Buried by a 328 Foot High Wall of Water; Norway's Potential Future Megatsunami
Вставка
- Опубліковано 29 чер 2024
- At some point in the future, a massive portion of a mountainside in Norway will come crashing down into a fjord below, displacing water and generating a towering tsunami. If all 60 million cubic meters of material in this landslide were to crash all at once, it would create a true megatsunami with a maximum run-up height of 100 meters or 328 feet. In such a worst case scenario, more than 15,000 people would be placed at risk. Luckily, the hillside involved in this expected future landslide which is referred to as the Åknes landslide is one of the most monitored slopes in all of Europe.

I made this video as a response to a UA-cam comment, who reminded me about the existence of this (landslide caused) crack.
You should also cover the Mt Breakenridge threat for Harrison Lake in BC. It's very similar.
We have many cracks in this country, this being the most known and biggest. Every year we have smaller and bigger landslides, and several large ones is on the waiting list.
Can something be done to prevent?
- use dynamite to produce controlled landslide
- excavating somehow
@@keesvrins8410 not really, and who is going to pay for the damage that controlled action does?, im not paying for damage done by humans to prevent something that might not happen, this area could stil be stable in a few thousand years, or completely walk down the hillside with no major slip. Unfortunately nature is as fair as we get it
Would be interested in a follow-up video on what the options are with such situations--in terms of stabilizing the mountain, doing a controlled landslide, or leaving it alone to play out naturally. I assume the reasoning for not doing anything is usually cost, but would be interested to learn more.
The Norwegian film "The Wave" explores such a scenario. Really good movie!
yup watched it a few times, apparently it has slightly different titles for different markets.
Watch in with subtitles! The English language voice actors were horrible!
Excellent movie "The Wave"......
TV be Truth.
Dubbing movies should be illegal 😅
Thanks for all of your hard work!
As a Norwegian this is the only natural disaster we slightlly prepared for
Isn't there a Norwegian film about this or something similar?
Yes there is. @@surters
The Wave (Bølgen)
@@SpeedRebirth Thanks!
The massive landslide on the Columbia River would be a great episode. It formed a natural land bridge at what is now "The bridge of the Gods". An entire mountain sheared off and plugged the Columbia. That must have been crazy!
I will eventually cover this topic. That landslide occurred fairly recently, probably in the 15th century.
@@GeologyHub We North Westerners would love to watch your video about it. The event was probably linked to the last major Mt. Hood eruption from what I have learned.
Not a land bridge (the painting under the current toll bridge is mere fancy), but a dam, which was eventually washed away at the new channel.
That whole region is geologically fascinating. I would have loved to have seen what Wallula Gap and Dry Falls looked like at the height of the Missoula floods.
I believe the Yellowstone hotspot is actually a remnant of the Washington flood basalts as the North American plate moved over that mantle-plume.
@@oceantree5000 There's a strong possibility that there was a bridge for a very short time.
This is my fav youtube channel. Definitelty the most interesting.
And quite refreshing. So glad there's a place on UA-cam not filled with politics. 😅
Not too loud now,😗 don't want any of that action here!@@WildAlchemicalSpirit
Very interesting. One tends to think Northern Europe is safe from tidal waves. This is not the case. Scotland (6100 BC) The east coast of Scotland was struck by a 21 m (70 ft) high tsunami around 6100 BC, during the Mesolithic period. The wave was caused by the massive underwater Storegga slide off Norway. On 6 April 1580, there was a 5.8 magnitude earthquake with its epicentre on the sea bed close to Calais. Giant waves were reported, and hundreds of people were killed when ships were sunk by the waves and the low-lying coastal land around Calais was inundated by the sea. To name just two, but there are others.
Lets just hope that when it finally goes someone gets a good video of it
Before dying
This reminded me of the Storega Slide that inundated Doggerland. Have you done a video on that yet? Talk about scary supermegaultra tsunami!
Learned something of a place you don’t hear much about thank you prayers your way 🙏🙏🇳🇴🇳🇴🇳🇴
There is an 2015 Norwegian disaster movie called "the wave" it details this crack finally going and causing the tsunami disaster. it ties in with this perfectly.
This is close to where I live, some construction companies even get denied projects becasue of the future potential of the wave
One of the best disaster movies I’ve ever seen, The Wave, was made about this potential
Seems like at 1:12 the crack extends down to the water's edge. Or at least it seems so. If yes then the landslide, and resulting tsunami could be much larger.
It is a Sluff/Shale line/runoff.
