A landslide into Lituya Bay, Alaska, in 1958 sent water over the ridge

An earthquake shook loose a huge rockfall at the head of Lituya Bay, and the water it displaced surged up the opposite slope, stripping trees to a height of 524 metres. Three fishing boats were in the bay; one rode over the wave and survived. It is a megatsunami, caused by displacement rather than by a tectonic sea-floor shift.
