swaying as the earthquake is happening is actually normal and realistic in the simulation.
Elementary knowledge
it’s to be able to handle the pressure and energy of the earthquake. in japan they are doing this with their sky scrapers and similar buildings, to avoid the likeliness of falling down.
TL ; DR
to go with the flow of energy built up by the earth quake and not fall down.

I think it's really impressive for the shelves to stay mostly undamaged and upright for anything less than a gigantic asteroid strike.Someone should build the store as sturdy as these shelves.
IKR? like i didnt register how bad they were bc the shelves stayed up!
Also a massive shoutout to the ceiling not collapsing despite all the broken pillars. Must be roman concrete 😂
Yeah i was like expecting the shelves to be thrown around and flying or something but i guess i underestimated how heavy they were and the roofs collapsing jumpscared me
they are not bolted to the floor in most cases imo. think about how often stores do a remodel or rearrange things. when they remodeled the store i worked at they basically got a little jack thing and some sliders and lifted the whole thing up and just slid the shelves around, product on it and everything. so in this scenario if they are bolted then maybe it would stay. but if not it would genuinely topple over very quickly imo. it's generally just some thin metal baseplates set on the floor to start, with a metal framework on either side of each section for the shelves that hold the product and pegboard slid between the frame. we had a car run through the front of the store once and it just moved the shelf with ease. an earthquake would definitely have them domino'ing all over. maybe not every store is like that but they all generally look the same to me everywhere i go
Yeah. The shelves stayed upright alot more easily than the roof stayed intact
I experienced a 7.4 earthquake in Japan once. Scariest sh’t ever.
It’s not even the ground shaking and you can hold onto nothing as you’re thrown around like a rag doll that is the most terrifying. it’s the sound that the ground is making that gives the whole moment a very surreal touch. It sounds like an angry giant bull that is charging at you. Deep and rumbling. Makes you feel powerless and terrified like a little ant in between the fingers of a human who has the intention of crushing you.
Nature is as terrible as it is beautiful.
Totally agree with you! Thanks for the feedback!
How cute, i live in Chile, a minute and a half in a 8.8 earthquake 🫠🫠
@@NeoSpaceMax so what exactly did you get out of comparing? this isnt a race 💀
What I would like to see is a simulation of what an earthquake really sounds like. I have heard some but they weren't even close. The groaning, the walls rattling, and the windows shaking. I can't fully describe the actual noise of an earthquake.
same as a person who is in Turkey
Can we take time to appreciate that the workers cleaned the store again and again so fast?
Hehe!! Yes we should!!
no they just set up multiple camera in different angles of view
THE INTENSITY CHANGE:
Its not real though, it’s just a simulation.
@@waterydehydratedmilk its a joke
Yeah no.
IMO, the reason the shelving units did so well in this simulation is because they're short - only 3 shelves - so their center of gravity is closer to the ground. If the simulation showed full-sized units that you would actually see in stories (or the giants in Costco), the shelves would have toppled over sooner because their center of gravity is higher up.
This is such a good explanation!! Indeed, I made the shelves only 1.6 m tall
I work at a Sam's club, and I can confirm this. Those things are death traps waiting to happen.
Plus there's no friction between the shelves and the base platform, and I think the shelves should've been simulated as heavier

This simulation does a great job at showing the level of movement experienced while inside a building but I hope the viewers don't take the damage shown at face value. In real life, the strain on the building's pillars, especially in larger buildings will cause the building to collapse way earlier than shown in the building, crushing everything underneath. Earthquakes are one of the most terrifying phenomenons to be caught unprepared for.
I totally agree with you even as the creator of this video ☺️ I'm currently working on a simulation featuring an airport which is more realistic in terms of damage. I'm posting the video today
Exactly. Though I never was in one I have watched a lot footage. Most notably is the lack of noise and dust and debris from the ceiling objects.
@@EarthquakeSim I just watched the video. Definitely did an amazing job with it. Looks super realistic this time both in terms of movement but also damage
Yea if this was the first floor of like a 5 floor building the maket would collapse like at 9
And also the material of the edifications would change the stiuation a lot
After we had the 8.8 earthquake in 2010 (Chile) the supermarkets implemented straps in the alcohol sections in order to protect wine bottles and other similar glass packages. They have currently relaxed and even though we're always aware we can experience a 8+ earthquake anytime, they've decided they are taking the risk 😂 so I feel sorry for the cleaning staff in advance
damn but why just the wine💀😭
I remember seeing a video of an earthquake in Japan where a red wine bottle had fallen down, and the comments were full of "omg is that blood?".
@@QwerYT4819 priorities 😂
Its weird how they started doing it after the earthquake but stopped doing it after years. Shouldn't there be more reason to protect them when an earthquake hasn't came in years?
