The Cascadia Subduction Zone is a sleeping monster lurking just off the Northwest coast of the United States. It extends 600 miles between Northern California and Vancouver B.C. and experiences a massive megathrust earthquake every 250 years on average. The last one happened 321 years ago and scientists say there is a 30% chance we’ll see another in the next 50 years. It’s expected to rival the 9.0 quake that shook Japan for 6 minutes, which was the most destructive natural disaster in human history. It unleashed a tsunami that reached 100 feet in some areas, caused an estimated $360 billion in damages and claimed some 16,000 lives.
If this sounds ominous, that’s because it is. As catastrophic as the Tohoku quake was, Japan is light years ahead of the United States when it comes to earthquake preparedness. This grim reality has many experts very worried. And in this episode of Weathered we spoke with some of them about what we can expect when the “Big One” does hit, the kinds of work that need to be done to make our communities more resilient, and what you can do to keep yourself and your loved ones safe.
Weathered is a show hosted by meteorologist Maiya May and produced by Balance Media that helps explain the most common natural disasters, what causes them, how they’re changing, and what we can do to prepare.

When this happens, the immediate response by politicians will be "No one could have predicted this."
“Our prayers are with the people we didn’t do anything to help”
Plausible deniability 😱🤣
And political finger pointing over whose fault the lack of preparation is, who didn't respond fast enough, and stuff like that. Pretty much what happens everytime there's a disaster.
Almost all the preparedness is the responsibility of state and local government. California has been massively developing some of the most at risk areas
"Because.. You know.. The thing."
if yellow stone doesn't erupt
Cascadia: "Fine I'll do it myself"
honestly fr yellowstone is my biggest fear
@@michelleelaine799 it's not going to happen. Due to continental drift the magma plume has moved out from directly under Yellowstone.
Edit: Scishow did a video on it if you're interested. th-cam.com/video/v0c7wcpJslg/w-d-xo.html
Edit 2: yes maybe all the experts are wrong and you have uncovered "the truth" in your 5 minutes of googling the topic. Maybe the people which years of study in the field and years of researching that area specifically couldn't see what you found on a couple of websites.
Just to add, a super volcano explosion has never been linked with an extinction event.
@Александр Лазарев that's kind of the point if Yellowstone doesn't on its own Cascadia can do it for it
@@somethinglikethat2176 not only that but nasa is going to implement a mitigation solution, which is going to cool the magma chambers in 2028 which will basically kill the volcano. However certain volcanoes elsewhere are going to erupt soon, those such as Tambora, and Krakatoa which can cause worldwide devastation based on what will come out of the volcanoes

I grew up in Seaside, Oregon and we did tsunami drills in preparation for The Big One. Never once did we make it to high ground in time, and that was with the bridges intact. They told us the bridges would collapse and our odds were extremely slim that we'd survive. Great way to grow up, lol
WTFFF
Why are people still staying there? It's a 100% certainty that the earthquake will come eventually, so why don't ban people from living outside the river and move all houses? Maybe this a very european way of seeing it, I'm just genuinly curious cause sometimes I don't understand how people think in the US 🤷♀
@@freja9398 Probably American individualism :/ We tend to favor dying on our own terms over living under that kind of restriction. Also probably our capitalist mindset. It would be really expensive to ensure everyone is safe and healthy, so it's definitely not going to happen, lol. I live near Portland and I worry about the earthquake all the time. I don't think I could stand the anxiety of living on the coast!
@@freja9398 because the houses that are currently there cost a lot of money and have a great view, therefore people are unwilling to leave.
I just looked at the map. Yep. They're screwed.
the crazy thing about a magnitude 9 earthquake is that it can resonate through the *entire earth* like the on in Indonesia in 2004. That earthquake triggered other earthquakes around the world, as far away as Alaska. The power in an earthquake this size is just truly unimaginable. The 4-5 minutes of earthquake releases more energy than humans have used in their existence, including fires, actually more like 1000x more.
these are now known as planetary aftershocks. there were 2 mag sevens , 1 7.9 and i will just call it an 8 an d there are gazillions of planetary aftershocks going off all over the place .

