- In 1958, an earthquake-induced rockslide into Lituya Bay (Alaska) carried and pushed water up to an elevation of 523 meters. This splash is often referred to as the "World's Biggest Tsunami". Whether splash or tsunami, the Lituya Bay landslide and wave are remarkable geophysical events. This movie is a physics-based simulation of these happenings as constrained by the best available information. See a scientific paper here...

Good video. Nevertheless, I prefer 523 meters in an uninhabited area rather only 5 meters in an inhabited area. RIP all tsunami victims.

Palu 4-7 meter high Tsunami: Let's agree to disagree
Although the water reach more than 500+ meters but the magnitude or the power of this tsunami is very small and short, typical a landslide tsunami only large at local place.
@@wateroceanwaves6025 It didn't reach 500 meter though
It was just a splash
@Mingo .. whether it was 500m or not .. nor whether it was tsunami or splash .. was not a good day to be in .. that bay .. can we agree on that?
@@Toppradd yeah, but we talked about 'tsunami science', The magnitude of Lituya Bay tsunami is still small compared to Indian Ocean 2004 and Japan 2011, typical a landslide tsunami, extreamly large at local and short period and it occured in a 'narrow bay', that's why it was very tall. If it happened in open ocean, that would be a small tsunami.
Hard to believe one father and son in a boat actually rode one of those out and survived. Seems impossible.
Yes very remarkable there are clips out there with them telling their story. Typical "small town" people, very quiet and laid-back like it was no big deal lol
What is this?
@@86_percent28 what is what?
God was with them
He's Noah my guy
So a Megasplash.
Technically it was the initial splash that reached 1700 feet... still an incredibly amazing sight to behold... the waves it produced were obviously not that large but still enormous and devastating. Gotta love mother nature and it’s unstoppable, pure destructive forces and it’s absolute peaceful, calm and quiet times!!!
@@tia3883 nah. Splash is splash.
@@ImAmirus so you are the smart ass here huh?
Any peer review papers release yet sir?
@@tia3883 no? lol
Just imagine you were at the top of the mountain (the smaller one on the other side of the slide) and you saw a huge wave almost come and wash you away

@@loturzelrestaurant you are a karen. you are fighting against something nobody cares about. you are pro censoring and one of the reasons why youtube is dying. let people express themselves. live your own life and stop acting like the main character.
The interesting part of the eyewitness account is the detail that just after the rockfall the Lituya Glacier (or at least a part of it), briefly rose to be observable from the bay entrance (normally it is hidden by the mountain slope that took the high water mark) while losing chunks of ice. After it fell down the witness saw the wave breaking against the slope and continuing towards him. It was night, so the witness probably did not see that it was the initial water surge from the splash that lifted the glacier up (also much of the splash saw hidden by the slope that lifted the far more contrasting white glacier just above the slope).
I was looking for an animation showing what the witness saw, but I can't find one. So I am having trouble picturing exactly what he saw.
It is still daylight at that time of the year in Alaska, it's nearly 24 hour sun at that time of the year.
@@danasuperstar look up the mega tsunami documentary from the discovery channel. They have an entire story and show you just what the men saw. They even have interviews from them both.
The sea has been pounding the land with waves for eons.
Here the land sent one back.