@@eetuthereindeer6671 Yes! I guess they prioritize aesthethic of the shelves over protection of the goods. I guess at this point they have insurance in case of earthquakes 🤔
Living in an earthquake prone country I could tell you that people here won't even bat an eye for anything under level 5, and usually only start to go "hm. this might be a concern" over level 6, so it's actually pretty eye-opening to see how bad the things we consider "dismissable" would've looked from a different perspective
🗾
I'm from Chile. I can confirm this.
I was gonna say my area isn't prone to earthquakes but the smaller ones we had I still felt, but I looked at some graphics and idk... Maybe it's slightly prone to it? LMAO
Rarely above 3.0 in the Richter scale (but we had a 4.5 a few years ago, and that was crazy).
I'm from Taiwan,same here 😂
Most people will just sit there continue doing their things if the lvl's still under 6 😂
Won't even consider to hide or anything
Most earthquakes ive experienced is 5-6 above that is a rare phenomenon i think
My thought process quickly went from “Jeez, that would be such a hassle to clean up, I feel bad for people who have to deal with that” to “Okay, is there a way to survive in this situation, where would you hide to give yourself the best chance of not being crushed to death?”
Powerful earthquakes are truly terrifying…
School has taught us to go under or at least put your neck and head under a table of some sort when we did earthquake drills
@@notawamen2311 Yeah, I heard about that too. I was thinking about where you’d hide as a customer in a similar situation. I thought about hiding near the shelves, but looking at the stronger earthquakes that clearly wasn’t a very good idea…
I’m glad not to live in a place that has frequent earthquakes. If you had that in school you may do, so I hope you never have to practice what you learned x(
@@viablue8143 if there's nowhere to hide I was taught to stand in a doorway, they are relatively strong because of their design
@@drakadragon9731 Thanks! I’ll keep that in mind, and keep praying that this is one of those pieces of information you remember “just in case” but never have to use.
I wouldn't say quickly, even 9 felt fairly survivable
what I learned: no matter how intense the earthquake: if I'm caught by it in a supermrket, the safest place to be is in a fruit crate (up until 10, when the roof came down on them) They and the fruit in them barely move ;-) ) Great work, really interesting to watch!
Good idea! That way, If you're caught under the rubble, you can munch on some yummy fruit while you wait to be rescued.
I noticed the same thing. The fruit crates are incredibly strong. All kidding aside, thank you for this video.
I saw that climbing into the bottom shelf of the toilet paper aisle would protect me. After a large quake, be sure to check that spot!
Being by the cameraman is also a good place. The ceiling hardly ever fell on him.
I kept waiting to see the fruit pop out, but they never did, although if the building hadn't collapsed on them, they may have!
Fun fact: depending on where they are standing, most people usually don't notice when it's a 5th grade and below. It's a 6th grade and above when things start falling off. We had an 8.1 here in Mexico and and the building I was at it felt like how the 6th degree was depicted here, stuff thumbling everywhere and doors swinging back and forth. But some people who were in poorly constructed buildings experienced it like the 11 degree one. The way it feels/looks is very relative
That's totally true ! Smallest earthquakes are sometimes hard to "feel" or you can easily be confused and thinking, for instance, that it's just a big truck passing on the road nearby or anything else... Last one we felt was a short magnitude 4.6 and at the exact moment it happened I just had thrown a pretty big bag in my living room. The whole house stuttered like a ramshackle shed and my wife told me "maybe you need to calm down a little bit" 😂
it also depends on how close to surface, if earthquake is small but more close than 10 km, people usually feel it, even it's below 5. those ones are usually short, giving a feeling like someone kicked the floor below or you're having dizziness. I also live in an earthquake prone area and buildings are usually not strong.
the fact that the entire roof of the building collapsed before a single shelf fell over is honestly something i never would've expected.
It's at least somewhat reassuring that the simulated structure here is made to look like a modern building with proper up to code standards. What is really sad are older buildings constructed before this time or areas where any quake magnitude isn't prepared for it! Im a native Californian and I'm pretty "used to" them and I have a reflex in situations to know which ones are the kind to get concerned about over the minor ones!

I remember what my Structural Geology professor in college always said, "earthquakes don't kill people, buildings do".
I'm impressed how the shelves stood their ground for most of the sim. The results of the last few are extremely scary. I've been in a earthquake that was almost a 6 where it started, but from where I was at the time, it felt more like a 4. That was scarier than bunkering down for hurricanes (which I've done at least three times).
Same here, Northridge was 35 miles from my house. My husband lived closer and was shaken like a blender in his apartment. My wall came and hit me as I was getting out of bed, twice! I can laugh now, but that was terrifying enough, what he went through was at least a magnitude stronger than what I felt.
Have you ever been in the eye of a hurricane? It's pretty cool! Suddenly it's totally calm like before a storm but feels odd, can small the ozone, then 15 minutes later BAM the very worst winds suddenly hit!