I was at a social dinner in Astoria (population 10k). The mayor of Warrenton (pop. 8k) was talking about the efforts of installing a tsunami early warning system. Warrenton is located where the Columbia River meets the Pacific Ocean...it's basically a wetland. What he said stopped me in my tracks. The mayor said they paid a consultant to provide a study about a possible tsunami event...the not if but when event. The consultant predicted a 70% non survival rate (6000 deaths). I'm not hear to create fear. I'm yacking to heighten awareness.
As a Chilean, You guys need to prepare your infrastructure for this.
Not particularly just to resist, nono.
You have to prepare plans to get out of there. Evac routes, Safe zones, etc.
It'll come, so don't get caught lacking.
i was gonna say the same thing!! also they should begin teaching people how to behave during an earthquake, so the citizens arent completely lost in the panic when the moment arrives
I guess you would know, huh?
Most infrastructure is old buildings and houses that are not built for this. Traffic is bad. Lots will die. There is no way people would be getting to safety. The concrete is cracked everywhere. Most foundations lean, are sinking/sliding, or crumbling from age, moisture, and salt.
I helped to install tsunami warning sirens on the Washington Coast before I retired. I took part in disaster planning exercises for my employer. I now make emergency bug out bags for my family and friends as presents. My adult children no longer call me over cautious. Everyone on the Pacific Northwest Coast needs to be prepared for a disaster.
Love it. What's in your bag?
@@briangarrow448 Nice! We made an episode of Weathered on Go Bags last month. I'd love to hear what you think about it.
@@ElementalWildfire I’ll check it out. Thanks!
I just got a lahar warning siren placed at the bottom of my hill. They test it every 1st monday of the month at noon, hope the volcano doesn't decide that's a good time to blow since we pretty much ignore it at that time, but I also got a nice new shiny green USGS box placed around the corner too, think someone is watching something closely.
I'm prepared, but not sure how much it's going to help if the earthquake is huge and Mt. Rainier decides to go too......I'm right in its path, I have 22 mins to make it over 3 bridges over the White River.....and they just keep building out here, yet there is only one way out....one lane in both directions on hwy 162, yup....half of us are not going to make it, thought about a small plane but with all the ash, your not going to get far either.....I guess jump on the razor and head through the woods.
The fact that the fault is estimated to be within a mile from my house, I think its safe to say that if it hits, I'm completely screwed.
@Larry Richards people can last multiple days beneath rubble so I’m not sure about quick
@@ascendantjustice1173 bro i like your optimism

Get right my friend
Watching the end made me realize something. There really should be a new preppers show, but without the subtle mockery, ensuring there are science-based, realistic examples coupled with helpful advice. I'd definitely binge watch that.
as a california west coast born and raised, can confirm ive only ever heard this quake be referred to as "the big one" by everyone i know. all my family not on the west coast is terrified for us, and all my family here stopped caring about it bc of how many times people have falsely predicted it
You're mixing up faults! In California, "the big one" is the San Andreas fault. Different regions have their own "big one," and for the Pacific Northwest, it's the Cascadia Subduction Zone.
California's "big one" is a different earthquake than this. A different style, too - the biggest earthquakes in California are just under magnitude 8.0, although something like an 8 is possible. The one in the Cascadia Subduction Zone can be up to 9.0 or even bigger, which is more than ten times as much energy as an 8.0.
In other words, the "big one" in California is only a fraction as powerful as the "big one" in this video is talking about.
@@AyeBeAPirate "The one in the Cascadia Subduction Zone can be up to 9.0 or even bigger, which is more than ten times as much energy as an 8.0."
Except that we don't actually know. It could end up being a series of smaller earthquakes over decades.
I live in the region above the Cascadia Subduction Zone and I've heard about 'the big one' here for my entire life with warnings that it could be any day, but I've been hearing it for over 40 years now with predictions that it could happen in the next few decades to the next couple hundred years.
The predictions are never false. Unfortunately, this quake will definitely occur, but when, is always in question. 🙄
@@gailhasler8435 if youre referring to predictions made by seismographs, then you are correct- seismograph predictions are fairly accurate in telling us that an earthquake is coming. However, im talking about predictions made by people based on past events. Ive been hearing for my entire life that “the big one” will certainly strike within the next decade- theyve been saying that for at least 3 decades, therefore, those predictions have all been false.
The reality of the timing of the Cascadia fault is a game of averages. Historically, it has fully ruptured it's entire length 11 times in the last 10,000 years. And just the southern half and additional 19 times. That's once every 200-600 years. It's been 323 since the last one. So, accurate to say it COULD be any day, however it may not be for quite a while yet. The closest together they've ruptured is 150 years. The longest is nearly 1000. It's all a game of averages. That's why scientists say % chance withing so many years, rathers than specific timelines.
Turning off the gas would be the last thing on my mind while trying to run away from a 100ft wave
That advice is more for people living further from the coast. We won't need to outrun a tsunami, but we will suffer structural damage. Even a house that's mostly intact could end up with a broken pipe.
Yea, but like how they showed the house being upgraded, some of the later tips were for non-tsunami zone people. Pretty pointless to upgrade a beach house for an earthquake with a tsunami coming for you 20min later.
Even if there is no tsunami on the given area "only" a 9.0 earthquake one would hardly think on such technical details in the midst of a violent catastrophy. Although it seems to be a rational precaution.
@@BonaparteBardithion It is still valuable - can't evacuate in 20 minutes if one have to spend 10 minutes digging a family member out of the wreckage of a collapsed house
@@helium3782
Yeah, it's definitely a valuable post-quake precaution either way.
"These bridges were built before plate tectonics." Wow, that's old!
...were implemented in code because they themselves weren’t even fully understood
@@word42069 you must be fun at parties
Plate tectonics were discovered in the 1970’s, a lot of bridges predate plate tectonics
@Warlightor I was referring to the term and theory of “plate tectonics” not the physical phenomenon which it describes.
@@citetez come again
Maiya is an excellent presenter. Really does a great job speaking and presenting the info. She turned a possibly boring subject into something wayyyyyy more interesting. Just subscribed to the channel.
Wonder of that's why they used a meteorologist instead of a geologist. She probably does more speaking to the public and was the best choice they had for narration.
The only thing I don't find boring about these disasters is the death toll, lol
It's crazy to think that any of this was boring! I thought it was fascinating.
How the heck did they think we lived in a "quiet spot" when we are surrounded by mountains, volcanoes, and native history of tidal waves?

