The Alta landslide occurred on 3 June 2020 in the locality of Kråkneset, Talvik, in the municipality of Alta in northern Norway. 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]
