Eclipsing on a giant paleo landslide in Svalbard with @watershedlab.bsky.social is verifiably the way to do it.

A 1771 antique map, a 3D print of a beautiful LiDAR DEM, a glaciotectonic complex, some giant landslides and one of my all-time favourite field sites: Røsnæs, Denmark. When it all lands on your desk at once 🤘🤯

A wonderful new paper (Shugar et al. 2026) on the 150 million tonne Tracy Arm landslide and tsunami will have profound but challenging implications for the management of risk in fjords around the world in an age of increased tourism and rapid climate change:- eos.org/thelandslide...

Elevated water table triggering an idealised 3D-printed rotational landslide. Complete with a Monopoly house on top. A paper, presenting six different 3D-printable landslide models, has now been submitted for review. Once it is published, they will all be made freely available. Get printing!

Tsunamigenic rockslide on your desktop? This is a scaled and simplified model of the 2017 Karrat landslide. I think it captures the dynamics of the tsunami generation quite well, though it is of course, very simplified.

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.

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. 🧵

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!

Greenland deja-vu. This is becoming the norm on high alpine and Arctic slopes worldwide. Are "we" ready for this and the larger-scale events lurking soon as we exceed mid-Holocene temperatures? These slopes will experience temps they have not faced in 100k years - maybe even 1000k's 😱 - indeed

Denmark making it to this list for the first time since a 1994 rockfall at Møns Klint killed one person, which is also the only other fatality we know of in DK. The 2024 entry is from a truely tragic incident where two kids got buried by a collapsing soft sediment coastal cliff only 5-10 m tall.
