1964 Great Alaska Earthquake and Tsunamis

At 5:36 pm (Alaska time) on March 27, 1964, without warning, the largest recorded earthquake in U.S. history occurred in Alaska’s Prince William Sound. Valdez, Anchorage, and many villages along the Alaska Coast were significantly damaged or destroyed by the magnitude 9.2 earthquake and the tsunamis that followed. Over 130 people died in Alaska, Oregon, and California. Damage from the tsunamis alone, which also impacted the west coasts of the United States and Canada and Hawaii, was estimated at almost $1 billion (2015 dollars).
