1964 Great Alaska earthquake

The rupture ran along a fault between the Pacific and North American plates about 14 miles beneath the seafloor of Prince William Sound, on the afternoon of 27 March local time, and set off a Pacific-wide tsunami. Submarine and coastal landslides accompanied the shock, and the catalogue records the earthquake and the slides together as the source of the waves. Kodiak was among the Alaska communities hit, with much of the town destroyed by a tsunami.
