Sometimes geomorphology and archaeology intersect in fascinating ways! Today in Vejle Ådal, Denmark, I joined archaeologist Tobias Torfing of VejleMuseerne. His Iron Age trenches give us a window underground as we investigate a possible ~14,000-year-old postglacial landslide.

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.