The land got revenge!
(But it caused another tsunami, smashing even more land.)
@@loturzelrestaurant what
😂
@@loturzelrestaurant imma start by reporting you
Glacier slide seem to also be a good explanation for the 1936. wave in Lituya Bay (and the regularity of the waves in the whole) since no visible landslide had occured at that event, but glacier is a huge store of potential energy in itself as evidenced by Kolka-Karmadon slide.
Legend has it that these waves are still rolling around on the oceans surface today
Quite literally, the Oceans Ate Alaska.
I never believe in a 500m tsunami, this simulation kinda confirms it
Keep in mind there are witnesses who were actually in a boat near the inlet of the bay and they rode it out and survived. There are old videos out there of them telling their story
Ofc this was a 500m splash not the consecuential wave, but a wave much taller is possible specially from an impactor
If you're in your bathtub and you move from one side to another quickly, the water collects in front on the direction of your body that you move and it splashes up against the tub wall and sloshes over the side creating a puddle on the floor.
This is exactly the sort of thing that happened in Lituya Bay!
I kind of want to watch something like this happen from a safe vantage point. It must have looks impressive but scary.
I almost tempted to die or at least put my life at heavy risk to witness something of this magnitude.
I wonder if geological survey of the zone showed if it was possible for a new landslide to create a similar event 🤔
@@vacciniumaugustifolium1420 Now that's a viral video right there, lol.
The most captivating part would be how relatively slow it moves. Even at the speeds depicted it would probably take ~15s for the wave to peak. One of the eyewitnesses said it took about 4 minutes to reach the ocean.
Me too🙏🏽
@@vacciniumaugustifolium1420 If you knew when was going to happen you could place cameras with satellite internet uplink streaming what they see, before they are washed away. Of course, you'd never know when a landslide would happen.
I feel the Lituya Bay tsunami is a little overrated in terms of historical tsunamis, isn't it? I'm not a tsunami expert but I think that the status of the biggest tsunami ever seems a little bit misleading here since the 0,5 km wave height was caused by hill flanks being very close to the initial splash and water raising to this height not but the actual height of the wave but because of the rise of the water uphill on the flank. It's still pretty incredible and powerful for sure, but when you compare it to Chicxlubux or Fogo tsunami it seems to be a completely different category.
Chicxlubux only triggered about a 100m wave because it landed in the carribean, whose waters were shallow at the time. It didnt land in the pacific where its estimated it'd have kicked up a 4000 m wave. But didnt. Because that isnt where it landed.
@@alexandraleian212 It's hard comprehending a 4km wave. I've stood next to the Burj Khalifa at 880m, 4km wave would be insane.
The definition of megatsunami has only ever been dictated by wave height, generally anything above 100m. Nothing says a megatsunami must have a global impact.
@@callmeshaggy5166 Ok. But I keep reading in news or pop science magazines that this was a wave about 500m tall while it was wave tall ten of meters and 500m it reached because it slided upwards on the opposite hill which is to me completely different thing. Still impressive but it's not just 500m tall massive wave on the open sea. It was apparently a wave of tens of meters sliding over the hillside and there reaching 500m. It's like saying once I was tall 1k because I went hiking to mountains.
@@patmull1 I kind of agree with you tbh
Although the water reach more than 500+ meters but the magnitude or the power of this tsunami is very small and short, typical a landslide tsunami only large at local place.
I am curious if you could run the same simulation but with the glacier slide occuring first and triggering the mountainslide? Would it produce the same wave? One interpretation of the account of William Swanson seems to indicate the glacier rose before the mountainslide.
Probably not since there are other factors that contribute to the wave
But this simulation gives the idea of what happened so it’s cool
With all due respect, there is a mistake in the information this otherwise great video is showing. Indeed, the 524 meters were the runup or “splash over the mountain” of the wave and not the wave itself. However, even the scientific paper you cited on the description says the wave itself was between 100 and 200 meters (not higher than 200). There’s a lot of other studies like the one made by Fritz and cols titled “Lituya Bay Landslide Impact Generated Mega-Tsunami 50th Anniversary” that agree with this (152 m) being the height for the wave.
“Mega-Tsunami” is a term that varies in definitions, but generally is used to designate tsunamis that are several tens or hundreds of meters tall. If the wave itself was between 150 meters and 200 meters tall (which all of the studies we have cited seem to agree with), then the wave fits or gets really close to fit the definition of a mega-tsunami.
The reason most scientific sources and even the BBC use the 524 m runup and not the wave height itself is because these kind of natural events/disasters don’t allow us (for obvious reasons) to make an objective and detailed measure of wave height. So we can only estimate the height with scale models, but there’s no way to have all the factors involved to create that wave applied to a scaled model, so its only an estimate that’s not certified to be true. Nonetheless, we do have the objective measure of the height of the damage the wave does to its surroundings, and no wave in recorded history has ripped all the trees out of the ground to a 524 m height, excepting for this one. So this is, in fact, the biggest wave in recorded history.
While no human-eyes could witness that massive wave (the witnesses were far from the slide and the splash of the giant wave, and they “only” saw 15-30 m waves that had travelled a longer distance from the slide), i can’t help thinking some animals in the forest maybe did (and I don’t think they lived to remember it). Such a magnificent and horrible sight it must have been.
250 meters initial height, 150 meters when it hit the shore.
So basically it wasn't a tsunami, not a huge wave traveling onwards for a long time. But more like a massive splash where tiny parts of the overall water mass reached 500+ meters. It clicks with me now. Before this video it didn't make sense to me that such a small(relative to the size of this whole bay!) rockfall would cause an actual, 'typical', 500 meter tsunami. The area of the rockfall just looks way too small compared to creating a 500 meter WAVE.
What a perfect storm of locality and the slide/glacier/long narrow ford working together!
It is still a mega tsunami. In fact most mega tsunamis are thought to be caused by a "large, sudden displacement of material into a body of water."
thank you! im over here wondering why you wouldnt consider this a tsunami?
Let's take the RMS Titanic and stand it upright. Then get another Titanic and stand upright above the first but cut this one in half. That is how tall the tsunami allegedly was.
Seems incredible
Sorry but that's wrong. This was not the wave height but rather the run up wave height. Depending on the angle of attack of the shore line there can be a substantial difference between the two. I don't believe there is an actual "wave" height I have ever seen make a distinction between the two.
The wave was too much bigger with a height of 525 meters
@@diGritz1 Yes, you are right. It was the runup that was huge. I actually found that out shortly after I got your reply. But I thank you nevertheless for correcting me.
this is wonderful simulator of Lituya bay tsunami 1958.
so which mean, 500m is just few sec when hit that front of Mt.
and the wave is so huge but not a almost 50-100m.
What name of simulqtor
Of course this will be the highest Tsunami because the measuring point was just next to it and the splash is what made it look higher. 523m height was the initial impact and splash. Real measurement of the wave's height should be after a considerable distance of it travelling. Also the narrowness of the bay caused the waves to be higher when the water rushed through
Wait til you find out every tsunami in history was measured by it's highest run-up height where it can still cause damage and not the crest height, which varies wildly depending where in the ocean it's measured.
@@callmeshaggy5166 Yeah people always forget this when they talk about "90 m la palma tidal wave"
@@callmeshaggy5166 not at all, the highest tsunami wave of 2004 tsunami is around 30-34 in northern Sumatra with maximum run-up 51 meters.
Great video. The height of this wave has been misunderstood but other sources clearly. Also if the run up wave height exceeded 500 metres then does that mean the depth of the bay at that point must have been close to 500 metres? I understand that the comet which wiped out the dinosaurs created a tsunami around 100 metres tall. It’s height was capped at that number due to the depth of the water in the Gulf of Mexico being only ~100 metres deep. Is this principal relevant for the Lituya Bay wave? Appreciate any responses.
i think it only reached 500m because it ramped up the side of the mountain. so the wave really wasn't 500m tall, more like water ended up 500m up.
im not sure depth limits tsunami height 1 to 1 like that, but this is pretty unique to most tsunamis because of the "ramping" effect.
Btw the deepest part is about 220m
@@schultz6622 I see. Thank you
"Wave height" can apparently mean 2 different measurements - height of the maximum wave crest above the pre-wave water level, OR the maximum height inundated if the wave were to strike land at the measured point
Honestly I’d rather die in lituya bay watching something incredible like this than die in a hospital bed. It’s a much more entertaining way to go out.
Excellent analysis.
Birds : what a nice day innit?
There is nothing about the definition of megatsunami that dictates it's area of effect nor it's source, only it's height. You have no scientific grounds and are just plain wrong claiming this event as _not_ a megatsunami.
this is what happens when your mom jumps in a pool
The sea was angry that day, my friends.
Like an old man trying to send back soup in a deli.
came for the video, stayed for the music
Imagine just watching it come at you and realizing you just gotta hold on and embrace the gnar 😅
what program do you use
ItsVas no the program he uses to simulate tsunamis and other stuff
You guys should've put a boat in the animation
Luego de ver varios videos con este al fin entendí como sucedieron las cosas¡ excelente explicación 👍
so its literally a splash(mega one) that occurred waves.
Soothing background music though 🙂
2020??
2021?

