Most beautiful State I've ever had the privilege to visit 4 times, almost stayed & would absolutely love to return!! There's no beauty that matches the beauty of Alaska!!
This isn't the first slide generated Alaskan tsunami generated in the last 100 years. There was another, in Lituya Bay Alaska in 1958. That one was witnessed by two unfortunate men who were fishing in the bay, near its mouth, when the earthquake, rockslide, and glacier sudden uplift dumped 100 million tons of ice, rock and sediments into the head of the bay in only a few moments. Since the early 19th century, there have been at least three such events observed in that bay. That one scoured the sides of the bay to a height of over 500 meters.
It was no boondoogle. I can't think of many more practical studies to the future of mankind. Large tsunamis can result in massive death tolls, and completely alter the Earth. Studying that phenomenon is very wise.
@@Justicia007 So practically, how would a study like this assist the public-at-large? I'm a huge supporter of the sciences and like to know that experts go out to remote areas to discover "stuff", but what is the direct benefit?
A well explained scientific evaluation! The visuals are on point. We can all be scientists when invited in. Thank you for an interesting and thought provoking video.
1000 awesome points for the pyramid metric visual!! This is something that can actually work for people to get some kind of an idea of these huge numbers! Well done, whoever came up with this...give them a raise now, cuz they'z a genius!
Yea they showed the real pyramids and I was like damn ok, I can see how that can displace a lot of water. Then their pyramid started forming and it all made more sense
600 foot wave? That's puny compared to the estimated 1720 foot wave that occurred at Lituya Bay, Alaska on July 8, 1958. It was also caused by a massive landslide from a 7.8 Earthquake. The rockslide was at the closed end of the bay. Miraculously a father and son on their boat survived it.
Glad this was mentioned; don't need to repeat it... Thanks! Simply unreal. Trees snapped off their roots over 1,500 feet above the water line! Yikes!!! Susan Casey's "The Wave" details this amazing event. Still my favorite book and I highly recommend it.
There were 6 people who witnessed it in three boats. Two couples running their own fishing boats and a man and his son running theirs. One of the couples was killed after escaping the inlet but was crushed when the wave crested and fell upon them. The other couple and the man and his son survived. Also the initial run up on the opposing bank was close to 1700' however the wave that carried the boats at least 80' higher than the trees below ( as the man with his son reported) was probably only 150-200' at that point depending on the height of the trees.
@@dudeonbike800 A few years ag there was a movie made about a Norwegian Fjord tsunami called "The Wave" and a sequel "The Quake" that are both very good.
Thanks for the video AlaskaNPS. I live in Juneau and so this hits a bit close to home. There are landslides almost every year around Juneau but fortunately most of them are small and high up in the mountains. I own a sailboat and am out on it nearly every weekend during boating season and I rarely go a season where I don't see the evidence of a landslide somewhere. As for the Taan Fjord slide, I'm wondering if glacial rebound might have also been a cause.
Tsunamis are so fascinating. Before videos of actual tsunamis became widely available, it was hard to imagine how big these waves could possibly be. 2011Japan certainly changed that. Even looking at those videos it makes you question your vision because the landscape changes so rapidly.
Robin this was the largest ever recorded surge wave, not a tsunami. One if not the largest widespread tsunami happened also here in Alaska, you can still travel by boat into prince William sound where the 1964 quakes epicenter was located and see the dead tree line on how high the tsunami went up the shoreline, by the way people who heard about the tsunami were killed a couple of thousands of miles away in Oregon, crescent city California and Hawaii! Look it up!
The Boxing Day tsunamis changed it first really. But huge waves have existed since water did on this planet. Rogue waves are common and not so rogue as they thought, they now know. I’m not sure how rare these giant ones are, but they seem rare and remote enough to never be caught on camera.
@@agentx7138 I’d guess a surge wave is pushed forward by a landslide, a tsunami is multi directional if an earthquake causes it by the tectonic plates pushing upwards under the sea? But that’s a pure guess.
These scientists and educators are to be commented for their efforts! Landslide generated waves are inevitable....better to understand the dynamics now and prepare to save lives!! That’s the whole point of the exercise.
The only way this is going to save lives is if it leads to people being forbidden to build and live anywhere near the ocean shore. Not going to happen, so people will die.
