"The Scale of WHAT we are dealing with is UNPRECEDENTED" Alaska Earthquake Center TSUNAMI WARNINGAdded:
Alaska mega tsunami warning. And this is not just on paper or not just a theory.
This is a warning says what already happened will happen again. And I'm talking about a tsunami that just happened last year. And listen to this.
1,580 ft high, guys. This is around 481 m. Tracy Arm. The Tracy Arm mega tsunami in Alaska. The warning that we're getting right now, that is a terrifying warning from Alaska. Um, we remember, I've reported about this last year, a mountain slope collapsed into the Tracy Arm Fjord and that's like a bathtub effect. And the animations that they have now that they just released there are absolutely amazing because they show you what has actually happened when this mountain side uh collapsed. And this was happened near the south sawyer glacier.
So basically this was something like blutton in Switzerland that we also remember last May but not only the mountain and the glacier collapsing just into that valley and burying the village of Blutton that whole thing came down into the water. And if you displace water and this is a fjord where you have the steep slopes on all sides where is the water going? That's why it created this tall tsunami, right? It sent this tsunami 1,580 ft high up the wall of the fjord. And this is taller than the Empire State Building. This is taller than the Cien Tower or the Eiffel Tower.
And uh it's just a little bit below the highest tsunami ever recorded. And a friend of mine sent me a picture talking about his Alaska trip a few years ago.
And I looked at the picture and I'm like, you were lucky because this was a spot of that landslide. You were just lucky that this wasn't happening when your ship was actually in there. And he was very surprised. I'm like, really? Yes, really. And what I'm about to tell you right now is even more important. And when we look at the new data that we have, but do me a quick favor, guys.
That doesn't cost you anything. Leave this video a like and a hype. Share it with your friends. It helps my channel and it doesn't cost you anything. So, the part where I say that should make everyone stop because Shizzy could have hit the fizzy even worse than it did with with that landslide, right? Let's imagine that this happened in a fjord used by cruise ships, sightseeing boats, and kayakers. If you're a kayaker, uh, yeah, that forget about it, right? You probably sit on a mountaintop on the slope of the other side if that really happens. So, more than 20 vessels, including large cruise ships carrying thousands of passengers, can travel through Tracy Arm nearby Andicott Arm on like a normal summer day.
So, that's what makes this so dangerous.
So, and the only reason this did not become a mass casualty event or a disaster is the timing when this happened. Um, it happened early in the morning around 5:26 a.m. So, that is good. Good. No cruise ship was sitting in this upper fjord when that wave hit.
But the warning that we're getting right now, the scientists are giving us a clear warning that slopes like this are becoming more unstable while the glaciers are retreating and the perafrost is degrading. And we have many fjords like this in Alaska, in Norway, but also the mountains like in Switzerland. We've we've got problems in Italy and Austria, in Germany. So the real question is definitely not could this happen again? It's just a matter of time. it will happen again. So the real question that we have to ask what happens if the next one happens at the wrong hour when the ships and people are in there because in a narrow fjord there is nowhere to run and especially if you're on a boat. Tracy Arm that location is in southeast Alaska. It's about 50 miles or 80 kilometers southeast of Juno. Um it is one of those places that do look almost unreal, right? Beautiful tall cliffs, deep water, glaciers, waterfalls, um ice floating through the fjord. Um exactly the kind of place people pay a lot of money to see it from a cruise ship.
Right. So, but that beauty unfortunately is also the grave danger that lurks in this area because these fjords are carved into these steep mountain walls and some of these walls are being held in place by glaciers. Not permanently, not safely at all, just temporarily. And when the ice retreats, the mountain can lose support.
And that is what scientists actually believe what was happening when the Tracy Arm landslide hit. That a a glacier had been buttressing the slope, holding it back, pressing against it, so to speak, supporting it like a frozen wall. But then the South Sawyer Glacier retreated rapidly. And when that support disappeared, the rock slope was basically left exposed and unstable. And then unfortunately last summer on August 10th, 2025, that mountain failed and about 64 million cubic meters of rock and debris collapsed. And uh that's not a small landslide. That is a huge mass of mountains suddenly falling all together into that narrow body of water displacing the water and when that much rock and material drops into a fjord that water has to go somewhere. You can try it in your bathtub or if you have a very voluminous person jump into a pool.
You know what happens right? It does not spread out like it does for example in the open ocean. Right? This is really really different and it happens so fast.
The wave arrives so fast. So the water that is displaced is trapped between these steep walls. So the only way to go for the water is going upwards, right?
It races across the fjord and it climbs the opposite cliff. And in this case the runup reached about 1,580 ft. those almost 500 meters almost half a kilometer. So this is why this is called a mega tsunami and it's not because it has crossed an entire ocean like 2011 the Japan Tohoku earthquake not because it looks like a Hollywood uh wall of water that is hitting a city.
Um, no. It's called that, but because it's locally, the wave climbed higher than almost any tsunami ever measured.
And this is where um what I'm about to tell you now gets even more intense because computer simulations showed a breaking wave about 330 ft high. That's roughly 100 meters racing at more than and now listen to this 150 miles per hour or 250 kilometers per hour when it's slammed onto the opposite shoreline. So a 330 foot breaking wave inside a narrow fjord that is almost impossible to survive. Um if a vessel is in there is close to that wave. I would say impossible. I would leave out the almost. So a cruise ship in the wrong place would not simply um ride that out like a normal swell. You can ride out tsunami waves if you're out in the open water, but they're nope. That's why we've recently seen it when there was this earthquake in Japan and that tsunami warning and the sirens were going off the ships that could in the harbor. They were driving out. They were going out to open water. But in that fjord, the cruise ship, no time. No time. This is not an ocean wave rolling gently under the hull. This is a violent displacements of water, rock debris and currents inside this confined channel.
