- This movie shows a physics-based computer simulation of a Mega Tsunami that
occurred in Lake Tahoe about forty thousand years ago. The tsunami parented from a massive landslide on the Lake's west side. Imagine such a event today!

One interesting aspect to a Tahoe tsunami is that the lake has an outlet. Each slosh would send a huge flood surge down Truckee River, devastating anyone downstream. Those surges would take water out of the lake so each future slosh would have less water than the previous one, and the lake would settle at a lower level than it was before the collapse. It would refill normally of course, but for a time the water level would be lower.
When I was 6 years old, I did this in my bath tub... it was total devastation for my sisters cat. The wave slowly built, breached the dam and that little bastard never came into the bathroom again.
Great simulation. The only things; the tsunami you’re talking about is not a tsunami, but a Seiche Wave as this phenomenon exists only in small bodies of water, i.e. lakes, reservoirs, etc. and the debris you speak of are rocks and dirt, not blocks.
Thanks for creating!
Very much appreciate your work.
I'll create a video response that includes a stereo 3D visualization of the Lake Tahoe Tsunami using Steven Ward's data, which he generously furnished for Lake Tahoe in Depth. His Mega-Tsunami video here provides more detail than that earlier version, but the whole movie is a good orientation to science at Lake Tahoe. It is shown at the UC Davis Tahoe Environmental Research Center, Incline Village, in stereo 3D.
I enjoyed the cute snippy attitude of the text narration.
Can't stop watching these videos they are great 😊
Scary stuff. Well done 👍
Great video… Really good work that you put into this thanks for the post
Although it is commonly believed that Lake Tahoe was formed by the collapse of a volcanic crater, the Basin was actually formed by the rise and fall of the landscape due to faulting.
...
Watching this, I feel like going swimming now
Amazing computer simulation.
Large displacement causes a seiche.
Actually Mt. Pluto made that debris when it errupted due to 2 earthquake faults besides the lake over 2 million years ago. :)
it would be neat to use Unreal Engine 5 to create a more photoreal depiction of what happened.
Thank you for sharing your strategy sire.
Not all that big of deal prior to humans putting structures all around Lake Tahoe.
A narrator would have made this soo much better
