Geologist. Landslides in Greenland and Denmark. And landslide tsunamis!

It does have these weird waves comming out the basal surface of rupture where it meets the water as the landslide body moves. I always wondered what that is? but not enough for a new Science paper i guess...

I guess with the right basin geometry.... But probably not for nine days:)

One hour(ish) out of cph - And to top the K-Pg boundery up there are plenty af landslides to study here!

A lot of that day was me saying: "take my word for it - this is a giant landslide - i've mapped it in the LiDAR model"

Dan is standing on the scarp of a giant roational landslide (900 by 400 m, in 40 m topography) in image 2. If he was stading there for ten years his legs would be a meter apart! The struggle is real....

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...

🌊 Our paper on the 2nd highest wave ever recorded – 481 m – is out in Science! A massive landslide-tsunami in Tracy Arm, Alaska, preconditioned by climate change. A genuine near-miss for cruise ship passengers. 🔗 doi.org/10.1126/scie... Thanks for leading this @watershedlab.bsky.social

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!

Recipe for disaster for sure. Add to that glacial debutressing from thinning glaciers (think Tracy Arm August 2025).

I actually have a proposal to build this in 2 by 1 m for large scale outdoor demos. I actually think it could get hazardous at that size when the toe thrusts forward

Yup - exactly what happened in the Karrat 2017 landslide: (presumable) permafrost degradation weakening the slope -> giant wave->inundating local village -> four people -> died village (still) evacuated And it is not the only case ve already hae. Now add ongoing climate change

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.

Also: I genuinely think landslides might be the geological process with the biggest direct footprint in popular music. Mayeb there is real science to be done here? If you’re in cultural studies/anthro/sociology and want to nerd out about this, let’s talk🤓

At #NWGM2026 conference, @ksvenenvig.bsky.social showed me a 3D-printed map of a #landslide in flattish Denmark and if this isn’t a great example of the power of lighting angles on DEMs, I don’t know what is. 🧪⚒️

Well actually 🤓 Its active landslides (the presentation). movement is triggered by coastal erosion and elevated water table but it is glaciotectinic structural inheritance that decides where they occur and why they are so big. But you are on the nose with the 3d printed (giant rellict) landslide
