Lituya Bay Tsunami.mov 

Hard to believe one father and son in a boat actually rode one of those out and survived. Seems impossible.

So a Megasplash.

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

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

The sea has been pounding the land with waves for eons. Here the land sent one back.

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).

Quite literally, the Oceans Ate Alaska.

Legend has it that these waves are still rolling around on the oceans surface today

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.

I kind of want to watch something like this happen from a safe vantage point. It must have looks impressive but scary.

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!

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.

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."

I never believe in a 500m tsunami, this simulation kinda confirms it

Excellent analysis.

What a perfect storm of locality and the slide/glacier/long narrow ford working together!

Great visualization! Thank you!

Birds : what a nice day innit?

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.

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.

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.

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.

Luego de ver varios videos con este al fin entendí como sucedieron las cosas¡ excelente explicación 👍

You guys should've put a boat in the animation

this is what happens when your mom jumps in a pool

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.

goodwork.

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.

Soothing background music though 🙂

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

It always bothered me to see people describe this tsunami by visualizing the empire state building being submerged by a wave.

The sea was angry that day, my friends. Like an old man trying to send back soup in a deli.

very clear👍

What name of simulqtor

If you were waiting for the actual simulation 3:56

came for the video, stayed for the music

so its literally a splash(mega one) that occurred waves.

An Intensity XI Earthquake Struck Lituya Bay triggers a landslide and cause tsunami the casualties was only 5.

just imagine if there really was video footage of this event.

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.

Imagine just watching it come at you and realizing you just gotta hold on and embrace the gnar 😅

what program do you use

They could render the two boats in the animation. Without references, is hard to estimate magnetude.

2020??

I like the PSX graphics

OMG 523 M?

I find it kinda similar to the El Reno tornado in terms of how it’s viewed

Impressive but smaller compared to the ice age floods.

Tiktok brought me here

So it wasn't even a tsunami...

Can you believe it only killed 2 people

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.

I will sail here to see it in my 24' gladiator

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.

Good thing that no one lives on that area

All I have to say is hell no!

It's sad you missed a couple of seconds of 4'33"

I like it ❤️❤️❤️❤️❤️

i thought the wave was higher than the Empire State Building🤔Who to believe nowadays eh🙄😅🤔Good video, merci☺👯🐶

Guys If you go to Google maps with no setalite cenotaph does not exist turn on seatelite and you see cenotaph island

why big?because it happened on bay

It was a mega tsunami ...

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

From red tide

İts also in bolgen movie

Do black sea 1901

oh

Humans : throws a rock Ant : Nature : *throws a rock* Humans : *full of issues*

Who knows what happened that night .

Theres a mointain pass in california called the altimont thats a 1000 feet you can see it for miles but this is horifing

Does anybody know more about the theoretical mega tsunami

Fjord!! With a J!!

Fjorde*

onda onda olha a onda

the world's biggest tsunami was thousands of meters high from an asteroid

POV: you came here after watching that tik tok

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

That’s almost as tall as the one World Trade Center?

The place is too small to become a world's largest tsunami

So it's just a megasplash.

Megasplash, not a megatsunami

i read at google that this tsunami "miraculously, only killed five people". yeah lucky for you it didn't happen in LA or SF

I think you mean "fjord."

dajcie pl napisy

Who's here from Daily Dose of Internet ?

Where is the wave of 5km high?

Wait so why isn’t it a Mega Tsunami?

523m its splash! but not mega tsunami

So not a place to spend your family vacation

👏🏾👏🏾👏🏾

Tik Tok me trajo aquí xD

Im here bcoz of tiktok

The wave was created by an earthcuake not by a rock fall

I came here bcs of tiktok video

Isn't it fjord jot fiord

This is cap

B

Mbs brought me here

Guyss SHOWERRRRRRR