Ive been in a earthquake IX-X, nothing happened to my building tho, but ending felt like XI.
I live in tornado alley and have had to go to a closet at least ten times in 15 years m, around once every two years, and that's only when it was strong enough to hide. Been in a hail storm with hail pieces that were the size of my hand and totaled my moms car. If I was in an earthquake, I would have a panic attack. I can handle sirens. Not the earth itself shaking.
@@localsatanist I legit had a panic attack when I was in an earthquake, I was still a young enough kid for my mom to have thought I was the cause of the shaking first. My first instinct was to hide under the table but I learned that the safest thing to do indoors is hide under a door frame because that's the most stable part of the house, I'm not sure about all to protocols for outdoors. The good news is that most earthquakes are barely even noticeable to the average person, but when you can feel them it's terrifying.
Labeling each level with what percentage of G it was was so helpful, I have never before had a way of picturing what types of forces were involved in an earthquake. However I have fallen off a chair before! So I am fairly familiar with what, say, 80% of that acceleration would feel like. Also, apparently buildings are not constructed to be moved faster than the speed of gravity, they just shred at 1.5g+ . The simulation of chicxulub was unexpected but so cool, I have not had any kind of reference frame for that, and given that the building seems to cave in instantly, the catastrophic forces involved seem to overtop even this simulation
I appreciate your feedback so much! :) you're right about falling off a chair! it's probably about 80%. Just imagine you are in a waterpark about to do a vertical plunge on one of the rides. 1 G. That is scary :D
At 1G 4:52 the pillar gave out, I don’t know if it was load bearing pillar
Props to the cameraman for recording and surviving earthquake all the way up to scale 12.

Those are some impressive shelving units. I can barely assemble a bookcase that doesn't fall over. Half them are still standing up after an asteroid impact.

Lol, just imagine. By now, every time an earthquake starts, the store gets completely obliterated from existance.
@@SlumberBear2k no more inflation
I was 15 years old when experienced the 8.8 magnitude earthquake in Chile, 2010. It was 3:34 am and it started very slowly, and then was it was getting faster and stronger, exponientally. I remember seeing the streets with all the cars bouncing up and down, side to side, the light poles were literally dancing. I was really shocked, couldn't say a word, only living the moment (and hearing my mom's screams, lol).
I'm amazed those shelves stayed up through all that, even when the roof caved in or the entire building fell on top of them they stayed upright!
I'm even more amazed at the fruit boxes. They didn't break, didn't spill and even were still left standing when the roof caved in! :D
I'm even more amazed that the power never went off. That supermarket obviously doesn't get it's power from Duke Energy, the Lucas Electrics of power companies.
Magnitude 1 - only detected on seismograms
Magnitude 2 - least noticeable shakes on hanging objects
Magnitude 3 - noticeable shakes on hanging objects
Magnitude 4 - smaller objects began to fall off, early signs something went wrong
Magnitude 5 - small object fall out, occasionally, furnitures noticed a shake, better go outside if possible *FAST*
Magnitude 6 - Furniture starts to shake moderately, captable to make flatscreen tv on ground, debris will begin fall out, immediately go outside FAST, can crrate flash floods
Magnitude 7 - now furniture shakes intensely and captable to fall out nearby shelves to the ground, more debris will fall out, can spawn tsunami, it gets increasing larger per magnitude
Magnitude 8 - any of shaking objects are fatal, and larger debris fall out too, least noticeable tremor cracks from the ground it gets increasing larger per magnitude, if you live in apartment, game over.
Magnitude 9 - inside of every building are death sentence, and outside were somewhat nowhere safe
Magnitude 10 - couple and most of building began to collapse, outside arent safe, city wide killer
Unless you're outside in an isolated area like in the plains
@Calokifilm the plains
Flash floods are not created by Earthquakes, only tsunamis💀
As a person who lives in a very active earthquake zone, smaller objects began to fall off in a 6, is more safer stay in your place that go out fast, in a 7 you still safe inside because of the possibility of fallen windows (is hard to happen)
Today, April 5th, 2024, at 10:20 am 4.7/8 was felt in NJ

@RyanLeeMultiCraftDepth fallen
@LosAngelesElevators intensity is different than magnitude. Magnitude are used to measure how much energy release by an earthquake, when intensity tell how strong shaking felt and effect to object and building (intensity will be lower in place far from epicenter or if earthquake is deeper). Mercalli intensity scale ranged from I/1 (not felt) to XII/12 (total destruction). Turkiye earthquake have max intensity of XII.

😧
It's so amazing how with each increment on the MMI, the ground peak acceleration rises exponentially greater than the previous.
Just when you see it's only at the fifth level of the scale and it's getting intense, that's nothing yet until you reach the maximum level.
you are absolutely right! :)
I just had a minor earthquake in my homestate Connecticut. My mom told me about & I was surprised & shocked.😮
Always an unsettling sight. Anything above the middle of the chart I was feeling scared to watch. Then there was the vertical (bounce) movement, which I didn't account for. That is terrifying.
