1964: Alaska's Good Friday Earthquake

On March 27, 1964, a megathrust earthquake struck Alaska, about 15 miles below Prince William Sound, halfway between Anchorage and Valdez. The quake had a moment magnitude of 9.2, making it the second most powerful earthquake ever recorded. The initial quake and subsequent underwater landslides caused numerous tsunamis, which inflicted heavy damage on the coastal towns of Valdez, Whittier, Seward, and Kodiak. Alaska's biggest city, Anchorage, suffered numerous landslides, destroying city blocks and neighborhoods. An estimated 139 people were killed, most by tsunamis -- including 16 deaths on Oregon and California shorelines. The old town site of Valdez was abandoned, with reconstruction taking place on stable ground nearby. This is the fourth of five entries focusing on events of the year 1964 this week (and next Monday). Monday's entry will feature images of the New York World's Fair.
