Even the rear side of Santiago island facing away from Fogo had large runups. A 500m runup is like Lituya Bay but across 60 km of open ocean, that's a tremendous amount of energy.
Imagine being on the top of Santiago enjoying the view of Fogo in the distance When suddenly the entire fucking mountainside gives way and a 600m tall wall of water is barreling towards you
I like your final point “mega tsunami happen”. I know a particular group of scientists who need to come to terms with that. Specifically regarding the canary islands. But they won’t of course. Because disaster preparedness is expensive.
The same thing happened in the Hawaiian Islands where seashells were deposited on the tops of other islands after the Big Island cliffs fell. Look at the terrain near Waipio Valley, Big Island and you will see the evidence of the hillsides that suddenly dropped and caused a major tsunami.
It’s funny, I’m here in Tarrafal, which sits across from the volcano I’m from the volcano which is called a Chan the volcano last irrupt it in 2014, but I believe it’s on the way to irrupt anytime soon the magnum chamber has shifted. It is no longer underneath the volcano. The next eruption is going to happen underneath the old crater the old cold Calderia
Gotta remember folks, runup is always bigger than the actual wave. Like that other rockslide in that other bay in Alaska, the wave itself was only around 100 feet tall, but the momentum and energy behind it carried the water up 1700 feet that side of that mountain. Same applies here, the wave may have only been about 100-300 feet tall. Good example is making waves in your tub, waves are small but when it splashes against the side it spits up many times the height of the wave.
This is basically like taking one of the largest Rocky Mountains like Mt. Yale and dropping it directly in the deep ocean, cataclysmic levels of energy.
"Paleo-seal level". I was going to point out the difference in sea levels approx 70, YBP. :) Mass, falling from a greater height, may have had a more dramatic effect.
Crap, really? Damn, and I thought as a New Yorker I had to worry about the impending collapse of the La Palma island in the Canary Islands, which would produce a mega-tsunami that could hit the whole of the East Coast. Now I have to worry about Fogo island too? The scariest part of this is that it happened around 75,000 years ago, meaning that this happened around 60,000 years before there were even humans in North America. This is why the Native Americans of the East Coast have no myths or similar historical recollections of 50 meter tsunamis hitting the East Coast...
You have nothing to worry about. Do you really go to bed at night in fear of La Palma collapsing??? Might as well move to Manitoba, close to geographical center of North America, I guess that's far enough away from the oceans to keep you "safe"...
How comparable are tsunami waves? The 40.5 m tsunami in 2011 Japan was 2.4 m when it hit the US west coast. Could we extrapolate from that and estimate that a 300 m wave would be around 18 m when it hit the US east coast, or maybe a bit larger since the Atlantic isn't as wide as the Pacific? That would be a nasty wave indeed, hitting the American beach communities and eastern cities right at sea level.
RE: "could we extrapolate..." James, For tsunami, there are a few factors that vary case to case (e.g., physical dimension of the source, direction of wave radiation patterns, depth of water at source, non-linear behaviors), but as a first guess there is nothing wrong with extrapolating tsunami events that we have seen to tsunami events that we have yet to see.
These are great and all, but damned man. You need to have either some commentary, or some music. Maybe something like Wipe out, or something. Great animation though.
jhiv3945 man! what a connection! i NEVER saw your comment before i entered mine. Word for word,eh? amazing. but i must say i 100% agree with your post...
Dear ingomar200, Would it be too much to ask for in depth looks of tsunamis in areas (that you haven't covered yet)? I'd be interested in areas like Sydney, Major EU metro areas, the area from Rio to Buenos Aires, even closer looks at cities like New Orleans or Miami. Even the West Indies are subject to a closer look. If you can't because you are too busy, I'll understand.
Steven, magma uplift has been raising the elevation of mountains, islands and continents for hundreds of years - probably longer. You might want to pause to consider that the island has been lifted up in elevation - as much as 1,000 feet -over the past 50 years, which is documented in other locations of the world. Across a span of hundreds of years, the uplift could have been considerably more.
Just watching the scar on fogo and the volcan inside now, I can't help think that is just what happen also on Tenerife (Canary Islands), Las Cañadas its identical with the Teide inside. What about a simulation about the part of the island fall to the sea and created the caldera? And El Hierro? For sure those two also created mega tsunamis.
Very, very, very, very, low....Probably no wave at all. The splash would spread out and quickly fade away. A rockfall like that would create a big surge on the neighboring islands, but farther out, it would quickly fade to nothing. What YOU want to do is to learn more fundamental physics.
@@Scottish-Greg it would if mega tsunami did occur... it will have world wide impact... and if the volcano erupted even more violently then definitely will have world wide impact...
Like ocean touching the sky i guess... if this type of scenario does happen i guess for earth its normal but for us it would be like witnessing something out of this world... like that movie interstellar
I wonder if one of these land slide tsunamis have ever set off a chain reaction of a bunch of volcanic islands all having land slide events and setting off more tsunamis...
The tsunami inundated far up Santiago with 400-500 meter runups. Before when the tsunami was first generated from the landslide, it said the tsunami was 600 meters high!