The other thing to think about too, is when you start getting quakes above 6.0, they start lasting a long time. So when you have something like an 8.0 it will seem like the violent shaking won't stop. Chile when they experienced a 9.0, the shaking lasted 10 minutes. I can not even comprehend that. I would probably lose my mind.
Concerning your point about large quakes lasting a long time, it's not completely true. It ultimately depends on the type of fault which the quake occurs on. Subduction faults, which cause the massive quakes like in Japan and Chile, tend to cause quakes upwards of high 7s to low 9s due to the amount of force needed to shove one plate under another and it takes a while for the upper plate to settle back into place.
Slip strike faults have quakes up to the low 8s which, while causing a lot of damage, don't tend to last that long as there is less pressure needed to move two plates side by side. For example, the 1989 Loma Prieta quake mag 6.9, only lasted about 15 seconds. And LA's Northridge quake mag 6.7, only lasted a max 20 seconds. The hard shaking for these quakes is over pretty fast. It just feels like an eternity when you're experiencing one. If you ever get a chance to visit a natural history or science museum that has a shake room, go try it out. It's pretty fun and you get to experience what various quake levels are like.
Disclaimer: I've lived in CA for longer than I'll admit and have experienced three major quakes (Loma Prieta, Northridge, and Hector Mine). After you go through one of these big quakes, quakes overall stop being scary and you find anything less than a mid-5 boring.
As someone said above, the intensity doesn't stay the same through the entire earthquake. There is nothing to do, just staying in a safe spot and waiting for it to end, it can't last forever 👀
I live in Costa Rica - we have earthquakes all the time - usually 4s or 5s. You get used to them. But we've had a couple above 7. Those are not fun. Not fun at all. The worst part is that it can start off feeling like a regular minor quake but then suddenly it gets real violent.
Also the closer to the epicenter you are the shorter the earthquake actually is. It is stronger and more violent at the epicenter but it relatively short lasting (unless there are after-quakes). As the wave moves it's strength decreases and changes (less shaking, more waving - it feels like you are on a ship on a sea) but lasts longer because each of the high frequency wave turns into a wave with lover frequency, moving slowly though the ground over many kms, one wave after another till the waves weaken enough to not be felt anymore. Look how seismographs look near epicenter (short lasting but high lines) and how they look many kms away (shorter lines but spread over a longer period of time).
I don't know about the "Chile when they experienced a 9.0, the shaking lasted 10 minutes" but it's possible the 9.0 quake was short lasting but people a few kms away could experience a level 7 earthquake (which is also quite damaging) that lasted 10 minutes. And the media simply combined those two information, making "a 9.0 earthquake last for 10 minutes".
@@Astrid-88 Valdivia 1960's earthquake lasted about 10 minutes.
It was 9.5 Mw, and released 20% of all seismic energy of the 20th century during those 10 minutes.
Also this quake, and most megathrust earthquakes have faulting over hundreds of kilometers... That's why these shakemaps have elongated forms... (1960's earthquake for example)
earthquake.usgs.gov/earthquakes/eventpage/official19600522191120_30/map
For the Valdivia earthquake about 1.000 Km of a tectonic plate moved several meters under the other, it's not just a point moving. (although it has to start moving somewhere, so there's an epicenter, but after that the faulting propagates and then there's a whole line of faulting).
To try and paint the picture... After this kind of quakes, if you GPS your house you'd find it moved up to several meters in some direction, it's not just shaking...
This is eye opening!
As a grocery clerk… my old, decrepit store is not designed as sturdily as this, and would most definitely not survive past 10. The ceiling tiles would fall before 5, the pipes would snap and the shelves would collapse at 8 if we were lucky… and the building would succumb soon after.
My advice, know your emergency exits and protect your head. Run out of the aisles- especially those with large bags of product and canned goods, run away from the coolers with glass doors, and watch out for the hanging/falling signs.
If you have to go through a back room, be especially wary of rolling carts, stacked pallets, and falling items. If you make it outside, watch out for falling signs and pieces of the building.
For someone who lives in a place that (thankfully) never has earthquakes, this is genuinely terrifying
One of the scariest things in earthquake is the sound. This has only stupid bgm but in reality, Everything’s falling down on the floor, glasses are shattered, shelves and tables are rattling, walls are cracking, doors are banging, electrical lines probably buzzing, powers go off and on and the ground is rumbling. Those sounds really make you panic
The circle cakes at 4:27 are sturdy af.
Excellent video! I'm terrified! And the presentation of Level 13 was perfectly dread-inducing, so I enjoyed that as a little surprise at the end too :D Well done!
I went through the 9.1 in Japan back in 2011.