Sadly, if/when this goes off we will have politicians pointing fingers at one another blaming them for readiness or lack there of. It’s my hope that our country comes together because when Katrina hit my hometown, politicians bickered. When Texas froze last month, politicians bickered. As an American, I will answer the call if my governments fails us.
Be ready, the government tends to do that a lot

@@abelis644 Yep! He had pressing issues to attend to first, but eventually checked in with us.
In which part of the world is it called the "Fukushima" quake? Quakes are called by the location of their epicenter, thus it's commonly (and correctly) called the *Tōhoku* quake. Alternative names are known (like Great East Japan Quake) - but Fukushima isn't one of them.
You guys are doing a really great public service with this channel. The information is fascinating, accurate, and USEFUL! Thank you!
The folks who are focusing on the mega-quake of 1700 are looking at the wrong earthquake. The previous Cascadia mega earthquake was 1000 years earlier (700 AD). So it took 1000 years for the tectonic pressure to build up enough to release the energy in the mega quake of 1700.
So it’s only been 322 years since the last big one. It might take another 700 years to build up enough tectonic pressure to produce a mega quake like 1700.
There is a lot of uncertainty but I’m not concerned.
My dads been hearing it a long time. He just turned 80 and it hasn’t come.
One of the problems with evacuation is you won't be the only one running.
Thats exactly what I was thinking about the Portland area, I expect almost all of the people on that island will die.
I was gonna say Portland isn't on an island, but with the tsunami, it probably would be.

In 1964, a friend of mine was in Anchorage, Alaska during the 9.2 quake. He said that the ground rose and fell about 30 feet in waves, severely damaging or destroying almost every building. He said that the ground waves were like ocean waves, and where the ground waves hit the mountains further inland, it was total destruction. A group of people gathered on a 300 foot high bluff overlooking the beach - and they were all swept away. There are tsunami warning signs along the Central Oregon coast highway (Hwy-101) at 100 foot elevation. That isn't high enough along the bluffs next to the beach. The tsunami stays low only where it has someplace to go, like rivers and flat land. Where there is a bluff along the beach, the water pushes up the bluff. A man and his son rode the wave in their fishing boat up a river. They survived, but they landed 50 miles inland. Most of the boats were either out in the ocean, or they headed for open ocean at top speed to meet the tsunami out there. Most or all of those boaters survived. Cape Perpetua is an 800 foot high bluff on Hwy-101 near Newport. It may be named Perpetua because it was one of the few places along the Oregon Coast where people survived. Every or almost every bridge in the Coast Range mountains will be destroyed. Traffic will be completely stopped for a long time. The only transportation will be by air.
The people are not being properly warned because it would be bad for business, particularly for the land developers and realtors. If the truth about what is coming were in the headlines every day, people would be vacating the coast in droves, and tourism would stop.
My God can you imagine?

