The 1964 Alaska earthquake tsunami devastated which California city?

The 1964 Alaska earthquake tsunami devastated Crescent City, California, after the magnitude 9.2 earthquake struck Prince William Sound on March 27. The resulting trans-Pacific tsunami travelled south along the North American coast and hit Crescent City with exceptional force.

Crescent City’s underwater geography funnels and focuses tsunami energy, making the harbor particularly vulnerable. The 1964 waves destroyed about 30 city blocks, including much of the waterfront business district. Ten people died in Crescent City, and the tsunami caused most of the California deaths attributed to the Alaska earthquake.

The event was not a single simple wave. The earthquake generated a major tectonic tsunami, while underwater and coastal landslides produced additional local waves. Alaska suffered the greatest overall destruction, but Crescent City became one of the best-known American locations associated with the disaster. Santa Cruz, Los Angeles, and San Francisco experienced Pacific tsunami effects at various times, but Crescent City was the California city devastated in 1964.
