The Great Alaska Earthquake
At 5.36 in the evening of Good Friday, 27 March 1964, a magnitude 9.2 earthquake struck Prince William Sound in southern Alaska. It shook for about four and a half minutes and remains the most powerful earthquake recorded in US history, and the second most powerful measured anywhere.
Whole neighbourhoods of Anchorage slid away, the ground rose by as much as 25 metres in places, and tsunamis swept the coast as far as California. 131 people died. A US Geological Survey scientist, George Plafker, showed it had happened where one of the Earth’s plates slides beneath another, helping to prove the theory of plate tectonics.