Yes, rotating is key whether at home (with cans or canning, or with packaged or dried items and with seeds too) or working at a store, always keeps things fresh.
@@razorransom1795 I was a "stocker" at a local grocery store when I was in my teens. Rule of thumb was to always rotate the stock, oldest stuff went to the front of the shelf - newest went to the back. That way the older product gets sold first. Most probably are not aware of this, if you want the "freshest" products go for the stuff in the back.
@@denyspoyner4150 um I am a stocker and yes I do know that rotation trick besides putting newer stuff underneath older so the easier to get sells faster and keeps the rotation going.😔

Yellowstone Caldera: “Hold my magma.”
The good news is that Yellowstone won't have enough magma for a super-eruption for a few thousand years, if ever. Scientists do think it could erupt again, but like a regular volcano, not the big one. The build-up to another big one would probably take lifetimes and be very well-documented and anticipated.
let's hope so
@@discoj7112 I hope u know that u are a lifesaver. I have ocd and have been obsessively think that any moment it could erupt. This eased my mind so much. Thank u
@@ellascheiderer3489 Lol
Well hey, if we get a record setting megaquake, you have to remember that the subduction zone, the faults that run from it, and the Cascades lava tubes are all interconnected like a network to Yellowstone. So if it sets off our volcanoes in the Cascades, it likely will set off some sort of event in Yellowstone too.
I lived in Seaside Oregon, and trust me there are communities that are far worst off. Some of these towns are in areas that may be impossible to evacuate and therefore everyone there would become a casualty, a great example is Ocean Shores WA due to its location on a sea-level peninsula that is made of sand.
Your former community is still pretty much screwed because the coastline will drop
oh you are entirely correct, but there are many communities that are far more screwed. My current one will be obliterated, though it isn't hard to escape the splash zone and can recover, unlike my former one. But the casualties will be massive when it happens and the environmental impact will be catastrophic. many of the towns will never recover and all that will be left are foundations buried in the sand. They will make for some very interesting ghost towns, so long as there is anything left that is.
nope just get a boat
I for one am thankful that the environment fights back against humans so we dont overpopulate and destroy the planet. Also glad i live at high altitude and dont have to deal with that
I am a geologist from Germany and made a roadtrip from Seattle to SF. We followed the coastline from the Olympic Peninsula until Astoria before we moved inland. When we arived at our hotel in Ocean Shores i told my travelmate, that we would probably be dead if the Cascadian Thrust rips apart now... Super creepy and i can't imagine living there... I read up that they need to build 17 tsunami towers. The plans are 20 years old... they have one by now. Just bizarre
If I remember right, after a large quake, the beach rose up enough to lift the abalone, rocks and critters, high and dry. The locals picked up some legal abalone for lunch and transported others and different living aquatic animals back into the ocean, now a bit further down the beach.

