Thankfully, no injuries or deaths have been definitively traced to these past inland tsunami events at Lake Roosevelt. Let’s keep it that way. Only property damage (docks, businesses, boats, etc) have been recorded during past events. A photo exists of the tsunami wave right before it struck, but I do not own the licensing rights to the image in question which can be found on Facebook.
I was almost going to comment and say, See! I told y'all it wasn't an automated voice! It's called a cadence and good speakers have a distinctive cadence. 😌👍✨
@@robr135 no. AI is lazy and is a tool to make vids with zero knowledge or intelligence. It's searched from the web and auto narrated. None of those vids deserve views. It just takes from real people
I used to work on the orchard directly above these slides. They diverted a large Creek called Sherman Creek in the late 1800s and every year they saturate the soil for the fruit trees and hayfields above the slide areas. There are numerous slides all around the 100 + acre properties because of this. There is bedrock limestone and slate beneath the glacial till. The water from the creek irrigation saturates the glacial till, then it hits the bedrock and flows downhill and creates artificial springs downhill of the properties. Just thought this might be interesting info for y'all 😊👍🏼 Edit: I know this is also a natural phenomenon as there are other slides up and down the lake Roosevelt reservoir usually occurring wherever there are natural springs. I guess that the water table from the lake meeting with spring water output is a recipe for small landslides 🤔
It's nice to finally see the real human behind these *_awesome_* geology reports! I'm not a geologist but I watch every one for their clarity, informative value, and never alarmist (but genuinely alarming when justified) content. I live in the San Francisco East-bay area so am particularly interested in activity on the San Andreas and Hayward faults, as well as the Cascadia subduction zone. Thank you for your dedication and excellent presentations, a true gift to UA-cam watchers!

I live in Washington too, on an island actually and I was really confused when I saw your video! Inland tsunamis aren’t anything I ever thought of as a possibility. Thanks for the great information.
yes! I live on Vashon island and nothing could ever convince me to live less than 50’ above the shoreline anywhere, especially in Puget Sound. I also had no idea he was in Washington state and I’ve been watching his videos for years! Sending this video to my ex because he always claimed it was an AI generated voice. We got into some stupidly heated arguments over that😂 I defended my geology guy so fiercely because I’m a rock nerd; I could not just let the AI accusations stand. Now I have proof!
This is going to be a fantastic Thanksgiving conversation. "Did you know we had a 30' tsunami the other day?" That's up there with the fun fact that we are the only state with a mountain range contained entirely within our border. Oh and remember my fellow Washingtonians, if anyone asks, the answer is yes, it constantly rains every day up here. Try California.
No doubt. I love living near water, too, and I had hoped to find a place where I can see the water from my house. Now I'm thinking maybe it's actually just fine I can't see any from here. Although I do have a tiny pond in my backyard. That's sounding quite sufficient because no tsunamis there. Lol
@@amberackerson5916 amber check out the Thunderbolts Project. specifically the research into how all this geology was formed. electric universe theory put forth by wall thornhill. the real was our planet and solar systems geology was formed is absurdly spectacular. let me know what you think.
As usual, this video is outstanding in it’s educational value! I had no idea of the glacial makeup of the landslide area, or why the dam on the lake could contribute to landslides. Thank you so much for your hard work and the excellent teaching you do!

I live in Southeast King County and haven't heard anything on the local news outlets about this. I wonder how long it took the water to stop sloshing back and forth between the river banks? I took a Geology 101 class at Green River Community College in Auburn a couple decades ago, and am fascinated by the glacial deposits all over the place. Indeed, I am on a moraine and I constantly mow glacial river rocks in my back yard. Professor Nick Zentner from CWU covers a lot of this stuff on his channel also.

Lituya Bay in 1958. A 1600ish foot wave formed from........ A rock slide caused by an earthquake! Interesting that it only took a couple lives too. Had it been any where even sort of remotely populated... It'd have been a different story. Stay vigilant out there! I used to live and work out of Yakutat, so I feel ya about the feeling of being quite aware!
Same for me. I left the end of 2002 and ended up in NM in early 2011 for work. If my dad hadn't left the Air Force and gone to work for Boeing, I would have been born in Albq. I love it here.
I read the title and said “Wait, I live on Vancouver Island which is practically in Washington State and I never heard anything about this”😁 Thanks for this! Very interesting.
