Thank you. I've known the basic idea for years. Long ago I read an account of someone who slept near the beach and woke up underwater - trying to figure out which way was up. Learning some geology, it's clear by looking at the islands where there were landslides and where there will be ones in the future. But your work adds detail and communicates with many people. Keep up the good work.

You're not talking about the waves in the rest of the Pacific Ocean? There will also be waves in Japan, Chile, Mexico, the Philippines, Papua New Guinea, New Zealand, Samoa, Peru, the Solomon Islands, Taïwan, Kamchatka and other places ...
@@samohtt The colossal tsunami waves that are coming will decimate Moscow, the entire Arctic, the Bering Straight, Alaska, the entire Atlantic, the entire Pacific, Drake Passage, the Indian Ocean and the entire Antarctic ... the Panama Canal, the Suez Canal, the Red Sea, the Persian Gulf, the Mediterranean Sea... and most elevations below 2,000 ft... including the calderas, volcanic islands, etc. In other words, colossal tsunami waves will decimate our entire world because when the first Antarctic ice shelf collapses, the glaciers above it will slide into the sea which will displace massive volumes of sea water which will launch colossal tsunami waves that will displace the other Antarctic ice shelves which will result in the other Antarctic glaciers sliding into the sea which will launch thousands of catastrophic tsunami waves that will race all across our Earth in under 24 hours. The decimation is expected to go on for months as the continents are inundated by huge tsunami waves while thousands of volcanoes explode - thousands of cities will be buried by the ash as sea levels rise - few survivors are expected.
But the cracks are starting to link up. A like, 90 foot chunk already broke off earlier this month. I'm curious but SERIOUSLY not curious what it's going to do next... This is an apocalypse sized wave and it's completely feasible for it to happen while all of this activity is going on :(
Kevin Burns - Where exactly did this 90 foot chunk fall off from? If you watch this, it ignores that there have been NO active volcanoes on Oahu in recorded history. It doesn't pinpoint this as beginning on the Big Island, but on Oahu, of all islands!!
Canary islands could do the same thing for the East coast. Cumbre Vieja. When you get to the “once in a million years” probability range, there are oh so many things to worry about. Mega tsunamis are just one of them.
As the wavefront expands outwards, the energy is spread out over an increasing area. The initial wave height will reduce down correspondingly as the circumference grows.
As terrifying as it is to contemplate meeting the face of one of these tsunamis, it's even more horrifying to imagine being on the island side, considering that the troughs following the departing waves appear to reach, in the beginning anyway, to the bottom of the ocean.
If anyone is curious, 2*10^20 Joules is equivalent to about 48,000 Megatons of TNT. That’s like setting off 1,000 Tsar Bombas (the 50-Megaton thermonuclear bomb which set the record for largest man-made explosion ever) all at the same time. It’s a lot of energy. So even if “only” 10% of it went into forming the waves, that’s still nearly 4,800 Megatons of TNT or 4.8 trillion pounds of explosives set off at once.
We have to add here, that is is not all at once (less than a millisecond in case of a thermonuclear explosion) but stretches over tens of seconds to minutes, and is not concentrated on one point but across several kilometers. But still, it is an impressive amount of energy released "just" from some rocks sliding. i would love to see a high quality 3d animation of such an event with the point of view a person has standing on the tip of the mountain just behind the place where the slide occurs. it must be an overwhelming spectacle.
This event is something you want to see in simulation and not as an actual event. Even with warning, the loss of life and property will be horrific. You can almost foresee an event in 500+ years where mankind has made some progress against sea level rise only to have it all overtopped by this tsunami.
It's May 16, 2018. The part of Kilauea that he is talking about is right at moment trying to tear it self off the mountain. About 20 fissures heading pretty much in a straight line for the west to the sea. I live on the east coast of USA in what is called The Low Country. What would computer sim. show for La Palma slide ?

Kevin McManus, this video proves nothing except that somebody made some cool looking animations and inserted some suppositions. I can maybe be sold on underwater landslides, but the height of the supposed tsunamis is a stretch.