Really interesting and much more so by the fact that they got right there quickly. Sometime the documentaries about something that happened a couple hundred years ago are a little dry. Also interesting that an event the originated on land would be classified as a Tsunami. I always thought that technically, a Tsunami originated offshore and came onshore as opposed to the reverse such as this.
The definition of a tsunami is actually a little vague in some cases. Generally we'd call waves generated by some sudden push of the water a tsunami, except calving waves are typically excluded. Additionally it's now pretty widely accepted to cause waves that are similar to tsunamis that are generated by atmospheric pressure variation "meteotsunamis", but on the other hand when long-period shaking from an earthquake generates harmonic waves in a closed basin it's called a "seiche" rather than a tsunami. It also gets confusing when a tsunami is generated in a lake then spills down a valley and becomes a flood - where does it stop being a tsunami and start being a flood? Finally, the term "displacement wave" is sometimes considered synonymous with a tsunami, however this term isn't necessarily very good either - displacement implies that a volume of material added to the water creates the initial disturbance that then propagates as a wave, but in fact in cases like Taan and Lituya this isn't simple displacement - there's direct transfer of momentum from the landslide to the water. Making it worse, we refer to the whole water event as a tsunami, even though some of it is a splash rather than a wave. So a tsunami may or may not be caused by an impulse, which may or may not displace water, and may or may not be a wave.
To see how much land it moved.. I find it difficult to believe Grand Canyon was carved out by the current river there.. - I believe a huge body of water was involved
The Grand Canyon was at one time completely full of water. It is only a small stream of what it was at its greatest. It would truly have been a sight to see.
I recommend researching lichtenberg wood burning and the effects that electricity creates... i think this is a better explanation for large canyons instead of river carving...
@@-Awareness yes indeed a mega lightning bolt. a mico nova or amassive CME from the sun would make this and maybe most large rivers and canyons . it sounds plosable
The motto, "Everything is bigger in Texas" should be reappropriated to Alaska. In many of these shots, it's difficult to get a sense of scale. Those shots that do contain a sense of scale provides an indication to me that everything seems bigger in Alaska. *_TRUST !!_*
@@josephastier7421 sometimes, a tsunami is not always about the height but it's about the energy wave, a tsunami caused by a landslide usually it's just happen in the close area to the source, unless if the landslide is very large but with megathrust earthquake the ocean floor can be lifted along the tectonic rupture for thousand kilometers at once just like the indian ocean tsunami 2004, the indian ocean tsunami 2004 produced more energy than this tsunami althought this tsunami was more tall, a megathrust earthquake can cause a teletsunami or a tsunami that spread all over the ocean and can devastating the coastline far away from the source, that's why the indian ocean tsunami can reach East Africa, Somalia 5000 km away from the source( Sumatera )and killed hundreds of people there with 10 meter tsunami. A 10 meter tsunami caused by a megathrust earthquake is enough to destroy a town. The indian ocean tsunami 2004 by far is the most powerful tsunami in 21th century.
A tsunami is water, I think. A landslide caused this event, I think ? The water went out the fjord toward the ocean, I think.....at what point did the water, come back as a tsunami and run up shoreline pulling trees roots and rocks etc down. Obviously I missed a lot here. Why is this event not called a gigantic landslide, that triggered a huge wave ? I am not being cynical, as some comments seem to be.
Nope. A huge slide of rock and ice dumped into the head of this bay in a matter of seconds. All that rock and ice displaced the water it encountered away from the impact of the slide and sent it back down the bay in the form of a 300 foot wave that, in true tsunami fashion, pushed a huge torrent of water as much as to 600 feet up the near vertical slopes of the bay on both sides. Two hundred million tons of rock and ice moved 200 million tons of water from full stop to 500kmh in a few seconds, and that water was pushed miles down the fjord as a result. Tsunamis are not like wind produced ocean waves, where there is little lateral movement of the underlaying water. Tsunamis move blocks of water almost instantaneously and they propagate for sometimes thousands of miles before they reach equilibrium with the surrounding water body.
@@boydgrandy5769 So, it was a huge land slide, that moved itself and water down the fjord, and some came back. Scientific terminology omitted in order to confuse the laymen 😁. Thanks 👍🏻
Lituya bay surge wave was the largest recorded in the world! It happened in 1958, it has happened in the same Alaskan bay before, ask scientists, I have flown right over it by floatplane, you can still see how the “”surge wave, not tsunami “, went about 1700 ft up the mountainside!