2020 corona virus tsunami
Great visualization! Thank you!
They could render the two boats in the animation.
Without references, is hard to estimate magnetude.
Just imagine two of the pixels are boats
It always bothered me to see people describe this tsunami by visualizing the empire state building being submerged by a wave.
just imagine if there really was video footage of this event.
goodwork.
i thought the wave was higher than the Empire State Building🤔Who to believe nowadays eh🙄😅🤔Good video, merci☺👯🐶
It caused a 523m peak run-up, which is much higher than the empire state building, but this was just caused by the change from kinetic to potential energy caused by the topography rather than the actual wave being 523m high. As this video says, it is more akin to a "splash" than an indicator of the actual wave height, although the wave was definitely huge.
It was, it was
Hory Sheet! 🌊🗽
Canadian eh
It was bigger 🤦♂️
Impressive but smaller compared to the ice age floods.
4:11 you are making piss off and laughing at same times
"That's not mega tsunami..." Really? Any earthquake will causing big impact, giant stone, glacier anything that fall into bottom of ocean will causing tsunami
Mega tsunami 💀💀
Seems like you don't understand the term of Mega tsunami, there's a huge difference between a normal tsunami and a Mega tsunami
Why does everyone always talked about tsunami height? Did You know that the tsunami 'intensity' is more destructive than the height of tsunami....in 21th century, 2004 tsunami is the most powerful tsunami for now.
If you were waiting for the actual simulation 3:56