Imagine if Fogo had caused this mega tsunami during Nov 23-25, 2014 when it rumbled to life. I remember reading a pdf about that volcano's tsunami potential, the year after. The things you never know...
It'll be really sad because I know a person who lives there and it seems the wave will hit Guinea-Bissau too...I can't imagine it. Hopefully my woman's country, Angola, doesn't be affected. I think the government of those countries should really do something to reduce the amount of land from the volcano in order to not let it fell down so hard, that way the wave will be shorter than the expected. Is it possible? If so, what are you scientsts waiting for?
Why most interesting things happen not in our lifetime. Would be good to witness giant tsunami approaches or asteroid impact somewhere near. Deadly yes, but insanely beautiful.

Very interesting! Must've been quite a terrifying sight on Santiago. Over 200,000 people live on that island now, it that happened today, it'd be quite the catastrophe. One question, how are mega tsunami waves able to cross whole oceans? I've been on the side that trans-oceanic mega tsunami are possible, but I've heard the opposing point of view that says only local megatsunami are possible, that the wave would dissipate before it reached a distant shoreline. Why do people hold this view? Where are they mistaken? I'm not saying you're wrong or anything, I could kind of understand that point for La Palma, as it is such a small island in comparison to something like the Big Island. The volume of the La Palma collapse was 500 cubic kilometers and this collapse was 200 cubic kilometers. The Hilina Slump is at least 100 times larger at 20,000 cubic kilometers. A collapse like that would almost certainty generate a devastating mega tsunami that would hit the West Coast of the Americas, but only because the amount of rock falling into the water is on another order of magnitude. La Palma and Fogo would certainly have devastating effects locally, I'm unsure whether or not their megatsunamis would be trans-oceanic. Only the monster slides that have occurred off the Hawaiian chain may have been large enough to create trans-oceanic megatsunami.
+tornadolover Hello tornadolover. Why do people hold this view? This is a good question. We have 100s of examples of earthquake tsunami crossing the entire ocean with little dissipation. I don't see why waves 10 or 30 times larger would not do the same. Those that call for vanishing waves will have to come up with some physical reason why mega tsunami are different from other tsunami. A big issue is that mega tsunami are infrequent, somewhere on Earth one happens about every 10,000 years. With sea level going up and down all the time, there is little direct geological evidence of distant wave propagation to make the case either way, so many conclusions are drawn from numerical models and these are not as cut and dry as you might think. You can increase model friction for example and the waves will just go away. Someday an indisputable fingerprint of distant mega tsunami will turn up and this question will be answered. Did you read recently about the observation of the Storegga Mega Tsunami (8ka) being found several 1000 km away? That tsunami certainly did not vanish.

ingomar200 They argued that the shorter wavelength of a megatsunami would be a critical factor. However, the wavelength would increase as it radiates outwards.Also, they stated that regular tsunami has a much more "spread out source", an earthquake fault line. But the evidence you presented seems to point to the contrary. What's interesting is that the Hilina Slump is four times the volume of the slide you mentioned there. If that slump collapses catastrophically, it will generate a unimaginable megatsunami.

ingomar200 Dr. Steve Ward, Yes, but it'd be a pretty bad day for America. I recall your previous simulation where you had a partial collapse of the slump , just 900 cubic kilometers of it. I imagine a full collapse would produce a more destructive wave. I just pray that if it does happen, a tsunami warning will still be issued. I hope they're not like "Oh, only Hawaii will be affected by this, the wave will fizzle out." That would be fairly criminal, because, based on your models, it's almost certain that California would face an Indian Ocean like tsunami in such an event. I appreciate you showing me this interesting information and communicating with me about this topic!

The collapse is spot on but the "wave" seems completely wrong as the "water"(seawater) is "displaced" not "pushed" thus the "wave" would start from the opposing land first ("for ever action there is an equal and opposite reaction") thus technically "drawing in"(and massive up) a "liquid mountain" on account of "that other land." In this instance that would not very easy to have happen because the coastline is so deep along the opposing island anyways meaning the water is simply too massive to be drawn towards the displaced mass thus causing a massive wave *AWAY* from said collapse. If anything i would think the exact opposite would happen here as the "slide" causes a massive displacement which then draws the water away from the opposing Island and right back towards where the Volcano shield gave way "tensile strength of water." If this were a "strato-volcano" that collapsed in upon itself ("the entire Island explodes") that would be different of course. (Present day Krakatoa.) There aren't too many examples of actual visible Strato-volcanos that are active although I did see one erupt in Alaska with shield Volcanos far more common. Olympus Mons on the Planet Mars is a spectacular example of a Strato-volcano...the largest in our Solar System that I am aware of.
Now imagine the cosmic impact that created the Burckle Crater in the Indian Ocean and the tsunamis it would have generated- the remains of the event are a crater 18 miles wide on the seabed under 2+ miles of ocean depth and 600’ tall chevron shaped deposits on land in a circumference around the impact site on several continents.

