3D-print demonstrating a rotational landslide at it simplest. Amazing how much you can actually communicate with such a simple model: Rotation, self-stabilization etc.

Working towards making more complex models and share the blueprints so they can be used in outreach.

good point - though a +400 m runup for that geometry and size of landslide would not be surprising

And from what i can see circulating in here of post event sat images it looks like a +400 m vertical runup near the source.

Looking at the runup on the opposite shore to the s of the scar and reading an approximate elevation from ArcticDEM it looks like we are close to the world record for highest tsunami runup (524 m Lituya Bay).

Crazy (horizontal) runup from the large landslide into Tracy Arm fjord, SE Alaska. This is 20 km out the fjord and the wave reached up to 400 m into this side valley. notice how the vegetation was only wetted for the most part (pixels still red) and only the mouth of the river is destroyed.

It has been a busy couple of days! There was a large landslide and tsunami in SE Alaska, in Tracy Arm, Sunday morning. Luckily, no injuries or casualties were reported. This region is outside of our current landslide coverage, but we were able to get a quick location after hearing about the event. 🧵

SPEECHLESS BEFORE / AFTER #BLATTEN

The magnitude of destruction after the 3:24 pm collapse of Birch Glacier is immense! 😱

All the forest has been razed and the ice/wood/debris dammed the Lonza river 🌊

Some buildings of Blatten are buried 🏠

Seeing Blatten buried again and again, from every angle...

Properly staggering! 😮😱

Thanks for sharing Mike!
...and it was so great fun too! We all did it next to our "other work" for the love and thrill of it.

What the current administration in the US is doing to science these days really puts this into a new perspective.

Making the rounds once more. This amazing story and collaborative effort that I was lucky enough to lead (in a very flat structure!) also still amazes me.

Mike Sowden @mikeachim.bsky.social · May 12

...it concluded since the landslide was triggered by the melting glacier, and since *that* happened due to rising global temperatures...

This was a signal - and a warning - from our rapidly changing world, heard in every single part of it.

Best we listen up.

A rockslide-generated tsunami in a Greenland fjord rang Earth for 9 days

Climate change is increasingly predisposing polar regions to large landslides. Tsunamigenic landslides have occurred recently in Greenland (Kalaallit Nunaat), but none have been reported from the east...

Oh, this is another news-to-me one for me to notice. Bedrock slide into fjord southwest of Mount Moresby. Look at the wave runup on the opposite fjord wall!
@mabrideau.bsky.social @watershedlab.bsky.social @geobrentatlarge.bsky.social

Google Earth view of fjord, 2011, no big landslide. No tsunami slosh.

Google Earth view of same spot 2024. Big bedrock slide on one fjord wall, big tsunami slosh directly opposite on the other wall of the fjord. Looks like it ran up 60 m vertical or so directly across from the slide!

all this is of course speculative and needs to be tested further