WEY SI JAJAJAJAJAJA
No
💯
Nah
From who
Where is the wave of 5km high?
Kesaya Hofland theres no proof of it existance
That was supposedly the one from the Chicxulub impact, but apparently that was a calculation based on the impact being on deep water and pop culture just ran with it. The publication that made that estimate actually says that, since the impact was in shallow water around 100m deep, that was the height of the wave too.
500m
An Intensity XI Earthquake Struck Lituya Bay triggers a landslide and cause tsunami the casualties was only 5.
Can you believe it only killed 2 people
Cvnfess because there was only 4 people 50% of KILL.. maybe if there it was 100000 50000 would die! MAYBE
math 100% lmao@@phill93
It was 5, 2 on a boat and 3 on the island. And it's not really surprising as it's an isolated bay. What was surprising is that several people managed to survive onboard small boats.
Dude this was in the middle of Alaska, of course there was almost no one there
There were only 5 people there idiot
why big?because it happened on bay
It's sad you missed a couple of seconds of 4'33"
I find it kinda similar to the El Reno tornado in terms of how it’s viewed
Theres a mointain pass in california called the altimont thats a 1000 feet you can see it for miles but this is horifing
What does a mountain range have to do with this
@@DasaniSaltWater The fact that those mountain are huge but this tsunami was Even more taller
So it wasn't even a tsunami...
Guys
If you go to Google maps with no setalite cenotaph does not exist turn on seatelite and you see cenotaph island
the world's biggest tsunami was thousands of meters high from an asteroid
MoreCubby nope. It was this one.
There is no proof of that tsunami wich makes this the highest Ever we humans can confirm
duthegamer Are you going to play COD WW2?
MoreCubby mhm it was the asteroid that killed the dinosaurs that caused that tsunami
Nope. That asteroid landed in waters only 100m deep.

After the "splash" the tsunami waves were like normal tsunami waves
PotatoChips23415 That doesn’t make any sense just because the waves after the splash were normal waves. It still reached a maximum height of over 1,700 feet. The following waves aren’t always larger.
It was and it was taller than the Empire State Building ok
I like it ❤️❤️❤️❤️❤️
Megasplash, not a megatsunami
Pingu no it was a tsunami
it is a mega splash but cause a 500m tsunami so its called mega tsunami
I will sail here to see it in my 24' gladiator
How high it would be just watching World highest statue of unity makes us wonder , what if this type of tsunami comes in a high population area like china India
523m its splash! but not mega tsunami
Who's here from Daily Dose of Internet ?
Here yo
The place is too small to become a world's largest tsunami
Nobody should be saying it's the largest. Just the highest.
Good thing that no one lives on that area
i read at google that this tsunami "miraculously, only killed five people". yeah lucky for you it didn't happen in LA or SF

No, I was curious searched what was the biggest tsunami

All I have to say is hell no!
I think you mean "fjord."
Nice catch. Still a great simulation video though
İts also in bolgen movie
Fjord!! With a J!!
Who knows what happened that night .
That’s almost as tall as the one World Trade Center?
taller
Isn't it fjord jot fiord
So it's just a megasplash.
That produced small tsunami waves that wrecked boats. Those waves have estimates from 20 feet to a hundred.
Im here bcoz of tiktok
It was a mega tsunami ...
Wawawewa.
Tik Tok me trajo aquí xD
dajcie pl napisy

From red tide
oh
The wave was created by an earthcuake not by a rock fall
awesome event yes, possible and i say possible water pushed to that height but not a wave, and a splash is nothing or even in the same category, so if it was a splash then its not a tsunami therefore isnt the biggest, 2004 tsunami now your talking one of the biggest recorded
