Alta landslide

The Alta landslide occurred on 3 June 2020 in Alta Municipality in Finnmark county, Norway. The landslide took place in Kråkneset, a small village about 6 kilometres (3.7 mi) southeast of the larger village of Talvik. The landslide took place on the side of a mountain and down into the Altafjorden. The landslide developed on a marine clay substrate that had originally formed in the early Holocene epoch when the area was under sea level. This substrate is thought to have turned into quick clay leading to landslide.