Took the words right out of my mouth. I, too, live in WA and did not hear about this! On a side note, if anyone gets the opportunity to tour the dam and watch the evening laser show, DO IT! Rock climbing up there is also good as long as you stick to the stable basalt AWAY from the water's edge. 😊
this reminds me of that tsunami somewhere in the italian alps. they had built a dam and when they were filling it, they noticed that the slope on one side of the lake was slipping. eventually the whole side of the mountain collapsed and created a tsunami that went up the other side of the lake, flooded a village and killed lots of people.
Love this channel. Always boggles my mind how much the Earth is moving even when its a relatively small event like this. Massive swathes of the ground moving and sliding away is crazy to think about. Most amazing is the power of water to cause it. Cheers.
Thank you for your video. You may know that there are similar landslides on high back waterfronts around the Islands in Pudget Sound. Camano Island and Whidbey Island have both recently had landslides and eroded coastline. King 5 news did reports on the landslides in Langley, Washington. The city cut down trees along the high bank waterfront coast to improve the view. Then there was a land slide, and part of the cliff slid off into the sea. The roots of the trees had been stabilizing the hillside. Once removed, the hillside collapsed. I went to visit an Elder on Camano Island who had been born in the House that he was living in. He told me that they had to move the house back 150 feet in 1969 because the high bank waterfront hillside was eroding at the rate of approximately 9 inches a year. He was 96 years old when I visited him in 2000. He said the house was now 20 feet from the edge of the cliff. I saw the house in person and it was indeed 20 feet from the cliff. He showed me an album and photographs of the house with the progression of the eroding cliff bank and loss of the land over time. I think it is important for those of us who live in coastal communities to be aware that earth quakes can cause Tsaumis and landslides very quickly. Get the national weather service emergency alert system app on your phone to alert you in the advent of a Tsaumi. And when there is a tremor or an earthquake look up the Pacific Northwest My Shake earthquake app that will tell you where the events orgin is. Stay safe everyone. Thank you again for your video.
Woo hoo we get to see you ! Love your accent. Where are you from originally. Oh, by the way, Love your channel. So so informative. Brief, but packed with info.

Words are insufficient to convey the depth of my disappointment that an "American football field" was used for scale, yet the volume of the displacement was not expressed in Olympic swimming pools.
Perhaps it's time to scale water volume by increasingly larger volumes, starting with toilet flushes, moving up to bathtubs and so on. I really can't visualize the difference between Hollywood swimming pools and Olympic pools.
Thank-you for all your geological videos. I know about the huge wave that occurred in Alaska in the 1970(?)’s on a narrow islet. This is the first time I have had heard of a tsunami occurring on a reservoir hundred’s of miles away from the sea. I think that there recently was another landslide in Greenland. I hope that the Islands of Hawaii are doing some planning for this!! I believe large chunks of the Big Island have fallen into the ocean in a similar manner!!
You've picked up the modern mispronunciation of Roosevelt: the "Roos" part was always pronounced "rose" but people nowadays mispronounce it as "ruse." Something similar happened to the Cheneys, and now they're stuck with it!
@@geckoman1011 That's more a local knowledge thing. Someone asked me for directions to Puyallup once but the syllabic stresses were off and it took me a couple listens to figure out what they were trying to say. Most people outside the area wouldn't need to know how to pronounce city names, even one as big as Spokane. Roosevelt is more widespread on account of the historical figures that served as the eponym of many things with that name. A shift in pronunciation might imply a decrease in awareness of those figures.
We've seen this at Lake Powell (res) on the AZ border due to the same reasons. The wave wasn't terribly destructive since it's surrounded mostly by high clifts. I'm sure the marinas got a little rocking.
My roommate and I were learning about the Wilkes Land Crater in Antarctica. The documentary said it produced "mile high tsunamis" here on the West Coast of the US. Just for fun, would you someday talk to us about what that would've been like? How far inland do mile high tsunamis go anyways? 🤔🌊
I've watched a few Geology Hub video's and appreciate the entire presentation. But this one... I've never laughed at so many comments and replies. I tapped "like" on more comments and replies than I ever have on any other channel. My kind of community!