Michael H Lol what are you basing your disbelief upon? Simply that you can’t comprehend the large numbers involved? Do you also believe the earth is only 6000 years old? Look at the size of that debris NE of Oahu in Google Maps. It is absolutely gigantic, every bit as big as he said. It stretches 200km into the sea! That is absolutely mind blowing. I can’t comprehend a landslide SO huge that it scatters debris 200km away. But clearly it happened. So with a displacement on that scale, I will believe practically any height of tsunami!
Michael H I guess the meteor that caused the extinction of the dinosaurs only had a wave that was 200 feet tall if you want to fact check these statements youre more than welcome to
@@michaelh7538 Take a loot at the wave that was created in Alaska in 1958 by the Lituya Bay earthquake/land slide. The backslide creates a huge wave. If you can find the location on Google Maps you can still see the treeline at 200' where it wiped the landscape. The story about the guy and his kid in the harbor when it took place is worth reading. The wave took there boat for a pretty wild ride up and over the island that is at the mouth of the bay.
@@Syclone0044 There's still no way of knowing how long a landslide tsunami can maintain its energy across the open ocean. From most of the events I've looked at, it seems that they lose their strength much faster than seismically generated tsunamis.
I've seen a lot of crash analysis / simulation in my day...never geology but your models are based on solid observable data and the work looks very solid as well. Great job and...thanks for the nightmares.
2:40 I'd really like to see an accurate depiction of the steepness of the topography of the island from the top of the island down to the sea floor constructed with real proportions of height and width. I can't fathom (pun intended) the true dimensions of the event in that squeezed, vertically exaggerated, version shown.
Keep in mind Mauna Loa on the big island of Hawai’i is the tallest mountain on earth by a substantial margin beyond Mt Everest (29,000ft) if you measure its Prominence - the height it protruded up from the base level of the surrounding Earth’s crust. It’s something like 45,000 ft high.
Anyone who ever made sand castles as a child know what happens when you make the sides of your sandcastle too high. They slide off. But they make a wider base that supports the next piles of sand you put on top of it. The only thing is the Hawaiian islands are on such a larger scale in 16,000 feet of water.
Excellent simulation, but to really have an impact you need to show how it would affect populated areas. How far inland would it go in Los Angeles or San Francisco or Seattle? Would it wash over Panama and into the Caribbean? What would the effects be in Japan, China and the Philippines? And perhaps more important, what are the odds of it happening in the next century?
Iafiv Iv more like 10s of millions, there is no escape, 4 hours warning will cause mass hysteria, traffic jams, it will come inland many miles, west coast kiss your ass good bye, lol
Leo Verran yep, this would pretty much obliterate the entire west coast of North America. I am sure it would reach many miles inland in plenty of areas and then cause cataclysmic flooding as that water flows naturally downhill (not simply back the way it came).
Answers to all those questions are documented in historic records, along with the exact date of this horror - written in different languages by people more then 16,000 km apart.
What would happen in San Francisco Bay during such an event? How high in the bay would the water rise? Would it swamp, say, the Dumbarton bridge? which is a rather low bridge over shallow water in the S Bay.
Katy Williams I think you'd be better off heading to high ground on the peninsula than trying to escape over a bridge in such a scenario. That's what I'd do anyways.
Huh?!...at 0:54 in the video it talks about "Over the past 20 million years...", yet just previous to this a time line showed the oldest island, Kauai is only 5,100,000 years old...huh...what gives here!?
Those ages are the time at which the island broke off from the super island and became their own island. Of course Kauai didn’t exist until it became its OWN island, but the main giant island from which all of them succeeded was around long before that.
Yes in a word. Does it not make you wonder about the massive drills being done in Seattle & Vancouver recently for just this & then Arizona doing a million plus person drill on what to do when a catastrophe happens on the west coast & all of California ends up on your doorstep? Kilauea could trigger the Cascadia & Juan de Fuca then it rolls across the Fracked & broken N. American Crayton activating the San Andreas, then the New Madrid faultline, and everything in between. Haven't people in USA also wondered why their infrastructure is being permitted to crumble & decay as it is rail roads, bridges, even in NYC & L.A. rusted & ruined but we see no big refurbishing, retrofitting, updating projects going on as they should as quakes mount in both activity, size & frequency. See Gordon Michael Scallion Future Map of America. WOW
I wonder how quickly a full-scale evacuation of the entire West coast of North America would take. Probably more than the 4 1/2 hours the tsunami takes to get there :/
Except landslide tsunamis have very limited endurance due to their much smaller size. When a megathrust tsunami is generated, hundreds of miles of ocean floor are shifted, displacing far more water than a collapsing mountain does. Yes, landslide tsunamis are higher, because all that energy is concentrated in one spot. But they don't go nearly as far for the same reason. Any tsunami generated by Hawaii's volcanoes will be a local event, affecting only the archipelago itself. If anywhere else in Polynesia, let alone around the Pacific basin, sees any runup at all, it'll be laughable.
