He left out, all that rock fell around 3000ft off the side of a mountain and then hit the water...wasn't just a landslide

[Soundtracks]

This is the biggest known tsunami in Earth’s history. I can’t even fathom how horrifying it must’ve been for the people who were there to look way up and see nothing but a colossal wall of water coming towards them while still being pretty far away from it. Truly something out of a nightmare

[CarsenBitz]

As an Alaskan, seeing the aftermath and effect of this massive wave (even still today) is crazy and the devastation it caused to the land is unparalleled. As a reminder, don’t take anything for granted because u don’t know when a life threatening event might happen to u.

You may find this of interest.

It was actually closer to a
100 ft (30 m) wave which caused destruction as high as 1, 720 ft (520 m) above the surface of the far end of the Bay as its momentum carried it upslope.

This is called run-up.

The wave caused damage to
the vegetation up the headlands and up to a height of 524 meters on the far end.

It also created a damage line up to 213 m (699 ft) around the outline of the bay, with evidence of this damage line still visible from space to this day.

Lituya Bay is a tidal inlet with a maximum depth of 722 feet (220 m).

It is MUCH shallower in most places.

This amount of water will not generate a wave that is 1, 720 feet but again,
due to its shape the
run-up is capable of “sloshing” that far up the hillside.

As the water rolled back into the sea there was tremendous surging action taking place for some time afterwards with much logs and debris in those waters.

The narrow entrance of the Bay has a depth of only 33 feet (10 m).

The Ulrich’s boat,
the Edrie, did not end up on the shore-
the wave passed under them as it was a surge and not a breaker-
they then rode out the smaller ensuing waves and eventually exited the inlet.

“The wave did not go up
1, 800 feet,
the water splashed there.”
-Howard G. Ulrich,
Captain of the Edrie
as quoted from
"Giant Waves in Lituya Bay, Alaska".
Miller, Don J. (1960). Geological Survey
Professional Papers.

Basically,
they were in a place where the wave passed under them as a giant swell-
a breaking wave would have taken them and then rolled&crushed them.

Like the Wagners on the Sunbeam,
that was destroyed with no survivors.

I know that this is not as astounding
as the misunderstood, sensationalized versions that many people favour but…
these are the facts.

That bay is simply nowhere deep enough to produce a wave that big.

It was like water sloshing in a giant bathtub…
if the giant suddenly stepped in
and sat down.

So to speak,
of course.

People need to understand the difference between wave height and run up. The wave in Lituya bay was about 100 feet as it physically moved through the bay. At the head of the bay where the landslide hit the water a splash of water went up the oposite hill side to a height of 1720 feet. Never the less the actual wave that the landslide created was about 100 feet (maybe 150 feet at its point of origin.

How do you manage to beat that wave in a tiny fishing boat?? 😂😂

[kenndogg]

I wonder if the survivors are still living?

[zeyrise]

Imagine casually surviving a tsunami by outrunning it. Damn! What I'd give to be a fisherman.

[lightfruit_l]

I..













































was there…

[seattleblaze]

Only a few sources agree with the 1700ft estimate, most say around 1000ft, but 1700 sounds better doesn't it. Selective BS!

[TylerWSP]

If anyone makes a camera man joke I swear..

[doors]

For reference the Empire State Building is 1425 feet

[aswin]

Informative. But what does Cologne have to do anything with the tsunami in Alaska?? (The city shown in the footage)

[nik]

It was in 1946 and it was 1712 feet or 520 meters

[nornenlowery]

Oh my goodness, first I've heard of this 😢😢

[thedailyhummm]

I couldn’t imagine riding a wave 1700 feet in the air. That must’ve been scary

[DatsiKxModz]

Imagine riding that wave as those fisher men😂😮

La Palma island in the Atlantic off the coast of Africa. The steep hillside on the western side of the volcanic island has signs that one day it may slide into the sea and send a massive tsunami to the UK, Caribbean, and the American coasts

Big respect for the person who measured the tsunami with a 30 cm ruler! 👏🙌

[gerardlang]

The problem is we dont respect nature enough to realize its power and awe. Both devastating and beautiful
