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 🤘🤯

Podcast: Forskeres minutiøse detektivarbejde har afsløret, at et fjeldskred sidste år udløste verdenshistoriens næststørste tsunami på 481 meter i en billedskøn fjord, som tiltrækker eventyrlystne turister. Lyt og få en tsunami i øret @ksvenenvig.bsky.social politiken.dk/del/GuiltCAH...

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...

Et forskerhold med dansk deltagelse har løst mysteriet om, hvorfor vores klode rystede 36 timer i træk. Læs og lyt med her, hvordan det både skræmmende og fascinerende naturfænomen opstod, og hvorfor det vil ske med større frekvens i fremtiden @ksvenenvig.bsky.social politiken.dk/del/tvYowYAH...

This long-lasting, globally observable seiche is only the second time such a signal has been observed, after the Dickson Fjord event in 2023, described in this study by @ksvenenvig.bsky.social and others www.science.org/doi/10.1126/...

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...

🌊 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!

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.

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. 🧪⚒️

and i was todays yers old when i found out (most) n-americans eat with the knife and fork opposite! 🍴=correct. For god's sake @watershedlab.bsky.social even the emojis agree with me on this 🍽️

Look what arrived: Just bought two original hand-painted prints from Møns and Stevns Cliffs, Denmark, from 1851. These are photorealistic, made in collaboration by some of the best artists and scientists of the era.

Just add water: 3D printed rotational landslide. Working on improving these models so the print files can be shared for outreach and teaching.

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).

That tsunamigenic landslide is impressive.

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. 🧵

I denne #GEUS rapport kan du få indblik i den geologiske faglighed, som kvalificerer spørgsmål fra #kystdirektoratet vedr. skredaktivitetssagen ført an af @ksvenenvig.bsky.social og @mariekeiding.bsky.social www.geus.dk/om-geus/nyhe...

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 🏠 📷 Pomona

Seeing Blatten buried again and again, from every angle... Properly staggering! 😮😱

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.

...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. www.science.org/doi/10.1126/... 10/

AGU has joined a lawsuit challenging the firing of probationary employees at federal agencies. These actions weaken science, harm public health & the environment, and threaten national security. 🧵 #StandWithScience

A 7 km² Landslide in Denmark?! Take a look at this massive beauty! Our peaceful (some might say “boring”) Danish landscape near Vejle hides giant secrets: colossal landslides from thousands of years ago. Completely unknown to scientist and locals alike.