After that, I only ever felt genuine concern over a 7.
But that shaking of the 9?
You *NEVER* forget it. I still occasionally have nightmares to this day about it.
As someone who experienced the Christchurch 2010 7.1/2011 6.7 earthquakes although not in the city (an hour out of it) and many others I don't feel anything under a 5 and don't get concerned till around mag 5.5-6
Any tips for surviving one?
@haipydragon5965 2 tips.
1. It's not the earthquake, it's the collapsing buildings that kill people. So get well clear of buildings.
2. If you live near an ocean, learn the highest possible ground and how to get to it quickly. Assume traffic jams etc and you'd have to run. Then have a route to get there
This was an awesome computer simulation, thanks! My dog fell a small one that happened a couple hundred miles away, in Virginia, around a decade ago. I was sitting on my back porch reading and he suddenly got up from where he was napping and went to the door and looked at me like "should we go inside? What just happened?" When he saw I didn't budge he laid back down. About half an hour later my mom called and asked if I had felt it, a few people did in our city but you had to be in exactly the right place, and I wasn't. I presume these are all supposed to be at the store is at the epicenter? It's amazing how they go up and intensity so much. Also to think what it must be like for people who are not in well-constructed buildings like this simulation store was.
I remember that earthquake. Was in Richmond at the time, lasted maybe 5 to 10 seconds with no noticeable aftereffects. Most significant impact was all cell phone lines being busy afterwards because so many people were calling friends and family
I was around 5 and living in Richmond when that earthquake happened. I remember I was watching the fresh beat band and the tv began shaking. my mom was convinced our dryer had fallen but then our neighbor came over and asked if we felt it. weird memory for sure lol
I felt it as well, but a couple states away from Virginia. It surprised me because earthquakes are so rare in the region.
I'm in California and my cockatiel feels them, no matter how small. She freaks out and I'll check USGS a minute or two later, sure enough, a very small quake happened nearby.
He said in a comment that the simulated store was artificially super sturdy so we could see the shaking, and that it would have collapsed at 8 normally.
Kia ora.
I'm from Christchurch, N.Z., which on 22 February 2011 attained for a few weeks until the Japan earthquake, the dubious honour of having the strongest ground motion recorded in an earthquake. In this case it was an aftershock of the 04 September 2010 Canterbury earthquake. Shaking intensities on 22 February 2011 at the epicentre near the port town of Lyttelton were MMIX, possibly MMX. There was vertical motion almost as strong as the horizontal motion with - although it was later downgraded to about 1.5g - 2.2g being recorded at Redcliffs Primary School very near the epicentre which was thought to have had shaking intensities between MMIX and MMX.
This is a good video and well done on making it. Based on what people have told me, I'd like to add a few comments here that are hopefully useful should you make future videos. So:
1) People in Lyttelton reported fridges and freezer units in the local supermarket walking and bouncing; large items such as microwaves and televisions were physically flung from whatever they sat on.
2) I was in a five story building on the 4th floor about 12km from the epicentre. Peak Ground Acceleration was about 0.8; the lifts failed, book shelves emptied and large things like microwaves in the staff cafeteria bodily moved.
3) Big basaltic cliffs (part of an extinct volcano) around Redcliffs, Sumner and Scarborough lost metres of frontage from rock falls - houses that were 10 metres from the cliff's were now only a couple of metre and had to be abandoned; ones on the cliff face were demolished.
You can probably find more about the peak ground acceleration in Christchurch pretty easily on Google.
Cheers!
I very appreciate you adding an asteroid impact to the list. I’ve always wondered what that would look like. If I was in that store though I would’ve thought that Godzilla was stomping outside lol.
That'd be XIV. 🦕
Each magnitude up is an exponential climb That's why anything above 9 is remarkably rare, because to go beyond that is a huge leap from even the strongest "currently" known quakes. Nice work with the simulation btw! That's pretty close to footage I've seen of such seismic breaks. You use Bullet Constraints Builder?
Yes, says in their description they used BCB
As a Connecticut resident, we had a minor earthquake today, but I didn’t really feel it🤷
1: Barely anything
2: Barely moving
3: Moving a little more
4: Things start to fall
5: You might get knocked off your feet
6: It’s no longer safe to be in the isles at this point
7: Getting worse
8: Shelves start to break from the stress
9: Shelves and other large objects start moving across the floor
10: You should consider running for your life at this point
11: The structural integrity of the store becomes compromised and the ceiling begins to fall
12: YOU ARE DEAD AND SO IS THE STORE
13: THERE. IS. NO. ESCAPE.
1999 earthquake had 2.06g PGA...
it goes from 1 your fine to 13 YOUR ABSOULTLY F*CKED

@@lisagibson2975 and Target stocks are not far behind
Very interesting stuff! A couple of suggestions for future sims:
- Same as this video, except the quake durations are increased to 30 or 60 seconds each.