Thing is that you won't die, so prepare or you'll starve, be thirsty and freeze...
Living in Western Oregon, going to the beach is kind of eerie because you know that in 50-100 years, everything along our coastline will be unrecognizable. It's almost like we live on a time limit but nobody knows when the countdown ends.
Nahhhhh man. “Long overdue” in universal time means it could take another 10,000 years before those plates break free. It is almost a statistical certainty we won’t experience it. Humans may not even exist on earth anymore by the time it happens
@@yuhyuhtheindigo7085 did you not watch the video? There have been a massive quantity of these Cascades quakes in the last 10000 years. The average time between quakes is almost half of the time that it's been since the last one in 1700. I'll be surprised if I don't live to see it.
@@yuhyuhtheindigo7085 they happen on average every 250 years. It's been 320 years since the last one. Like they said we have a 37% chance of it happening within the next 50 years. .
@@joebobmarley2854 depends on who is giving the chance of it happening. Another source I heard a while back is that there is a 100% possibility in the next 25 years or so.
I would have the same feeling everytime I visited Wellington in NZ, its designed for earthquakes but it has a 8.0 potential and if that doesn't do the job the follow up tsunami might just. Christchurch was a real wake up to enjoy what it is now as it may literally be levelled at some point.
I've seen this one before, but still so amazed everytime.
Also, if a large/long tidal surge is expected, only the homes at higher elevations are less likely to be affected by a large wave of sea water. The quake itself will affect everyone within range of seismic wave activity, so the further you are inland, the better, too. Locking down and shutting off at the level of the sea, or coastal regions, is not likely to do any good at all. Just escape and evade will be your last and best resort.
Dude, I live somewhere that had a 5.5 earthquake somewhat recently, and not only was it terrifying, but it also made us realize how unprepared we really were. My mom got super paranoid and still thinks she hears an earthquake whenever a plane flies by.
The earthquakes I experienced sounded like a train as the ground beneath my feet literally rolled.
It get even scarier when you realize the Richter scale is logarithmic. A 6 is TEN TIMES more powerful than a 5. A 7 is ten times more powerful than a 6, and so on.
@@FishKepr I may have never experienced an earthquake in my life, but just reading your comment, I think that during an earthquake you probably don't even think about the numbers, during the moment, you just feel it getting stronger for every second passing by and you rush for safety and try to prepare for the aftermath.
I’ve been through a CAT 5 hurricane twice living in Florida but I am much more scared of a earthquake/tsunami living now in the pacific northwest. Very paranoid about it for sure.
@@supercoolmunkee Yes, during the earthquake you don’t really think about it. You get under whatever cover is available and ride it out. Back in HS we experienced one so minor we actually had to think if we needed to get under our desks. (We did). However, I should mention that the time to prepare for any natural disaster is BEFORE the event happens. That way you don’t stress as much on putting together a plan, you execute the one you have. Of course, no plan is perfect and you still may have to improvise.
Born and raised in Seaside, I can say it’s always wild seeing my town as an example of worst towns to live in during the big one. GO GULLS!!

06:45 A 100+ year old unreinforced concrete foundation is not going to measure up to an M8+ earthquake no matter how much you attempt to secure the building load onto it. The concrete mix 100 years ago is of poorer quality than you'd get today (aggregate back then was more often cleaned river gravel which was rounded from river erosion/friction, not the crushed gravel more often used today which has sharp binding edges).
This kind of remediation is nothing more than cosmetic. It won't help when the foundation crumbles under the seismic loading.
The best option for homes this age would be to lift the house and replace the foundation to meet current building code standards, then lowering and reconnect the house with seismic tiedowns already in situ in the new foundation.
Of course most of these houses will need to be demolished during the rebuilding phase after the earthquake. The goal of retrofitting is twofold 1) Give people a few extra seconds to get out before the building collapses (say, 25 seconds rather than 15 seconds) and thus reduce casualties overall and 2) Increase the number of buildings that are still sort of standing following the earthquake and which can serve as makeshift shelters, or can be picked through for usable food and tools, while waiting for the relief effort which could take months to get to everyone. Rescue workers will be coming in from the entire world, and it will still take months to get to everyone.
Guessing your an architect or safety consultant for building codes?
River sand is actually the good stuff, it is jagged from water/weather cycles breaking it down. We are running out of it unfortunately. Desert sand is useless because it is smooth from just wind erosion. However, I do agree. I doubt a single building will be left standing if its a full on 8-9M quake.
I'm not an architect or anything like that but that was my first reaction, that wouldn't you have to lift the entire house and reinforce the foundation instead of just adding on to it? And it made me think, wow, that would be so expensive to do, it might be better off to just demolish and start all over. But then: that's someone's home and if they could afford to do something like that, chances are they would've already done so.
It's almost like a lose-lose situation when it comes to the older buildings and homes and that's really sad.
I watched epoxy get installed from the top of a 100 year old foundation wall, only to see the epoxy ooze out of the wall 3 feet from where it was being placed. Talk about voids.