Have you ever done any research into Atlantic Highlands, NJ? Not long after the 2011 Virginia earthquake, the elevated shorelines of Atlantic Highlands and its neighboring town Highlands started experiencing landslides. Although not large in area, these landslides damaged homes and disrupted traffic on the Henry Hudson Trail, a nature trail traversed by hundreds of people daily. Maybe more concerning is that these cliffs and slopes that make up the area are directly across the Raritan Bay from NYC. Mount Mitchell Scenic Overlook in Atlantic Highlands, the highest natural elevation on the Atlantic Seaboard from Maine to the Yucatán, sits within a mile of each landslide’s location. As a public worker at the time, I mentioned to the USGS surveyor who came to assess the impact that we had never experienced these landslides prior to the above mentioned earthquake. He didn’t dismiss the idea but seemed to treat it more of a curiosity than something noteworthy, and to be fair, we haven’t experienced any landslides since 2012. It’s something that’s always lingered in my mind, and what better place to mention it than here
Dead on to both connect the dots and be concerned. I live near enough to the USGS HQ and the USED TO BE a reliable source and resource for investigation of risk newly exposed.... Sadly I think most of that leadership and staff are now long gone, as the last 20+ years have been strangely uninterested in real geologic works govt security and pushing narratives out 😐
This was in my YT suggestions and I had the same reaction as you...wait, I never heard about a Tsunami here in WA! What an interesting video...explained very well and I got to learn some new things (glad no one was hurt too!). I like geology topics, but don't read up on or watch enough videos about them, so you just got a new subscriber. Look forward to checking out your other videos and future ones to come.
I lived in Colville in 2008 thank you for this video I had no idea this even happened I heard no news hard to believe that a 30 foot tsunami would happen on Lake Roosevelt very interesting
i doubt that's the only lesson. something this big doesnt usually only affect one thing: homebuyers. there are probably global consequences for each flaw that spread slowly. i don't want to call the dam a flaw. but it's probably a flaw. built 1942. that era wasnt known for bright americans running plants. unless by bright you mean nuclear explosions. 🤷♂
There have been 3 significant landslides in the Spokane Arm of Lake Roosevelt in the past 10-15 years. I always think about these while I'm fishing right next to the steep bluffs and hear rocks trickling down the cliffs the entire time.
"Since 1967" My response was that this has happened before? Thank you for the information. I only recently learned about the singing stones park in Pennsylvania. I would love to hear your take, if you are looking for subject matter. Happy Thanksgiving!
My take, those are rock gnomes. There are a lot of 411 cases associated with them. They can lure people in and they are never seen again. Or so they say.
As the water level drops in Lake Powell, that soft saturated sandstone crumbles easily. I was camping in Escalante canyon one year and there was a big landslide about a mile away. I'm sure it happens fairly often, but you rarely hear about it.
Washington has been the place of several slides. They include the Oso mudslide, the one that occurred with the Mount St. Helen's eruption, and the Wellington avalanche in 1910. At least the ones regarding Lake Roosevelt haven't killed anyone.
The whole state is dotted with high risk landslide zones, largely from our glacial history. This one would very likely have had fatalities if it happened in the summer. Boats out fishing and recreating, full campgrounds along the shores, etc…
Honestly never gave thought of such a subject as this affect inland water sources. But the explanation and graphics is interesting. This could be a subject to explore more in future videos.
Thankfully, no injuries or deaths have been definitively traced to these past inland tsunami events at Lake Roosevelt. Let’s keep it that way. Only property damage (docks, businesses, boats, etc) have been recorded during past events. A photo exists of the tsunami wave right before it struck, but I do not own the licensing rights to the image in question which can be found on Facebook.

We've seen this at Lake Powell (res) on the AZ border due to the same reasons. The wave wasn't terribly destructive since it's surrounded mostly by high clifts. I'm sure the marinas got a little rocking.
My roommate and I were learning about the Wilkes Land Crater in Antarctica. The documentary said it produced "mile high tsunamis" here on the West Coast of the US. Just for fun, would you someday talk to us about what that would've been like? How far inland do mile high tsunamis go anyways? 🤔🌊
I truly enjoy your content for its clarity. You make me feel smarter just watching your videos.
BTW, nice to see the face behind the voice.
I've watched a few Geology Hub video's and appreciate the entire presentation. But this one... I've never laughed at so many comments and replies. I tapped "like" on more comments and replies than I ever have on any other channel. My kind of community!