- Thrust fault sims, where there is a vertical component to the acceleration as well as horizontal.
Thank you for considering!
Maybe add in a Richter scale conversion or something? Not sure how many causal viewers recognize the MMI scale
@@BuddyLee23 not sure people understand the Richter scale either, we're just used to seeing it in the News. But the MMI is the new standard for a good reason I suppose, we'll get used to it.
What does mmi have to do with earthqukes?
The MMI records how much shaking there is I think.
@@BuddyLee23 the Richter scale is no longer used, the standard one nowadays is the Moment Magnitude scale, with each grade, the earthquake increases about 30 times it's magnitude. For example, a magnitude 6 earthquake will unleash 30 times more energy than a magnitude 5 one. It's a logarithmic scale.
As for the MMI scale, this one measures intensity, and this can be subjective depending on how far you are from the earthquake or the terrain, so this can be different depending on your current location, even people may have different perception of the intensity of an earthquake
Being in the UK we don't get to experience biggies like the rest of you, but a few years back a 4.5 hit about 20 miles away, and I remember being in the kitchen, feeling really odd, thinking 'wtf is going on?', then hearing a roar outside, like a low flying jet, and the kitchen window blinds banging back and fore in the window. Snapped out of my bewilderment and went straight on the net to confirm the EQ.
It was strange how I knew something was wrong before I saw the movement of the blinds.
Don't want to experience anything bigger, thank you very much!
You are so welcome!!! Thank you so much for your feedback ☺️
When was this? I'm in Scotland and I've never felt an earthquake in 30 years 😂
we live those freaking daily in Turkey
Texas doesn’t have much earthquakes either, unlike California
When I was a freshman engineering student in college, we were touring one of the facilities with an earthquake simulator lab. I was the only California kid in the whole group and the looks on everyone else’s faces when the professor explained - with an erector set model and a machine - that California buildings intentionally sway back and forth for earthquakes. And the students didn’t believe me when I told them we mostly ignore and/or don’t notice and/or sleep through anything under about a 5.
I went to Cali once to visit extended family and got hit by a (in my experience) bad earthquake, I think it was about 4/5. I asked my step-aunt about it the next morning and she said she didn't notice since it didn't wake up xD idk how y'all do it
I'm from Chile. We don't notice under the 7 degree jaja.
It would be scary to experience earthquakes like this. I live in a state that doesn’t have earthquakes, but has tornadoes. I’ve never been to California but I know that state has earthquakes and wildfires
A reminder that this is using the Mercalli Scale, NOT the Richter Scale. So Intensity X does not mean Magnitude 10.0. Intensity X is roughly a Magnitude 6.5-7.0 on the Richter Scale.
Thank you so much for highlighting this for other viewers☺️

The sign in the back of the store, Earthquake Cafe, reminded me of a hands-on exhibit that was (maybe still is?) at the Carnegie Science Center in Pittsburgh that was also named Earthquake Cafe (or something similar. It's been a couple decades since I was last there). It was a motion simulator with a little cafe table inside that you could sit at. You then chose from a menu of earthquakes (with different intensities) to experience, and the simulator shook with the intensity of that quake. It was probably designed like this video, with the idea of showing you how different earthquakes could be, but I'm pretty sure every kid just went in and picked the most intense earthquake, which was the massive quake that hit Chile in the 70s.
I remember visiting this exact exhibit!! I went in 2014 so I don’t know if it’s still there
That would be so fun to do!
@@Meanderonthemoon holy crap! It still exists!?! I remember going there to that same exhibit the mid 90s!
@@Blood-PawWerewolf roughly 2015 I went to one
@@Blood-PawWerewolf It was still there when I went a few months ago
Very cool video! I think as someone who doesn’t live in an earthquake zone I’m probably the target audience for this. Now I know a lot more about the intensities beyond Big Number = Scary, thanks!! :)
Those shelves have a LOT of structural integrity
I’d be very curious to see what this would look like with more accurate models for the cans. Since cans are designed to slightly nestle into each other, I would think they’d do a significantly better job staying stacked irl than they do in this sim.
Very impressed with those shelves, even the roof folded before they even tipped over 😂
Absolutely a very shocking and sobering video! I was in San Francisco in October 89 at the World Series and survived that! I was in Anchorage AK in 2004 visiting my parents when the Indian Ocean Earthquake and Tsunami occurred!!! Luckily the Tsunami alert was canceled but felt Earthquakes albeit smaller the same day! In 2018 I was in Anchorage again with the 7.0 shaker! My parents were in the 64 Great Alaska Earthquake 9.2 and survived that! I was born 4 years later in 68!
Congrats on 10K subs! you really deserve it. all of these highly detailed simulations that you spend time and work on. Love it!