+AtarahDerek The Krakatoa tsunami was caused by pyroclastic flow, which is a slide of hot ash and gas. It is less dense than landslides and has less volume. Though they do destroy buildings, they have less kinetic energy than landslides.
The landslide was scattered over more than 9000 square miles of seafloor. It traveled its last 85 miles uphill a thousand feet. If that's any help. It reached a top speed of 100 meters per second. There is no geological evidence of a large tsunami from that time period.
It’s absolutely wild thinking about all to these huge events happened long before all of us and we still are able to come up with detailed accounts of them . Also it makes you wonder you hear of all of these world altering events and we haven’t had one in so long. Very curious as to what the next one will be and when
Great video. I'm surprised ingomar200 didn't mention the Koolau Mountains. I may be wrong, but I think the Koolau Mountains are the western remains of a huge volcano on Oahu. Maybe the slide was so large, it took out 12 o'clock to 6 o'clock. This doesn't contradict the middle phase. The weight of half of this huge volcano probably contributed to the slide. I think the Koolau Mountains are just stunning in the clouds when it rains. Finally, ingomar 200's last line is rather strange. I'd rather have no tsunami than one later. The destruction will be mind boggling. Even Eastern Asia will get its share. Every coastline around the Pacific will be wiped out. But I guess it will someday happen, just like the slide in the Canary Islands will take out the entire coastline of the Atlantic.
When you look out from the Pali lookout, you're looking out at the remains of the Koolau volcano caldera after the slide. The steep cliffs on that side are the heavily eroded western sides of the caldera and Kaneohe Bay is the caldera bottom, so yes, half of the volcano slid off into the ocean. This is different from the steep cliffs of Molokai which are where the great crack was when the northern side of that island slid off. High, steep ocean-front cliffs in the islands like that are usually indication of the location of a major slide. Kalaupapa on Molokai is the product of secondary volcanic activity after the great Wailau slide. That's why it is a somewhat odd projection from the cliffs.
Pretty interesting that you can literally see the collapse of the other islands on satellite. But what you're saying may be correct, but knowing the size of the wave is tough. What i take from this is there is just another thing to be wary about living on the west coast.
You posted this almost 2 years ago how did you know about all this? Where does your research come from on the most recent transgression in Hawaii? Where do these scientists consider this to come from?
It's called the "Hilina Slump". See link: __ en.wikipedia.org/wiki/Hilina_Slump __ Robert Roy Britt wrote about it in December, 2004. See link: __www.livescience.com/3753-megatsunami-modern-threat.html
Those colossal tsunami waves decimated California, Oregon, Washington, British Columbia and Alaska - if you want to see the decimation, I can forward to you the old maps so you can see it with your own eyes.
Those colossal tsunami waves created the Bay Area of California, the Sacramento and San Joaquin Valleys, Truckee Valley, Lake Tahoe, Snake River Valley, the Great Salt Lake, etc. Lake Tahoe has dozens and dozens of rivers flowing into it from the mountains - that's why it's not salt water anymore. The tsunami waves went all the way to Hudson Bay and decimated all of Alaska.
The Great Salt Lake, you say? That was impressive, considering the tsunami waves were ~100 m and the surface of the GSL is over 1280 m above sea level. Not to mention the waves would have had to cross the Sierra Nevada and the entirety of the Great Basin.