I love the word "fjord" 🥰
Yes, it has such a good earthy sound to it don't you think? It feels satisfying to say it. Fy-ord. I could say it over and over! Now take the word 'tinny'. Eww Now that's an awful sounding word.
I live in a small town in the middle of Sognefjorden in Norway, and what it is described in this video can also happen here where i live. Though the hight of the tsunami is estimated to be around 60m when it hit land, so not as big.
Which landslide / hillside would be the expected cause in fairly close proximity to where you live? Ignoring the potential future hazard, it sounds like you live in a nice scenic location.
@@GeologyHubI don't know which one he is talking about but a similar thing can also happen near where I live. Where the structure "Pulpit rock" can fall into the fjord and cause massive tsunamies. The pulpit rock is a huge stone shelf hanging over the fjords with a big crack up top. Thousands of people go there every year, it could fall down any minute 😆
@@OneCatShortOfCrazyAre there any studies on this place? I was there a few years ago 🙈
@@OneCatShortOfCrazy I replied to him, does it now show up in the thread? 😅
@@FlugeTryne yes this reply shows but you never sid the name of the place as far as I can see 🤔
Thanks as always.
There's an entire movie on Netflix about this exact situation. It's nice to hear the science behind it a little more, thanks!
Do you remember what the movie was called?
@@KimiAvaryThe Wave
There is a Norwegian movie ,The Wave,2016 about this subject. A Hollywood-Style catastrophe… not very good thou but impressive !
There are many such slippages in Norway and in many other countries. In Norway, these are equipped with GPS equipment and measuring instruments that record all movements - The truth is that it will probably take several generations before it will collapse - but for safety reasons, monitoring is important. There are probably several possibilities to avoid such landslides - one is that you can start blowing up parts of this - over several years.
Hopefully some proper cam angles ready to catch the spectacular scene this is sure to be.
Very interesting, thank you!
Thanks.
You should make a video about the Steen River impact structure in NW Alberta. I think it would be a cool and interesting one.
Hmmm..... it sounds like a mini version of the famed Storegga slide.
Norway has the crack. US has Mount Rainier
The foremost geologist working on this dangerous mountainside said to one of Norway's largest newspapers in an article that such landslides tend to release within 60 years after they were formed. Since spotted first in the 60s it seems that it would now release very soon.
This is fascinating to watch but I sincerely hope that the people in the towns in the path of the tsunami will be able to relocate.
Most don't want too
They Made a Couple of Good Movies about it called "The Wave" & "The Quake"
As this is happening in the "inside" of a fold of land, it is likely caused by moisture.
Theory is that if surface water could be moved to the drier, outer areas of these land folds, it would reduce chances of land slumping.
All of Norway is like this. Then there is the Norwegian sea as well as the mid-ocean rift. Take your pick. Lots of tsunami triggers for Norway.
As the climate continues to warm, situations like this will continue to arise.
That’s not how this works, that’s not how any of this works
@@Da__goat Actually this is
The ones in Norway are not a result of recent warming but yea for sure more in Greenland and the Canadian Arctic and such.
How about a video on the Frank Slide if not previously addressed?
if I were in the towns affected by the tsunami, I would want to move to higher grounds.
I wonder if it would be possible to do a controlled demolition of the landslide? The towns could then be evacuated ahead of time. Maybe it would be possible to take down small sections at a time? If you know it's going to happen then why not try to control it? Wouldn't that be better than it happening by surprise in the middle of the night?
Technically yes it is possible on paper. This doesn’t necessarily mean it is a good idea as to slightest error could make things worse and no one would want to risk the blame for such. As a result, from a liability perspective no company (or their insurance company) would in my opinion want to risk such an attempt.
Clarification: I reread my reply and it might incorrectly sound like I am being rude. This is not my intent. I am merely answering your question and giving my opinion from my realist perspective.
@@GeologyHubBesides your well-researched and clearly articulated videos, this is why I love your channel. You're always very thoughtful and kind!
@@GeologyHub Let's have Tim do it. Then we can all blame Tim 😉
@@GeologyHub This has happened w/ controlled/prescribed burns in the Western US. Once such instance occurred in New Mexico near Los Alamos in the 90s. The winds shifted in direction & the whole thing blew into an uncontrollable conflagration.
i would like to request a specific topic! in Norways "Lysefjord" there once occured a huge landslide that now is a very popular BASE jumping spot and landing thanks to this happening
i saw a norvegian disaster movie about it ;p withy alpinist stuck in the crack, guy in radio, family going save children, etc etc...
its called "the wave". original title Bølgen
There are massive wave power turbines at the bottom of the fjord, to harness the stupendous energy released by the future landslide.
