1964 Great Alaska Earthquake

The 1964 Great Alaska earthquake (also known as Good Friday earthquake) occurred at 5:36 P.M. (local time, 3:36 UTC) on Good Friday, March 27 in the Prince William Sound region of Alaska. It lasted approximately 4.5 minutes and is the most powerful recorded earthquake in U.S. history.

The earthquake triggered 27-foot (8.2 meters) tsunami which destroyed the village of Chenega, killing 23 of the 68 people who lived there. Survivors out-ran the wave, climbing to high ground. It also caused a massive underwater landslide. Port Valdez city harbor and docks were collapsed, 30 people perished.

A total of 139 people are believed to have died: 15 as a result of the earthquake itself, 106 from the subsequent tsunami in Alaska, 5 from the tsunami in Oregon, and 13 from the tsunami in California.