~100 m you say? That's impressive considering geologists estimate the tsunami waves at over 700 m where they began - go ahead and do the calculations. The elevation of the GSL was not at 1280 m when the cataclysm happened and the Sierra Nevada's weren't there either - this makes all your mental blocks to the facts simply irrelevant. You've got unsubstantiated theories that crumble to nothing. I've got hundreds of independent historic documents - written by people who observed the decimation with their own eyes. Who do you suppose wins this debate? The Doctoral Scholar with decades of research and thousands of independent sources - going back over 600 years, handwritten in Chinese, Japanese, Portuguese, Spanish, French, Italian, Greek, Latin, Hebrew, Arabic, Dutch, etc., or maybe it's the guy with theories that wins this stand off. How would the Chinese and Japanese know anything about the January 1700 cataclysm? They had hundreds of ships out in the Pacific, sailing along the coasts of North America - before, during and after the cataclysm. There's no way land can rise up over 1280 meters in 300 years? Wrong again. You've got your theories though, you've got your fake science gods with the IQ of 11 year olds - so you're good to go, right? The Great Salt Lake is not nearly as much of a stretch as the Hudson Bay that I mentioned - that was one of the most incredible surprises found in the historic documents, along with several others.
One more major landslide coming off the big island and the Great Crack will probably go, which will launch huge tsunami waves that will bring down the Chain of Craters, which will launch even bigger tsunami waves that will bring down the Kilauea crater which will launch even bigger tsunami waves that will bring down the southern half of Mauna Loa which will launch even bigger tsunami waves that will decimate almost all of the Hawaiian islands which will result in about 100 million cubic kilometers of debris racing down the lava rock slopes which will launch even more colossal tsunami waves that will decimate the West Antarctic Ice Sheet - which is approximately 25 million cubic km of ice - while the France-sized Ross Ice Shelf with its billions of tons of glaciers is also decimated which means colossal tsunami waves will race all across the Earth as life as we know it comes to an end.
why do you say the south side of Kilauea will have the slip (and portray it as such) and then show the Tsunamis main direction to the North East? You did so well until just at the end. Then it became obvious that you are actually hoping this happens but you aren't sure what it looks like
This kind of megatsunami, several 100 metres in height, would it limit itself to the shores of the Pacific? Would it not, I should fear, affect the whole Planet, including the two other Oceans, the Indian and the Atlantic? I guess there would be a terrible loss of lives not only in the coastal areas, but far, far inland. Maybe the flood of Noah was such an event. Any case, could you please make an animation what such a wave (500 metres high) would do to all coastal areas of the World?
There is no evidence for Noah's alleged flood. Bronze age people did not even know about the new world, Oceania etc. If you think a kakapo (flightless parrot) walked and swam 12,000 miles to get on a boat with millions of animals, plants, and food, you are a nut.
Know that Noah's flood is a myth. I meant of course, one or more events that could have been the origin of the myth. There are some indications of such happenings, like the filling of the Black Sea, filling of the Persian Gulf, the Northamerican ice sheet breaking, causing enormous flooding out in the Atlantic. " If you think a kakapo (flightless parrot) walked and swam 12,000 miles to get on a boat with millions of animals, plants, and food, you are a nut. " I guess it is you Assuming things about me that absolutely aren't true!!!
Real floods could have generated the many worldwide myths, one of those myths being "the flood of Noah". I don't think that way at all which you propose and calling me a nut --- you assumed I was thinkiing a certain way and calling me a nut --- that is insulting. Now, there is science about natural phenomenon AND there is also research about myths and their history.
If you look at the future slide area they outlined on the Big Island west of Volcano, there is a crack forming in the area where the predicted slide could take place. It looks like a black line. I thought it was a collapsed lava tube but apparently it is 100 feet deep in some places and 20+ yards across.

Answers to all those questions are documented in historic records, along with the exact date of this horror - written in different languages by people more then 16,000 km apart.
Will the waves be smaller in San Francisco?
Sonia Zamora Yes. Max would be like 30m
This happened hundreds of thousands of years ago
The area of the big island referred to in this is known as the helena slump, it's moved several feet per year for a while now. Only a matter of time.
What would happen in San Francisco Bay during such an event? How high in the bay would the water rise? Would it swamp, say, the Dumbarton bridge? which is a rather low bridge over shallow water in the S Bay.
Katy Williams I think you'd be better off heading to high ground on the peninsula than trying to escape over a bridge in such a scenario. That's what I'd do anyways.
If this was made by a animating software, ok. But if this was made by an automatic animator or something, whats the name?
Huh?!...at 0:54 in the video it talks about "Over the past 20 million years...", yet just previous to this a time line showed the oldest island, Kauai is only 5,100,000 years old...huh...what gives here!?
