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. [1] This substrate is thought to have turned into quick clay leading to landslide. [1]
The landslide was filmed by a resident. There were no casualties, but several homes and cabins were lost, and a dog was rescued from the sea. [2] [3] [4]
Residents had alerted the authorities about a small landslide five days before the larger event happened. [5] Three days after the initial landslide, a second landslide destroyed part of the coastal highway. [6]