Everybody needs to watch the 2004 tsunami documentary. Then watch the movie The Impossible. One is a documentary of survivors from 2004 Indian Ocean tsunami. 230,000 + people died. The Impossible movie portrayed the actual event very well. Thank me later
600 foot high wave? Bullshit. That might be the distance up the sloped valley wall the wave traveled, but that wasn't the HEIGHT of the wave itself on the open water.
Dirt Flyer - The written description for the video says 600 feet. And in reality, the wave was likely well under 100 feet and probably closer to 60 feet, not 300 feet. Second in tsunamis, the height is not that high. It's the long wavelength from the displaced water and that water volume behind the wave peak that causes the run-up distance, not the height of the wave itself.
@@puma.will.pounce7590 I'm no expert on tsunami wave heights, and I won't pretend to be. I do know that mega tsunamis formed from enormous landslides are a much different animal than tsunamis from subduction zone earthquakes. I also know that a 600 foot wave gets many more clicks than a 60 foot wave, so there's that.
I surfed that wave.i just finished my coffee and chocolate cake when I heard it,lucky for me a log was in the wave so I casually stepped on it and rode it,but,I hit another log and landed on that big mountain! I suppose that's good luck.
Pretty easy to look up based on the info provided Approximately 40K. Includes boat time and travel for several researchers. Not sure if anyone took salary but if so, it was minimal. www.nsf.gov/awardsearch/showAward?AWD_ID=1650357
Without photographic evidence of a 600 foot high "wave" having been generated, I would doubt that any such thing actually happened. If it had happened, it would have resulted in some evidence beyond this particular fjord. I have seen other fairly large landslides from above water courses and it is true that when the rock displaces the water initially, there is an enormous "bulge" at the surface of the water that slops back and forth for a several cycles and the water can slop up the slope for a good distance tearing out trees and loose earth but it does not manifest itself as a typical wave with a crest like the one illustrated in this video. It would be devastating to be present at any low level when the rock entered the water and when the backwash occurred. You could not survive it unless you were safely above its limit, but a crested wave that no one noticed? I don't think so. A wave that large, if it had resulted from the rock slide would have found exit at the mouth of the fjord and would have immediately lowered to a wave a few feet high until it got to open water after which it would have reduced itself to a foot or less and might not have raised an eyebrow when it got to Japan. I suppose it doesn't bode well for the next expedition if you don't maximize the size of the event that you're investigating on such scientific jaunts.
These tsunamis don’t last very long though do they, I believe due to their wave form and the geography? But it would be damn impressive to see one captured on video. I remember the story if two American fisherman in a place like this and the same thing happened, and they actually rode over a massive tsunami. Shame they didn’t have video phones haha. They survived fine to tell the tale, can’t remember where they were though when it happened.
That's because the water was only 90 meters deep. Though a landslide like La Palma collapsing into the sea will be devastating, it'll travel from Africa all the way to the Americas.
Joe, you obviously have no clue of this area of Alaska and how massive this was, just didn’t get any coverage because it was in Alaska in a pure, remote non populated wilderness area here in Alaska! Your clueless! This was a massive mountain landslide that dumped huge amounts of debris into a narrow fjord and produced a huge surge wave that pushed through the bay, you as most are clueless about things that happen daily in Alaska, most can’t comprehend!!!
rockn roll , satellite photo. Why you have such a hard time understanding Alaska? Want one better? You tube lituya bay Alaska mega wave! Largest “surge wave”, ever recorded on earth, 1958, caused by a massive earthquake, trigged tons of rock and debris down a steep mountainside into the bay, pushed a wave across the bay and went up the mountain 1300 ft!!! Look it up, watch the vid, two survivors an Alaskan native and his son! To this day you can fly over it and see the scar line of how far up the wave went! Check out the vid!
Too bad there's not something like a Vortex Cannon or sound Cannon floating out in the water facing towards the shoreline and facing away from the shoreline so that in an event of the earthquake or something they could be set off to counter uncommon approaching waves. Anyways of Their Own

Wow. They get paid to see how this dirt/ ground moved n why it caused this wave. Let’s take a look at satellite images n see where the large amount of dirt came from.

Music is louder than the speaking, cant hear what they are saying!!!!!
Most interesting. Next presentation, perhaps you could leave out that annoying and distracting background elevator music, PLEASE!