It will be interesting to see the evolution of this sim software. Right now it's rudimentary but still exciting. Reminds me of the start of MetaBallStudios. Definitely subbed and keep up the good work. This is an inferesting subject.
It is getting better every week :) I have recently just started experimenting with real lighting and shadows. The simulations take more time to render it but it is worth it. I'm thinking of getting a second PC to render my work faster...
In my homestate, Connecticut; We had a intensity #4 earthquake on Apirl 5th, 2024, it's not as bad as New Jersey.
Can we appreciate how the structure of the market could resist multiple earthquakes?? Props to the engineers!
Earthquakes are so interesting to me. I've lived in California all my life, both northern and southern, so I've definitely felt some pretty major ones. The most significant recent one was a 6.4 up here in Humboldt County in December of 2022. Strangely, we had a ~6.0 earthquake on the exact same day a year prior. Wild coincidence.
Yeah! About a month ago there was a 5.5 earthquake near where I live, and so it was the first earthquake I've ever felt, even though I've always lived in California. I've heard that the earthquake drought might be ending, so keep your eye out for more.
Here in Chile, we sneeze harder than 6,4 xD
I just moved to Humboldt Co and was welcomed with that 5.5 we got a few days ago. Love it already!
Aww, I hardly felt that one at all because it was further south in Humboldt than where I live.
Since I experienced a Mercalli 7 earthquake as a kid (in Germany), my brain locks down whenever I experience another one. There have been at least 3 very noticeable earthquakes in my adulthood which I did wake up from, but every time I immediately got brain fog. My brain just got very, very slow then, I couldn't control my actions, and my subconsciousness invented some stupid excuse for the shaking. It's disappointing, actually. 😆 Must be some kind of ptsd, I guess, as back in 1992 my family found me with my eyes wide open, paralized, not responding or reacting to them. Can't remember how I got out of this state.
I think it depends more on the type of construction, in Chile and Japan they have excellent constructions. In the M8.8 earthquake in Chile (2010), collapsed buildings were one-off events and in the M9.1 earthquake in Japan (2011), there were no collapsed buildings. Both the earthquake in Chile and Japan reached maximum intensity between VIII to IX on the Mercalli scale.
Greetings from south-central Chile. 🇨🇱
Interesting, also big props to the crew resetting the 'store' each time. That was a lot of fiddly work.
Since I just found this channel I have no clue if you have addressed the fact that in the USA earthquakes in the east are very different because the rock and fault structure is very different.
I’m sorry but the physics glitch at 3:46 made me laugh kdjdkdkd that one container at the meat counter just YEETING before the earthquake even really hit kdjfkfkdkdk
What?
There was an earthquake last night. I live in Kazakhstan and thank God I’m in the countryside, but I’m so sorry for the Chinese and Kyrgyz, their buildings were collapsing
I'm so sorry to hear that. I send my prayers to your country for your safety and the lives of others.

Damn you. Take this 👍 and get out.
6:56 Ok, so the roof would be destroyed but the unanchored completely voulnrable shelves stay intact?
Exactly what I was thinking 💀
I’m disappointed but also impressed that the shelves never once tipped over. I waited the whole vid and the entire building collapsed before a single shelf tipped
5:08 look at the chairs dancing!
Lol
I would be interested to see how these earthquake sizes map across to the Richter scale.
The amount of detail is great :)
Thank you so much for saying that!
This was quite interesting! This is a neat channel, nice work with the simulations. Would have appreciated real world examples to accompany the intensity levels. Poor camera got shaken out of the supermarket at the end. Subscribed!
I think Supermarket is the safest building when there is an earthquake 😗
It seems so tough and If... when the roofs fell it probably wouldn't have directly hit us, the shelves would have held the material, then if we were buried there we got enough supplies until the rescue team came, we won't starve to death either.
The building isnt realistic in terms of strength , so you can see the damage better.
A lot of supermarkets that I've seen come across my company's desk (I work in commercial insurance) tend to be either wood frame or concrete block, which tend to be more resistant to quakes especially if up to code. I'd feel safe if caught in most strip malls during an event like these
Feel bad for whoever was in the cleaning section
@@_RKPhoenix_ “Cleanup in every single aisle”
As someone who lives in an earthquake-prone country, I can tell you that the safest place to be in the event of an earthquake is outside rather than inside a building. This is because if a building collapses and blocks the entrance and exit, it will be difficult to evacuate to another safe place, and if you are in a coastal area, there is a risk of secondary disasters such as tsunami, which will also make it difficult to escape.
Cameraman did a good job surviving all the earthquakes.
I Liked the can that flew at 8:56 . It had character
it even made sound
Can: Run!
I live in a remote city in peninsula where Level 3 to 4 happens virtually every week.
Not too long ago, launch at work cut short by Level 6.
Spending time inside door openings that are part of the load bearing walls during shakes almost became the routine.
I'm going to take a stab and guess you're in the Noto Peninsula?