The sarcasm was so clear in this .. yet it went over their heads
"We're looking into it" is what Oregon politicians said around 2015.
The building restrictions to keep new structures out of the danger zone never lasted a year.
The schools were never relocated to a "safe zone."
One year, the money that had been set aside for study and preparation wound up getting spent on Portland promotions because the Census had determined the city to be "too White" two years in a row. (They thought that was more important.)
The only thing residents of the Cascadia zone can do is move elsewhere while they're still alive (and hope the corrupt politicians get swept away in the tsunami).
Oregon is accidentally based
Suddenly I feel no sympathy for these people.
I just looked up what you were saying about that. You either got lied to, or are lying. I suspect someone lied to you. That did not happen. There was a budget which had some money for this, the same budget completely independently had money for minority businesses. Don't confuse "there was money also for this other thing" with "money was taken from this budget"
Also, I literally just looked up an article about the new schools being opened.
@@letsburn00 I'd been following this on and off since the mid-2000s. The information is not incorrect, although I might be a little off with the years.
Their nonsense has been going on for years, and they have absolutely no concern for any of the residents.
"I just looked it up" tells me you've been completely ignorant about it all and are relying on Google searches.
Go take a valium.
They did actually move the schools around Seadide and Gearhart. It took over a decade and a lot of complaining but they finally moved the elementary, middle, and high school into a new campus built on a hill, outside the tsunami zone.
Watching this after the Turky earthquake, its kind of ironic that they suggest people doing DIY remedies to their homes to help prepare, but when it comes to the bridges that people would use to escape were 'built before plate tectonics' (no they weren't) so we're shit out of luck!
That bridge simulation is terrifying. There is a rail stop under there, stores, and more, plus two days of the week ten months of the year a market is set up under the bridge. My family is still in PDX and they worry more about me in LA than they should.
Eh.... LA has major earthquakes far more frequently than Cascadia. It is near-certain that a large devastating earthquake will hit LA in the next 50 years. It is only 1/3 likely one will hit Portland in that same period.
Yes, Portland's will almost certainly be worse than any LA has had - but it's less likely to happen in a current adult's lifetime.
In a worst-case scenario, the bridges falling into the Willamette are just the beginning of the fun. The ground under downtown Portland will liquify, the old unreinforced masonry buildings on the east side will collapse, and all of those luxe homes on stilts in the southwest hills will go sliding into the gullies. It's going to be an unbelievable mess.
I live outside Portland (used to live down in Los Angeles, so I'm familiar with earthquakes).
I really don't think this is that big of a deal for inland Oregon. yeah, if Cascadia gets a 9+, the coast is a disaster, but as the seismic waves move inland, the coastal range of mountains is going to dampen them significantly. By the time it gets to Portland, the shaking will only be a 5 or a 6. That's not that bad. It gets your heart pumping, but damage is minimal. Even if inland shaking is at a level of 7.0, that's not as bad as you think.
I think many people don't realize just how quickly seismic waves and fade out when traveling through mountains.
Most of the damage from a Cascadia earthquake will be tsunami damage in coastal towns.
I'm not worried. I only concern myself with the threat if I happen to be visiting one of the towns on the coast.
Los Angeles still has WAYYYY more to worry about in the subject of earthquakes. It's a gravel pile of fault lines down there. After living there, I realized that earthquakes are not that big of a deal. Kind of exciting actually.
@@AnonymousFreakYT the more frequent earthquakes are, the less energy they contain. The big one is overdue.
@@peterbelanger4094 The problem inland is this:
"When the next very big earthquake hits, the northwest edge of the continent, from California to Canada and the continental shelf to the Cascades, will drop by as much as six feet and rebound thirty to a hundred feet to the west-losing, within minutes, all the elevation and compression it has gained over centuries."
Many of the structures in Portland, including at least half of the Willamette bridges, will not survive that kind of force. This will also rupture the water tables, liquifying the soil and creating more instability for structures that remain standing.
There's also a smaller north-south faultline through the southwest hills that could slip as a result of a Cascadian subduction event. Portland won't get hit with a tsunami, but a big earthquake would be a catastrophe.
Japanese historical records contain a lot of information on Tsunamis and the earthquakes that preceded them, the correlation was understood going way back.
However, Somewhere in January of the year 1700 a record was made of a 16ft tall 'Orphan' tsunami hitting Japan with no earthquake preceding it.
Untill 2 and 2 were put together in the 90's and it was realized that it was caused by the 1700 Cascadia earthquake.
Just to put into perspective how massive the Tsunami could be and how far it would reach.
Oh, and these kind of Megathrust earthquakes tend to cause volcanos in the region to erupt, let's hope like the 1960 Valdivia earthquake the Big One will set one of that's not going to endanger lots of lives.
The largest volcano around us that is currently able to erupt is Mount St. Helens… last time it when off it blew a massive fucking hole In itself