Researchers are weird bunnies. I wonder how much money this all cost.
@William Daniels I know right?
Pretty easy to look up based on the info provided Approximately 40K. Includes boat time and travel for several researchers. Not sure if anyone took salary but if so, it was minimal. www.nsf.gov/awardsearch/showAward?AWD_ID=1650357
Tem como acontecer tsunami no Brasil e em que áreas
Without photographic evidence of a 600 foot high "wave" having been generated, I would doubt that any such thing actually happened. If it had happened, it would have resulted in some evidence beyond this particular fjord. I have seen other fairly large landslides from above water courses and it is true that when the rock displaces the water initially, there is an enormous "bulge" at the surface of the water that slops back and forth for a several cycles and the water can slop up the slope for a good distance tearing out trees and loose earth but it does not manifest itself as a typical wave with a crest like the one illustrated in this video. It would be devastating to be present at any low level when the rock entered the water and when the backwash occurred. You could not survive it unless you were safely above its limit, but a crested wave that no one noticed? I don't think so. A wave that large, if it had resulted from the rock slide would have found exit at the mouth of the fjord and would have immediately lowered to a wave a few feet high until it got to open water after which it would have reduced itself to a foot or less and might not have raised an eyebrow when it got to Japan. I suppose it doesn't bode well for the next expedition if you don't maximize the size of the event that you're investigating on such scientific jaunts.
That would be so cool if a tsunami struck while they were there. They could film themselves surfing their way out!
Geologists are awesome! Fund them.
This seems like a total waist of resources. No one will ever receive the benefits of understanding precisely how rocks sliding into water works.
You don’t even know how to spell waste.
You seem like a waste of resources
Beaucoup de beaux discours, mais personne sur place pour filmer au moment des faits.
This shit is terrifying.
We don’t have any footage but we can talk about the tsunami… Lame :-) LOL good video though
No such thing as a "Mega [sic] Tsunami"; a thing is a tsunami or it's not.
How the FUCK did no one film it??
The one guy just said what caused the tsunami. Land slide into the water. Pushing the water.
Too bad it was not filmed.It could have called ahead.....
I would like to see a MAGA TSUNAMI!!!!
To bad no video 📸
These tsunamis don’t last very long though do they, I believe due to their wave form and the geography? But it would be damn impressive to see one captured on video. I remember the story if two American fisherman in a place like this and the same thing happened, and they actually rode over a massive tsunami. Shame they didn’t have video phones haha. They survived fine to tell the tale, can’t remember where they were though when it happened.
Sounds like the Lituya Bay tsunami
That's because the water was only 90 meters deep.
Though a landslide like La Palma collapsing into the sea will be devastating, it'll travel from Africa all the way to the Americas.
Some people have jobs that are more interesting than mine .
talking heads no 'mega' anything
Joe, you obviously have no clue of this area of Alaska and how massive this was, just didn’t get any coverage because it was in Alaska in a pure, remote non populated wilderness area here in Alaska! Your clueless! This was a massive mountain landslide that dumped huge amounts of debris into a narrow fjord and produced a huge surge wave that pushed through the bay, you as most are clueless about things that happen daily in Alaska, most can’t comprehend!!!
rockn roll , satellite photo. Why you have such a hard time understanding Alaska? Want one better? You tube lituya bay Alaska mega wave! Largest “surge wave”, ever recorded on earth, 1958, caused by a massive earthquake, trigged tons of rock and debris down a steep mountainside into the bay, pushed a wave across the bay and went up the mountain 1300 ft!!! Look it up, watch the vid, two survivors an Alaskan native and his son! To this day you can fly over it and see the scar line of how far up the wave went! Check out the vid!
Music spoils it. CRAP MUSIC ! Had to mute it.
Everybody there is a dr it's like too many chiefs not enough Indians
Too bad there's not something like a Vortex Cannon or sound Cannon floating out in the water facing towards the shoreline and facing away from the shoreline so that in an event of the earthquake or something they could be set off to counter uncommon approaching waves. Anyways of Their Own
WTF are you talking about? Bat shit crazy thoughts spewing outta yer head. Keep them to yerself.
Impressive video- and no climate change “soapboxing”
Who is paying you and why?

Wow. They get paid to see how this dirt/ ground moved n why it caused this wave. Let’s take a look at satellite images n see where the large amount of dirt came from.
