The largest landslide in modern U.S. history (in terms of volume) was most likely one that occurred in 2013 in Bingham Canyon outside of Salt Lake City, Utah. These mass wasting events can be very sudden, often slow and can move into larger movements of landslides. One of the main triggers of mass wasting on the island is the high-intensity rainfall that is associated with tropical atmospheric systems. 30 December 2020 Gjerdrum, Norway 2020 Gjerdrum landslide: 60.064612° N 11.036005° E 1.4–2.1 million cubic m.