The buildings in the northwest are not built to be earthquake proof!! They don't experience smaller quakes regularly like we have in California, so their building codes are fairly lax. For this reason, it is going to be particularly bad! It may not matter though, the Cascadia quake may be so large, nothing will be left standing!!!
There were also stories from the natives about earthquakes and tsunamis that were ignored b/c old timey people were racist.
@@garybulwinkle82 There is no such thing as an earthquake proof building.
Earthquake resistant, yes.
But earthquake proof, no.
@@LC-sc3en that has nothing to do with his point.
He's saying an earthquake in America had devastating effects across the ocean. Plus it could trigger volcanoes which can cause all sorts of issues.
Thanx for this
Yep, and I’ll probably be alive to see it. I’ve been through many earthquakes including the Northridge quake in CA and the one near Olympia in the early 2000s. Now I get to look forward to this one day.
I appreciate you guys focusing on Oregon! It seems like so many of these “big one” videos have a tendency to focus on places like Seattle and Tacoma, but never the Oregon coast
The last Cascadia event occurred off the coast of Oregon. So i don’t know why most don’t mention Oregon either, usually only in passing.
@@SparkyOne549 I think most of the research has been done in Washington. This stuff hasn't even been known about that long, as surprising as it may seem. The guy who discovered that mag 9 quakes were even possible along the Pacific NW figured it out in the late 1980s and the bulk of his work was in Washington.
Well, most of the production team is in Portland... one grew up in Astoria and 3 of us went to school at UO AND we love this place so much, so we're definitely biased.
@@SparkyOne549 its mentioned with cascades, but wasn't much of a focus was on it until after Japan 2011 quake with big ones earthquake wise and super volcanoes/mega caldera disasters as well. I'm surprise no one mentioned or very few caught what happened in March 2010.
@@brandonholt6717 well that and it was thought theoretically impossible till Japan 2011 showed otherwise and other ancient mega disaster sites were uncovered.
That Juan de Fuca plate that goes underneath the Cascadia has been having a series of smaller EQs lately. It's moving more, it seems.
The great california exodus is real. so are solar minimums.
That's actually a good thing. Smaller quakes means it should be slowly releasing tension rather than building up for a giant release.
When I live in Washington 😔
@@jasonforester7292 Could be, but often times smaller quakes supercede a megaquake. In fact, the larger the eventual earthquake, the higher the chance that it will have significant foreshocks.
@@jasonforester7292
Sorry. The frequent smaller quakes are mostly from the uplift & buldging of the NA plate as the subducting Juan de Fuca is caught/stuck on the leading edge and pushes it up, as per the animation.
When that subduction boundary edge/intersection slips and releases is when the real fun begins. :-/
Japan's 9.0 megaquake was preceeded by a lot of smaller quakes, and then a few ~7 magnitude quakes the week before.
Being prepared.and having a plan for both at home and at work is about the best and only thing you can do. Realize that 90% of communications/cell towers will probably be down as well.
You'll need a way to keep them charged, too...a roll-up/flexible solar panel and USB battery bank, etc.
ATMs and banking systems will most likely be out of commission, so cash & carry will be advisable.
And especially in Cascadia, an event like this will most likely trigger at least some volcanic activity as well, so it's entirely possible to be a triple-whammy.
I'm a hiker/camper, so I just keep my tent, sleeping bag, water, MRE's, and 1st Aid Kit in my vehicle 24/7, along with my bug-out backpack. I rotate/replentish the perishables every 6 months to a year if they aren't naturally replentished via hiking/camping excursions.
At this point, the entire U.S. West coast is long overdue.
Imagine being the one person who lives in that area watching this video for the first time when this happens.
It’s so surreal to listen to people talk about a horrific incoming disaster and to be mentioning cities and towns you grew up in
Growing up on the west coast my folks always told me about the inevitable earth quake and to be prepared but a 30 meter wall of water is a shocking reality check
Bit late, but it won't be quite as bad as a 30 meter wall of water. It will be a surge of water inland that rises to roughly 30m above sea level at its highest.
@@jmstheman It might, but that depends on the topology of the coastal seafloor, the shape of the shoreline, the size and direction of the quake, and the distance of the epicenter.
If it's a big, nearby subduction quake, a steep seafloor, and a V-shaped inlet perpendicular to the direction of the incoming waves, watch out! There could easily be something pretty close to a wall of water.
I bet experiencing an earthquake as a geologist is one of the coolest things you can experience, despite the impact it has on society.
kind of like storm chaser, though to be fair, storm chasers are often the first to help people and be on the scene.
As long as what happened in Italy with those seismologists doesn't occur again with the public.
Definitely. Getting lucky and seeing a wave in the road bed rolling down the street towards you at the speed of sound in rock while you're walking then having it sweep under your feet is pretty darn impressive, geologist or not. The geology mostly adds a sense of scale and directionality.
I really like Mother Nature, so even if I’m not a geologist, I do get some kind of excitement when experiencing these things. I’ve only experienced earthquakes, volcano eruption and a tropical storm.
As a resident of the Pacific Ring of Fire, I can confirm it is both cool and scary. And a humbling experience too...