The wave also strips vegetation from the walls. All the trees, we saw that aspy arm landslide. All the trees were gone.
Um, it throws water high into places.
Water should actually never reach. So, it sends surges down that fjord and then the whole fjord can basically keep slushing. So, like I said, the water in the bathtub, but on a much more giant scale. And that sloshing has a name.
It's called a seash. And in Tracy Arm, the water movement lasted long after the first impact. It was not short-lived.
So, people far from the actual landslide still noticed strange water behavior. Um there were kayakers near the south the mouth of the Tracy arm. They reported water sweeping away their gear. They were sleeping on the island and the water reached their tents and was taking their stuff away. They were really really lucky. So also the NOA tide go in Juno recorded tsunami waves far from the landslide even though the main destruction was just local thankfully. But they also knew the water was rising. Um, and I think that is actually one of the most important points. Um, a mega tsunami in a fjord is not all is not always about this one giant wave um that is traveling across the Pacific. Yes, it can be extremely local, but inside that local zone, it can be very catastrophic. And this is why Alaska has a special problem. We have to name it. Um Alaska is full of these steep mountains, deep fjords, glaciers, lots of earthquakes, Pacific ring of fire, landslides, uh cold region slopes that are now changing fast. So the geoysical institute actually is giving us a warning um that the likelihood of similar large-scale events has increased across the north as the the glaciers retreat and the perafrost degrades. So, my question is, should we still let the cruise ships in there? Is that still Does that still make sense? I'm not so sure about that.
Um, let me know in the comments. Would you go? I wouldn't. Sorry. I would just rather fly over it or something like this. So, the risk in Alaska is not only from the earthquakes anymore, that earthquakes might trigger some landslides or slope collapses, right?
Um, the mountain can fail by itself, and that makes it of course even more unpredictable.
um a full mountain slope can collapse into the water. Um a glacier can retreat just enough to remove the support, right? And that tsunami can happen before anyone has time to understand what has changed. But that Tracy arm landslide, we have learned from that. It gave scientists something very, very important and it's called clues. Very important clues. Um the study that was now released and conducted about the Tracy Arm landslide found localized seismic signals that began days before the slide. And days that is good. That could matter for the future because if some slopes make subtle seismic noise before they actually fully collapse, maybe scientists can one day build better warning systems. They will not be perfect. It's not guaranteed, but better than nothing, right? They do have some measurements in place at some steep slopes where they know they have already started to crack, but there are slopes that can come down completely as a surprise.
So these systems could make the difference actually between a near miss or an actual disaster because in Tracy arm the timing saved lives that it was so early in the morning right 526 but few hours later boats kayakers and cruise traffic would have definitely been in that area.
So, the University of Calgary actually described it as a near miss and said at least at least six cruise lines have altered their Alaska itineraries because of the remaining hazards in the Tracy arm fjord. And I think that is smart.
So, think about that again. This was not a prehistoric event that they have discovered in the rock layers. This happened last year in a modern tourist area in a place where people go for glacier viewing, right? And and now even the cruise ship routes are being changed because of the hazard that is still there. The scar is not go gone and the slope is not magically safe right now.
Actually, the USGS tells us steep mountainous landslide areas remain unstable for years after an initial landslide and continued rockfall or smaller landslides from the exposed scar area could still hit the water and create future local tsunamis. So, when we ask is Tracy arm safe right now, the honest answer is the area is still being watched because it remains hazardous.
And again, this is not only about Tracy arm. The same pattern exists in other fjords that have glaciers especially, but even without glaciers. Now, let's compare this with the most famous mega tsunami in history. Also, not that long ago, 1958, another Alaska landslide generated in the Latoya Bay um created a mega tsunami with a runup of up to 1,730 ft or 530 m, the highest known tsunami runup ever recorded. And then Tracy Arm last year is second after that. That's why this is not a random landslide story or a random warning. Um this this is serious and the failure can sometimes be sudden. And the researchers tell us this event was very surprising because like unlike some giant rock avalanches that that show slow movement for weeks, months or years. Even Blutton did show something few days before it happened.
Trace your arm did not show this obvious long warning pattern um that you might expect. It did not. There was only minor seismic noise so slight it it it may not have caught attention and this is the absolute nightmare for warning system.
Some slopes may advertise their failure good but others may stay and did stay quiet until they collapse.
But the good thing is after Tracy arm the scientists now have rare data. They have reconstructed the event. They have used satellite images, seismic data, field surveys, eyewitness reports, and computer modeling that helps to study these events. So, I hope you found that interesting. Um, I'm putting some other very interesting videos here in the end screen and I hope to see you there in a second, guys, because so much is going on and strange things are absolutely going on with these earthquake swarms in Nevada and three right now that they they keep coming and they are so clustered near three secret sites. Area 51, Area 52, Tonopa nuclear test range, um, Navy.
Is that a coincidence? Of course, we're asking that question when we look at the recent situation in the world. I have dissected that for you. Check out the video in the end screen. I see you there hopefully. Stay safe, guys. Bye-bye.