No, that age is the last time there was a landslide from Kauai that caused one of these mega tsunamis.
NO, THATS THE AGE OF KAUAI
I assume he means the older, submerged or almost submerged islands like Midway as part of the island chain.
Those ages are the time at which the island broke off from the super island and became their own island. Of course Kauai didn’t exist until it became its OWN island, but the main giant island from which all of them succeeded was around long before that.
Is this happening now? May 2018
imguevara09 that would be unreal but doubtful.
imguevara09 exactly its going on now
Yes in a word. Does it not make you wonder about the massive drills being done in Seattle & Vancouver recently for just this & then Arizona doing a million plus person drill on what to do when a catastrophe happens on the west coast & all of California ends up on your doorstep?
Kilauea could trigger the Cascadia & Juan de Fuca then it rolls across the Fracked & broken N. American Crayton activating the San Andreas, then the New Madrid faultline, and everything in between.
Haven't people in USA also wondered why their infrastructure is being permitted to crumble & decay as it is rail roads, bridges, even in NYC & L.A. rusted & ruined but we see no big refurbishing, retrofitting, updating projects going on as they should as quakes mount in both activity, size & frequency. See Gordon Michael Scallion Future Map of America. WOW
News & Views Today kilauea couldn't trigger any faults because its thousands of miles away from any faultline. Its a hotspot.
News & Views Today Won't get infrastructure projects from a Republican Government - they think thats a nasty liberal idea.
scary as hell
Imagine that wave i this year or in the future?
@@legoguy004davidson6 could happen any time
where is the kilauea runup charts?
What music is this?
20 million years ago? How did you arrive at that number other than a wild guess?
I wonder how quickly a full-scale evacuation of the entire West coast of North America would take. Probably more than the 4 1/2 hours the tsunami takes to get there :/
I love the choice of music, did you put 4’33” in here?
So how many miles were covered in water on the west coast? Is that 100m run ups in ocean only? what about terrain?
which simulation software is used here?
What software did you use to make these animations?
what is the soft you are using???? can u do a simulation for 51.685997041545214, 2.486757603703606
This is awesome, Kaena used to be above water too , it is its own volcano apart from MT kaala/waianae range
The thing is though waianea eroded instead of collapsed
5:06 Alternative end: "Are you prepared to die?"
In Apocalypse Earth you do not go to your watery grave. Your watery grave comes to you! lol
What simulation did you use in this video?
Except landslide tsunamis have very limited endurance due to their much smaller size. When a megathrust tsunami is generated, hundreds of miles of ocean floor are shifted, displacing far more water than a collapsing mountain does. Yes, landslide tsunamis are higher, because all that energy is concentrated in one spot. But they don't go nearly as far for the same reason. Any tsunami generated by Hawaii's volcanoes will be a local event, affecting only the archipelago itself. If anywhere else in Polynesia, let alone around the Pacific basin, sees any runup at all, it'll be laughable.
could you be kind enough to cite some sources, I'm really interested in the topic, thanks!
Good point. Let's hope that the landslide isn't the result of a big quake, however....
+AtarahDerek The Krakatoa tsunami was caused by pyroclastic flow, which is a slide of hot ash and gas. It is less dense than landslides and has less volume. Though they do destroy buildings, they have less kinetic energy than landslides.
Any studies to prove what you're saying?
Have you tried to do it in Delft3D, MIKE 21 or SWAN?
The landslide was scattered over more than 9000 square miles of seafloor. It traveled its last 85 miles uphill a thousand feet. If that's any help. It reached a top speed of 100 meters per second. There is no geological evidence of a large tsunami from that time period.
It’s absolutely wild thinking about all to these huge events happened long before all of us and we still are able to come up with detailed accounts of them . Also it makes you wonder you hear of all of these world altering events and we haven’t had one in so long. Very curious as to what the next one will be and when
science
What software is this??
What program do u use
Which model was used for this computation and graphics generation???
any chance you could do another one in feet, instead of meters for us Americans that refuse to convert? Y
Why would you use feet?
:)
Lazy Americans
How tall would the waves be when they hit Maui Island and how much time before they hit?
