The Great Alskan Earthquake

On March 27, 1964, at 5:36 p.m. ADT (03:36 3/28 UTC) a great earthquake of magnitude 9.2 (moment magnitude) occurred in Prince William Sound region of Alaska. The northwestward motion of the Pacific plate at about 5 to 7 cm per year causes the crust of southern Alaska to be compressed and warped, with some areas along the coast being depressed and other areas inland being uplifted. The epicenter was about 10 km east of the mouth of College Fiord, approximately 90 km west of Valdez and 120 km east of Anchorage. The focus occurred at a depth of approximately 15.5 mi (25 km). The number of deaths from the earthquake totalled 131; 115 in Alaska and 16 in Oregon and California. Major structural damage occurred in many of the major cities in Alaska. The damage totaled 300-400 million dollars in 1964 dollars, ($2.3 billion in 2013 dollars). After the 1964 mega thrust earthquake, three-quarters of the Aleutian subduction zone ruptured in a span of eight years. The subduction zone is 2,100 miles (3,300 kilometers) long.