Yes, but it'd be a pretty bad day for America. I recall your previous simulation where you had a partial collapse of the slump , just 900 cubic kilometers of it. I imagine a full collapse would produce a more destructive wave.
I just pray that if it does happen, a tsunami warning will still be issued. I hope they're not like "Oh, only Hawaii will be affected by this, the wave will fizzle out." That would be fairly criminal, because, based on your models, it's almost certain that California would face an Indian Ocean like tsunami in such an event.
I appreciate you showing me this interesting information and communicating with me about this topic!
Eu sou Caboverdiano! No mundo em que vivemos, tudo e possivel! Nao so por Cientista, tambem por disobidencia a Deus! Esta na Biblia que Deus da o homem a inteligencia, Ekes esqueceu donde veio a inteligencia! E se acabam, com a sua propria intiligencia! O que o homem inventa, so estao acabando um com o outro, e esquesa do mandamento do Sr.
The collapse is spot on but the "wave" seems completely wrong as the "water"(seawater) is "displaced" not "pushed" thus the "wave" would start from the opposing land first ("for ever action there is an equal and opposite reaction") thus technically "drawing in"(and massive up) a "liquid mountain" on account of "that other land."
In this instance that would not very easy to have happen because the coastline is so deep along the opposing island anyways meaning the water is simply too massive to be drawn towards the displaced mass thus causing a massive wave *AWAY* from said collapse.
If anything i would think the exact opposite would happen here as the "slide" causes a massive displacement which then draws the water away from the opposing Island and right back towards where the Volcano shield gave way "tensile strength of water."
If this were a "strato-volcano" that collapsed in upon itself ("the entire Island explodes") that would be different of course. (Present day Krakatoa.)
There aren't too many examples of actual visible Strato-volcanos that are active although I did see one erupt in Alaska with shield Volcanos far more common.
Olympus Mons on the Planet Mars is a spectacular example of a Strato-volcano...the largest in our Solar System that I am aware of.
It’s happening as we speak, La Palma
There was a tusami in were I live am in one building 7th lucky I have wi-fi
you think Tusami is bad. My village was once hit by a salami!
MrSolider How about you go fuck yourself and not tell people to kill themselves for no known reason
uff
MrSoldier no u
Dante Salgado You know what? Stop telling people to kill themselves just because of something they like.
So all the GBT will gonna Destroy?
In La Palma?
amazing
And its happen in Krakatoa Island that makes tsunami on Anyer Bay 22 Dec 2018
You have some good music in videos(this a joke don't you little kids take me serious
so freaking cool
“Dakar, Africa”
like
“Washington DC, North America”
It's in Senegal, right?
In what modeling criteria were they based? from what I see in the video, I think you are assuming circumstances that may not be real.
It happened a long time ago, so yes, we may not know If It happened, but there is litterally a scar in the island
Definitely needs some music of a narrator.
You know.. some audio can make a video more enjoyable..
Good vid, but the plural of "tsunami" is "tsunamis," not "tsunami [sic]".
Now imagine the cosmic impact that created the Burckle Crater in the Indian Ocean and the tsunamis it would have generated- the remains of the event are a crater 18 miles wide on the seabed under 2+ miles of ocean depth and 600’ tall chevron shaped deposits on land in a circumference around the impact site on several continents. This happened only 5000 years ago.🤯🤯
Hello every flood myth ever from nearly every ancient culture around the world.
Welcome to the consciousness of regular cosmic destruction on our planet, folks.🤷♂️
ESTÁ SEM ÁUDIO,POXA UMA MATÉRIA ÓTIMA.
Maybe a 👌bit if sound perhaps…. Maybe some Bach, Glenn or Diddy …..
Get recomended
Americans worying about Northern African tsunamis me living in Portugal shore much closer to La Palma and Fogo...hahah
Мега цунами, - это минимум) километр
А то, что показывал, так - волна небольшая😄
When this tsunami hits even more far away
Soy palmero 🇮🇨
Oh man what song you use?
It sounds so fuckin awesome
@@raromo The joke flew over your head you moron. Big r/woooosh right there.
As this video has no sound, try watching it whilst listening to Dies Irae from Mozart's Requiem.
i'm from cabo verde Maio and Maio is flat and the sea is not too deep so i don't think this would do this damage !
There is a theory that the Richat Structure in Mauritania could be Atlantis. looking at google earth you can see what looks like markings left by a flood around that area on the west coast of Africa.
is it possbile that a wave caused by this volcano could make it that far? the vast majority of the area on the coast of Mauritania is
No sound?