California isnt really at risk for a 9.0 though, the san andreas is a strike slip type of fault where the plates pass by each other in opposite directions rather than colliding or pulling apart. The biggest prediction there is around 7.0, obviously still serious and needing prep, but because the scale is exponential, the damage would be nothing close to a 9.0.
@@jordanw1649 Bay area, but things are expensive as hell here
@M Muss Most houses are single family wood frame homes and they do really well during earthquakes. My house had 0 issues during the Seattle 2001 quake that was 6.8. Some 7000 houses were damaged in the 1994 LA quake so it is hard to know for sure.
Great video!
Can’t remember the name, but there is a documentary about Japan building a tsunami wall for a village that had been destroyed. After it was built, folks realized that the wall killed the village. They’d survived a tsunami loosing everything, but it was the over reaction afterward, building this wall that destroyed their businesses, seafront property, and eventually the entire town just moved away.
Pro tip: Keep supplies in your vehicle, like a hiking backpack and food. Maybe walking shoes too. The roads are going to be gone.
And long pants so that you don't get scratched every time you weave through plants and tall grass.
And even if the roads survive, there’s going to be so many fallen trees. It will be a mess

As a person that lives in the New Madrid fault's effected area I'm always a little relieved when it gives a little jiggle as I know it's letting off stress and not getting ready to make the Mississippi flow backwards again
I live in Missouri but raised in Los Angeles. One day pumping gas I told my husband we just had an earthquake, he said no we didnt turned on car radio and boom they said we just had a 4.0 in the Madrid. Everytime I say hey were having an earthquake he listens as does my daughter and son in law. None have ever been in one. I remember bouncing on a bed as kid cause we got hit suddenly by a 7.0
I live along that fault also, and its wild. It actually runs under my old high school at one point and I'm just like "Ya'll should probably build a new one somewhere ELSE?"
I grew up on the New Madrid. It would rumble and rock some pictures or glasses every now and then, but we knew it was there and its history. We knew what it had done in the past but didn't worry too much about it. What can you do about a fault line??
@@TheMombass Um, move? At the least double-check exactly where it runs in relation to your house. I've seen photos of homes built actually straddling the San Andreas fault in California--it could be seen because this was inland, in a basically desert area. If the earthquake happens in that spot, your house will be split in two.
@@elainechubb971 There's risks everywhere. The biggest risk for most ppl isn't even on any maps they have access to - oil, gas, and diesel pipelines. An awful lot of ppl only found out their house was on top of a pipeline when it started leaking or burst. And pipelines leak a lot more often than natural disasters come through town.
I only live a couple miles from the Bakkan Pipeline (DAPL is what they called it in the Dakotas). They had multiple leaks in the first year of operation. Meanwhile, the last big tornado to come through our town was in the 1970s and the last time we felt an earthquake was the big earthquake from the New Madrid fault - and I live in Iowa.

The worst earthquake I experienced as a kid growing up in So Cal was while I was kneeling beside my motorcycle working on it while it was on the center stand. It started rocking back and forth and almost fell over on me before I could scramble out of the way. It is very unsettling to feel the Earth beneath your feet shake. I left CA when I turned 18 and haven't lived there since.
Great video
I live two blocks from the San Andreas fault line, one of the longest fault lines in this part of the world. Been through a number of quakes including the 1989 Loma Prieta quake. All you can really do is have a plan and prepare to be without water, power, and access to food for a few days to weeks. It’s really as simple as having batteries, water, non-perishables, clothes, water filtration, blankets and first aid packed and ready to go at a moments notice in a go bag. Have more than one (one in car, one in house) as some structures would not survive prolonged shaking or you may need to move to safer ground away from home. The Loma Prieta quake was only 17 seconds, I can’t imagine 2+ mins as experienced in Japan or South America has gone through.
