We also didn't expect a hurricane to devastate Lake Lure and Chimney Rock, NC hundreds of miles from the coast. The Earth and its weather are fascinating, but dangerously so.
As a Swiss who loves to travel to Japan regularly, I am pleased to hear that from now I don't need to sit 12h in an airplane to start fearing earthquakes and tsunamis, I can do it right from the comfort of my own home!
Very interestng video. Thanks! Would you please do a video explaining MMI Shaking and "acceleration"? You've mentioned those point in the last couple of videos.
One problem with tsunamis, apart from the fact that people tend not to expect them, is that there is hardly any warning time because everything is so close.
All of these shown places, are glacial "U" shaped valleys, which have a high angle of repose valley slopes. They are more prone to landslides that detach from the slope, rushing down into the lower valley, which can be either lakes or flat occupied villages. Tsunamis are then obvious dangerous areas that need to be known, and have mitigation procedures in these areas.
I'm curious as to why Olympic-size swimming pools is so often used as a metric. No biggie; you're not the only one who uses it. I just have no idea how much volume an Olympic-sized pool has as I've never been to a swimming competition.
It's because people have trouble to visualize the volume of 1 million cubic meters and above. Actually, an Olympic pool is 50 meters long, which is twice as long as a regular swimming pool. They are also quite wide as they need place for 8 swimming lanes and a buffer zone on both sides. They are also pretty deep (3m or so) over the full length of the pool...
Are you planning to also make a video discussing the Flims landslide in central Switzerland, which occurred ~10'000 years ago and displaced 12 km^3 of material?
Didn't know about that lowest elevation. I grew up on the Great Plains of Alberta, Canada at 3400 feet or 1032 metres. Live at sea level now. Really want to go home to the dry, high, clear blue cloud-scaped sky and the Rocky Mountains glittering on high. Thanks for the show. Cheers!
As a semi-regular visitor to Lake Luzern, this is fascinating to learn about. Are there any records of similar incidents concerning Lake Thun and Lake Brienz? These were originally one lake, but have since been separated into two by deposition of sediments washed down the Lutschine River from the Jungfrau mountain region immediately to the South. The towns of Interlaken, Matten, Unterseen and Bonigen now stand on this intermediate area of ground. Lake Brienz is now slightly higher than Lake Thun, partly due to a large wier in Unterseen, which now supplies a hydroelectric power station beside the River Aare.
Awesomeness It would be cool to see this channel explain the yungay debris flow from the 1970 ancash peru earthquake, or armero and nevado del ruis lahar in 1980s
It would be interesting to look at lakes which are exposed to landslide risk but are also dammed. A wave of several meters overtopping a dam would be very worrysome I imagine.
A sudden large movement of one of the various strike slip faults behind building mountains throughout the Alps region might also do it to one or more of the Swiss lakes.
Living 5 miles from Lake Michigan's Eastern shore I had considered, because I'm strange, that the only chance of a significant tsunami was a strike from a significant asteroid on the lake. In which case a tsunami would be a minor problem in comparison. I don't think there is any land adjacent to any of the Great Lakes with the height or mass or instability which could cause a slide and tsunami. Perhaps Lake Superior but I doubt it.
If an event like this is going to happen there today its gonna be a desaster, because there are uncountable amounts of live ammunition dumped into all lakes in switzerland.
Can these tsunamis be mitigated before they occur such as blasting the mouth of that river as an example? Secondly, what was the causation of that large earthquake that you mentioned at the beginning of this video? 🤔
@@scrappydoo7887 I like your response. I think my point was that we should learn from these disasters and try to find ways to migrate them the best that we can but though I’ve been through more tsunamis that I can count on one hand, no one is a true expert on them with maybe an exception of my uncle, Gerald Fryer, who retired from PTWC almost 10 years ago and has been traveling so much that we don’t hear from him anymore. I just don’t think we have tried to migrate anything as far as disasters goes with maybe the exception of hurricanes and tornados, if that’s only in terms of preparedness. Granted, the Japanese Gov’t funded and built a 5.7m wall around some of their coastal towns but forgot to take into account that the entire coast would drop several meters and allow the tsunami to flow right over them. It is my hope that as technology advances, we will find ways to migrate at least some of these causes and be able to act on this information. My point was to start a dialog with my first post and that helped to get the discussion going. So thank you very much for your response and response time. 🤙🏻
Switzerland has quite frequent earthquakes, due to the stresses from Africa slamming into Europe and piling up the Alps. Usually they are small but there have been a couple of big ones in historic time.
Day 19 of requesting The Meers fault in Oklahoma and talk about other intraplate faults and how large earthquakes can hit away from plate boundaries Also this is an interesting topic
You'll talk about this but not Loess Hills,loess is an actual geological thing, and you have beat to death about displacement waves,Alaska and now Switzerland but not an actual geological action. I too thought Loess Hills were named after someone, but is a geological action, Loess Hills are a sight to behold how vast they are and was created by blowing sand,but let's talk about water displacement.

Or discomfort. I would imagine earthquakes and tsunamis are not cozy ideas. Time to dig deeper.
Thanks for covering this! I grew up in Geneva and the mountain tsunamis are fascinating.
Thanks for all the hard work on these videos!

Quite interesting.
Never disappointed.
Thanks as always, Geology Hub!
The most beautiful country on the planet, Switzerland.

Most of the world is metric

It's not lake lucern it's the Vierwaldstättersee/lake

It's a bit worse than that, actually. The Vajont Dam Disaster gives a good indication. ~200m tsunami that wiped out villages.
A sudden large movement of one of the various strike slip faults behind building mountains throughout the Alps region might also do it to one or more of the Swiss lakes.
This, but about Lake Tahoe .
here and there
My daughter is in Jr year at college and chose Geology for an elective - turned out the class was actually GEOGRAPHY. I'm bummed out big time.
Living 5 miles from Lake Michigan's Eastern shore I had considered, because I'm strange, that the only chance of a significant tsunami was a strike from a significant asteroid on the lake. In which case a tsunami would be a minor problem in comparison. I don't think there is any land adjacent to any of the Great Lakes with the height or mass or instability which could cause a slide and tsunami. Perhaps Lake Superior but I doubt it.
Sth about my country..can only be about Geneva and the Lac Léman
Lake Geneva does not exist. It is called Lac Leman. (The lemanic word refer to the whole geographic area and not only one tiny town around the lake)
When you put it in swimming pools it really makes sense
If an event like this is going to happen there today its gonna be a desaster, because there are uncountable amounts of live ammunition dumped into all lakes in switzerland.
Gravity + sloped earth + body of water = bad things
Can these tsunamis be mitigated before they occur such as blasting the mouth of that river as an example?
Secondly, what was the causation of that large earthquake that you mentioned at the beginning of this video? 🤔
No. Unfortunately the width, depth and wavelength of a tsunami means that it will roll over pretty much anything we can put in their path
* naturally that's going to depend on the severity of the actions that caused the tsunami in the first place

Also this is an interesting topic
We need vocabulary to distinguish between oceanic tsunamis and these lake waves.
Not necessary, both are caused by water displacement
@@ey3z4ya so is a flushed toilet.