A fact many people might not be aware of is that for every full step to the next number, the energy of the earthquake multiplies by 30. This means that an earthquake of 7 has roughly 900 times (30x30) the energy of an earthquake of 5.
I know this about the intensity scale, but the magnitude scale is more commonly mentioned and to some degree those obviously correspond with each other.
In one of my University geology classes, I learned that if we ever had a earthquake of 10 on the Richter scale, the tremors would be felt everywhere on earth.
Impossible. As someone who has been in an 8.4 earthquake I can assure it's barely felt in other states. A 10 would only feel in more surrounding states and in lower intensity. That's it.
@@silverendlessness4052 Earthquake intensity is exponential. The difference between 3 and 4 is bigger that that between 2 and 3, BUT WAY smaller than that between 5-6
Imagine being in Earthquake Sim Cafe when this hits, what are the odds?
This is very good! I grew up in California. Most earthquakes growing up were like a 3-4 not enough to damage, just enough to shake everything off the shelves and scare the ish out of you lol. Property damage doesn't really start until 6, from there on its gets pretty hellish. I think the simulation understated the 9 ans 10 though. You have whole buildings falling apart at that point. I was around for the Northridge earthquake, that thing was a monster and I think it was an 8 😬
I do believe it was a 6.7.
I remember the Ridgecrest earthquakes, pretty recent, only 2019. Big quake was 7.1 and caused surprisingly little damage.
An 8 on the Richter scale would correspond to about a 12 on the MMI scale shown in this video.
I can only imagine the amount of calculation going into this rendition. Amazing.thank you.
Yep! It took a whole day to calculate all this and 6 days to build the model😊
Its crazy to know that I’ve actually experienced IX shaking, it certainly looks very strong in the video
3:35 WEEEEEEEE
Wow that must have been intense. I've only experienced a III
Wow .. i survived VIII and it looks pretty strong
Just ride a wooden rollercoaster!
I only got to like 5😢
This went from a minor shake no one will see to The entire Supermarket collapses

Generally speaking, the larger the magnitude, the longer the shaking lasts and, invariably, the higher the MMI. So, here, it would have been nice to see the simulations reflect this (with longer shake times the higher the intensity).
yep! it's hard simulating more than 30 seconds. BUT I did simulate the 9.0 Cascadia quake, a 4 minute simulation on my channel :) it features a gas station
Props to the cameraman and the invisible people who survived.
You forgot the post-credits scene for 8:40…
*New message from: Boss - You coming in tomorrow?*
Just wanted to note that Turkey is an earthquake high risk country and most buildings are not built according to latest building codes. Istanbul (20 million people) and surrounding Marmara area (10 million) is expecting 7.2-7.6 earthquakes very soon. The minister of agriculture said that up to 600.000 buildings could collapse. A quick math; 600.000 x 4 floors x 2 apartments on each floor x 2 people = 9.600.000 lives in direct risk. If you live or travel to Turkey, please make sure the buildings you live/stay/work/visit are new (though new doesn’t necessarily mean resistant as there is very little audit/checks😢), have your go bag ready, be aware of tsunami dangers, look at your escape routes (look at buildings, roads etc) and research the topic endlessly. The rest of the world; please help us😢😢😢
What about marmaris?
5:15 top left “earthquakeSIM Café” what is that
I remember the Great East Japan Earthquake. I was 7 years old then. I lived Tokyo, so I didn't shaken so much (about intensity 6) but I really be scared. But many people in japan, and of course me, accustomed to feeling earthquakes. So that intensity 3 or 4, i think that is weak...
And I think in intensity 9, the racks moves more violently, and signboards on the ceiling falls.
sorry for my poor English because of I'm japanese...
I love how the fruits in the box baskets have the strongest structure on the planet and no earthquake can stop them
At 5:04 the chairs look like there dancing
They do oh my goodness
I love 3D simulations usually. I wish there were more simulations for underwater things like the depth of some oceans or even creatures. Extinct or creatures from stories. But this was great too.
6:43 caseoh does jumping jacks
This is extremely accurate
Y’know what earthquake scenario I think about fairly regularly? The Cascadia subduction zone that stretches from Alaska down to Oregon. If the whole fault was to shift at once it’d produce an earthquake of at least 9.0 with horribly devastating effect since Alaska didn’t adopt the same earthquake safety building codes that states like California have until the mid 90s.
Alaska had a 9.2 in 1964 and it was extremely devastating so I disagree about what you're getting at.
Thank you! I’ve never experienced an earthquake (and hopefully never will) people always talk about numbers, intensity and how horrible it can get but, that always seemed so unreal. Now I feel like I know more and can understand other’s experiences of earthquakes better. Thank you, and thanks to TH-cam algorithm for recommending this to me at 2am, the best time to learn new things:D
I m addicted to this videos. And the music, thanks for that too.