Have you ever done any research into Atlantic Highlands, NJ? Not long after the 2011 Virginia earthquake, the elevated shorelines of Atlantic Highlands and its neighboring town Highlands started experiencing landslides. Although not large in area, these landslides damaged homes and disrupted traffic on the Henry Hudson Trail, a nature trail traversed by hundreds of people daily. Maybe more concerning is that these cliffs and slopes that make up the area are directly across the Raritan Bay from NYC. Mount Mitchell Scenic Overlook in Atlantic Highlands, the highest natural elevation on the Atlantic Seaboard from Maine to the Yucatán, sits within a mile of each landslide’s location. As a public worker at the time, I mentioned to the USGS surveyor who came to assess the impact that we had never experienced these landslides prior to the above mentioned earthquake. He didn’t dismiss the idea but seemed to treat it more of a curiosity than something noteworthy, and to be fair, we haven’t experienced any landslides since 2012. It’s something that’s always lingered in my mind, and what better place to mention it than here
Dead on to both connect the dots and be concerned.
I live near enough to the USGS HQ and the USED TO BE a reliable source and resource for investigation of risk newly exposed....
Sadly I think most of that leadership and staff are now long gone, as the last 20+ years have been strangely uninterested in real geologic works govt security and pushing narratives out 😐
just look forward to you so much!!❤
This was in my YT suggestions and I had the same reaction as you...wait, I never heard about a Tsunami here in WA! What an interesting video...explained very well and I got to learn some new things (glad no one was hurt too!). I like geology topics, but don't read up on or watch enough videos about them, so you just got a new subscriber. Look forward to checking out your other videos and future ones to come.
I lived in Colville in 2008 thank you for this video I had no idea this even happened I heard no news hard to believe that a 30 foot tsunami would happen on Lake Roosevelt very interesting
I love your videos, very informative i cant stop watching lol
Very interesting! Nice video as usual!
It's about time we see who this man
Interesting. Good video. Thanks.
I feel like whenever you show your face its always during the most random videos. Kinda funny.
Thank you for this interesting explanation. I never knew such waves could form inland!
Finally got to see your face! You have a very strange voice..not in a bad way😊
It's distinctive. ✨
@@dianepusateri5841 he's a good egg 👍
@WildAlchemicalSpirit yes..that a good description.
The lesson to take away: A lake shore next to the mountains isn't necessarily in ideal place to set up your home.
i doubt that's the only lesson. something this big doesnt usually only affect one thing: homebuyers. there are probably global consequences for each flaw that spread slowly. i don't want to call the dam a flaw. but it's probably a flaw. built 1942. that era wasnt known for bright americans running plants. unless by bright you mean nuclear explosions. 🤷♂
Excellent! Thank you for this!
Great video well done
I actually live in Grant County, maybe 45 minutes- and hour from the dam and had no idea this happened. It's fascinating
You have a talent for taking the fear out of what sounds like a potenial horror.
😃👍
Thank you for doing what you do! 🙏❤️🙂
There have been 3 significant landslides in the Spokane Arm of Lake Roosevelt in the past 10-15 years. I always think about these while I'm fishing right next to the steep bluffs and hear rocks trickling down the cliffs the entire time.
Thank you. I live 7 miles away
Fascinating. Thanks.
Crazy! I was just fishing there a week ago.
I was on the shore a few hours after it happened completely unaware of what had occurred earlier
"Since 1967" My response was that this has happened before? Thank you for the information.
I only recently learned about the singing stones park in Pennsylvania. I would love to hear your take, if you are looking for subject matter.
Happy Thanksgiving!
My take, those are rock gnomes. There are a lot of 411 cases associated with them. They can lure people in and they are never seen again. Or so they say.
This happened right next to our ranch. Thank goodness no one was killed or hurt. It crossed highway 25! And the Colville River ran backwards.
Nice to see you in a video again Tim!
love your videos
I've been waiting for this!
As the water level drops in Lake Powell, that soft saturated sandstone crumbles easily. I was camping in Escalante canyon one year and there was a big landslide about a mile away. I'm sure it happens fairly often, but you rarely hear about it.
Thank you for the video.
Washington has been the place of several slides.
They include the Oso mudslide, the one that occurred with the Mount St. Helen's eruption, and the Wellington avalanche in 1910.
At least the ones regarding Lake Roosevelt haven't killed anyone.
The whole state is dotted with high risk landslide zones, largely from our glacial history. This one would very likely have had fatalities if it happened in the summer. Boats out fishing and recreating, full campgrounds along the shores, etc…
Ooh! I like this format
The scallops on the shoreline are impressive. All that sediment will eventually raise the lake floor level since it can't move downstream past the dam
Honestly never gave thought of such a subject as this affect inland water sources. But the explanation and graphics is interesting. This could be a subject to explore more in future videos.