This happened hundreds of thousands of years ago
Great video. I'm surprised ingomar200 didn't mention the Koolau Mountains. I may be wrong, but I think the Koolau Mountains are the western remains of a huge volcano on Oahu. Maybe the slide was so large, it took out 12 o'clock to 6 o'clock. This doesn't contradict the middle phase. The weight of half of this huge volcano probably contributed to the slide. I think the Koolau Mountains are just stunning in the clouds when it rains. Finally, ingomar 200's last line is rather strange. I'd rather have no tsunami than one later. The destruction will be mind boggling. Even Eastern Asia will get its share. Every coastline around the Pacific will be wiped out. But I guess it will someday happen, just like the slide in the Canary Islands will take out the entire coastline of the Atlantic.
When you look out from the Pali lookout, you're looking out at the remains of the Koolau volcano caldera after the slide. The steep cliffs on that side are the heavily eroded western sides of the caldera and Kaneohe Bay is the caldera bottom, so yes, half of the volcano slid off into the ocean. This is different from the steep cliffs of Molokai which are where the great crack was when the northern side of that island slid off. High, steep ocean-front cliffs in the islands like that are usually indication of the location of a major slide. Kalaupapa on Molokai is the product of secondary volcanic activity after the great Wailau slide. That's why it is a somewhat odd projection from the cliffs.
waianaie area looks like a washed out caldera also.
Pretty interesting that you can literally see the collapse of the other islands on satellite. But what you're saying may be correct, but knowing the size of the wave is tough.
What i take from this is there is just another thing to be wary about living on the west coast.
Where can I buy the audio book?
Run 200 kilometres underwater? Wouldn't ocean bed friction have halted it much sooner?
You posted this almost 2 years ago how did you know about all this? Where does your research come from on the most recent transgression in Hawaii? Where do these scientists consider this to come from?
It's called the "Hilina Slump". See link: __ en.wikipedia.org/wiki/Hilina_Slump __ Robert Roy Britt wrote about it in December, 2004. See link: __www.livescience.com/3753-megatsunami-modern-threat.html
what font is used here?
It is said that Costa Rica is expecting "a big one". Where wpuld a tsunami hit if it happens?
What was that
What?!?! 100 meter run ups all the way on to North America?!?! You have got to be kidding me!!
How far will that go? Maybe to the very east of California, or halfway into Nevada.
Those colossal tsunami waves decimated California, Oregon, Washington, British Columbia and Alaska - if you want to see the decimation, I can forward to you the old maps so you can see it with your own eyes.
Those colossal tsunami waves created the Bay Area of California, the Sacramento and San Joaquin Valleys, Truckee Valley, Lake Tahoe, Snake River Valley, the Great Salt Lake, etc.
Lake Tahoe has dozens and dozens of rivers flowing into it from the mountains - that's why it's not salt water anymore. The tsunami waves went all the way to Hudson Bay and decimated all of Alaska.
The Great Salt Lake, you say? That was impressive, considering the tsunami waves were ~100 m and the surface of the GSL is over 1280 m above sea level. Not to mention the waves would have had to cross the Sierra Nevada and the entirety of the Great Basin.
~100 m you say? That's impressive considering geologists estimate the tsunami waves at over 700 m where they began - go ahead and do the calculations. The elevation of the GSL was not at 1280 m when the cataclysm happened and the Sierra Nevada's weren't there either - this makes all your mental blocks to the facts simply irrelevant.
You've got unsubstantiated theories that crumble to nothing. I've got hundreds of independent historic documents - written by people who observed the decimation with their own eyes. Who do you suppose wins this debate? The Doctoral Scholar with decades of research and thousands of independent sources - going back over 600 years, handwritten in Chinese, Japanese, Portuguese, Spanish, French, Italian, Greek, Latin, Hebrew, Arabic, Dutch, etc., or maybe it's the guy with theories that wins this stand off.
How would the Chinese and Japanese know anything about the January 1700 cataclysm?
They had hundreds of ships out in the Pacific, sailing along the coasts of North America - before, during and after the cataclysm.
There's no way land can rise up over 1280 meters in 300 years? Wrong again. You've got your theories though, you've got your fake science gods with the IQ of 11 year olds - so you're good to go, right?
The Great Salt Lake is not nearly as much of a stretch as the Hudson Bay that I mentioned - that was one of the most incredible surprises found in the historic documents, along with several others.
When will this happen, ?? Can't wait to see it any longer
This happened hundreds of thousands of years ago
What's the music called anyone?