Is that true?
From the looks of the whole area, this could happen in a lot of places.
There is a Norwegian movie ,The Wave,2016 about this subject. A Hollywood-Style catastrophe… not very good thou but impressive !
Whoa
This reminds me of The Wave on HBO
The movie was based on this area :)
This type of landslide happened in Alaska causing a tsunami.
In mining this is referred to as a wedge failure. And yes it will fail. When it does it is very fast.
could the tsunami or landslide destabilize other slopes causing additional slides?
Possibility is there yes
That's a really good question. I assume (hope) there are monitors watching all surrounding slopes as well.
Someone else doubtless already mentioned this, but there’s a great Norwegian movie- w a geologist in the lead role, no less- on this very subject, called _Vannet_ (_The Wave_ på engelsk).
i am an norwigiean and live in oslo but if an tsunami comes i will just act alr because in 1987 i guess a 57m high tsunami came to norway killed only 27 people
Mankind being amazingly able, have any vikings started mining away the hillside from the top down? It'd be a long job but better to prepare then to hide the eyes and pray to Loki.
I think the one saving grace here is that if a catastrophic landslide and tsunami actually occurred, then the fjord's serpentine shape would help to rapidly dissipate the tsunami. If this mountain stood directly on the Atlantic coast, then you could have a horrific tsunami that travels for hundreds, or even thousands of miles away from the mountain.
For those who doubt, 1964 Alaska. These settlements are not a good place to be.
The generations of people who lived in those fjords for hundreds of years would beg to differ.
Or 1934 Norway. The very thing this video talks about happened, 20km from this location.
On an unrelated note, 328 is Trapinch's national dex #! 🐸
Like the movie The Wave?
Wait a minute.. The movie ''The Wave'' was made because of this scenario?
Yes, it has happened before
@@xwiick It didn't occur to me until I read about Fjord
I know hardly anyone cares, but are there any shipwrecks in the immediate area? If it was to happen we could use them to learn more about tsunamis given current conditions & ages.
I wonder if there's a way to preemptively induce a landslide (eg with exposives), but with temporary structures in place to shield communities from the waves.
not really, and who is going to pay for the damage that controlled action does?, im not paying for damage done by humans to prevent something that might not happen, this area could stil be stable in a few thousand years, or completely walk down the hillside with no major slip. Unfortunately nature is as fair as we get it
@@xwiick true enough. Tho that slab looks like it could come loose by a guy with a crowbar.
@@kdeulerLOL. But don't give them any ideas. Guys with crowbars are generally bad news. 😀
Could you use international standard units in titles too instead of american ones
I sounds similar to Himalayan tsunami of India, where unofficially 200000+ people died
time to open up a surf shop?
💀
This looks like future Turtle Mountain disaster.
😮😮 yikes 🫣👵🏻👩🌾❣️
Could they use a big tube of super glue?
Wow... What an awesome example of mass wasting!
Would it not be better to do a controlled dynamite destruction of that hillside?
No. who is gona pay for the damage?
@@xwiick As i understand it will happen anyway and will cause a lot of damage AND death. Why not use dynamite and save at least the lives?
It may even be blown up in stages and the damage will be limited. I don't know enough about this, but mining companies should be able to calculate this...
it could happen in 2 thousand years too tho. when it might not be a human issue. People living here know what to do and how much time they have when an alarm sounds
Was it in Italy that this happened?
It has happened in most parts of the world with steep fjords or mountains close to large bodies of water
So is this a betting matter? Or just a punt?
Mass is a terrible thing to waste.
Sounds to me, like the people living in that fjord should move.
The problem is there are countless other potential landslides possible around the world. How does anyone ascertain the risk level to warrant moving?
I would bet that people living in the East coast and Gulf of the US are at least at as high a risk if not higher from a hurricane. Or in eastern US away from the coast which is vulnerable to tornadoes or floods. Or in western forested areas from wildland fires. Get my point??
I would rather live in these mountains than any city. Death in a event like this would be quick, and there are early warning systems in place
Blast it.
Its over Norwegian bros

That AI voice sounds terrible.
No AI voice here. stop talkinng about things you don't know
Gonna be another Latuya bay disaster.

Guess there's not enough people living in that trench to warrant a solution... There are several in mind. All use the weight of water against water and gravity.