Are there any human beings around at that time?
i"m pretty sure that simulation shows that the whole volcano will fall into the ocean. By Kilauea do you mean Mauna Loa?
One more major landslide coming off the big island and the Great Crack will probably go, which will launch huge tsunami waves that will bring down the Chain of Craters, which will launch even bigger tsunami waves that will bring down the Kilauea crater which will launch even bigger tsunami waves that will bring down the southern half of Mauna Loa which will launch even bigger tsunami waves that will decimate almost all of the Hawaiian islands which will result in about 100 million cubic kilometers of debris racing down the lava rock slopes which will launch even more colossal tsunami waves that will decimate the West Antarctic Ice Sheet - which is approximately 25 million cubic km of ice - while the France-sized Ross Ice Shelf with its billions of tons of glaciers is also decimated which means colossal tsunami waves will race all across the Earth as life as we know it comes to an end.
Whirled Publishing Fearmonger.
what’s the song?
I heard a pin drop!!! Woah crap! Where'd it go?
Woah! Surfs up dude! :)
Could you simulate the toga super volcano?
what did you use to simulate this
This explains why the sand was transported so far inland on Maui. The sheer volume is almost unfathomable!
People keep talking about background music, but I don't hear any?
Any idea how tall the wave would be if it hits Oahu? Just having a bit too many tsunami dreams recently🫣
Sound Really Helped. Thanks.
I CAN'T BELIEVE HOW BIG IT WAS
imogar what name aplikasion?
Anybody know the bg music title pls? 🥺
why do you say the south side of Kilauea will have the slip (and portray it as such) and then show the Tsunamis main direction to the North East?
You did so well until just at the end.
Then it became obvious that you are actually hoping this happens but you aren't sure what it looks like
How about krakatoa?
What would happen if a chunk of the Big Island collapses?
WEEEEEEE
This kind of megatsunami, several 100 metres in height, would it limit itself to the shores of the Pacific? Would it not, I should fear, affect the whole Planet, including the two other Oceans, the Indian and the Atlantic? I guess there would be a terrible loss of lives not only in the coastal areas, but far, far inland. Maybe the flood of Noah was such an event. Any case, could you please make an animation what such a wave (500 metres high) would do to all coastal areas of the World?
A L. You are right on the money. Anytime now.
There is no evidence for Noah's alleged flood. Bronze age people did not even know about the new world, Oceania etc. If you think a kakapo (flightless parrot) walked and swam 12,000 miles to get on a boat with millions of animals, plants, and food, you are a nut.
Know that Noah's flood is a myth. I meant of course, one or more events that could have been the origin of the myth. There are some indications of such happenings, like the filling of the Black Sea, filling of the Persian Gulf, the Northamerican ice sheet breaking, causing enormous flooding out in the Atlantic. " If you think a kakapo (flightless parrot) walked and swam 12,000 miles to get on a boat with millions of animals, plants, and food, you are a nut. " I guess it is you Assuming things about me that absolutely aren't true!!!
I assumed nothing, YOU brought a mythical flood into a scientific discussion.
Real floods could have generated the many worldwide myths, one of those myths being "the flood of Noah". I don't think that way at all which you propose and calling me a nut --- you assumed I was thinkiing a certain way and calling me a nut --- that is insulting. Now, there is science about natural phenomenon AND there is also research about myths and their history.
If you look at the future slide area they outlined on the Big Island west of Volcano, there is a crack forming in the area where the predicted slide could take place. It looks like a black line. I thought it was a collapsed lava tube but apparently it is 100 feet deep in some places and 20+ yards across.
What about the Azores? They show signs of a crack in the middle of the island,which may cause a big land slide any time soon
Vocal would be helpful, color blur's script.
Beautiful model. Thanks for posting.
please do the molokai landslip and mega tsunami.
Excellent work.
Does Anyone Know The Name Of This Song?
😆
you should really put some sound, i thought my speakers where broken
Considering the goings on at the big island right now. This could be a few months from now.
I love it! Thank you!
I see the TH-cam algorithm is in full effect.
why do i binge watch these vids
Me: ahhhh tsunami!!!
Tsunami: Bruh I can eat you
Very cool
Getting no soundtrack here. Everything is on, so I dunno
