Unmatched in U.S. History
The massive magnitude-9.2 Alaska earthquake changed the world by proving plate tectonics works. Since the quake struck on March 27, 1964, there has never been another earthquake as powerful. The remarkably low death toll of 131 people belies the quake's incredible effects on the Earth.
Uplifted seafloor at Cape Cleare, Montague Island, Prince William Sound, the flat rocky surface with the white coating is about a quarter of a mile (400 meters) wide. It was below sea level before the earthquake.
The village of Portage was abandoned after it sunk 6 feet (1.8 m) in the earthquake.
Underwater landslides triggered deadly tsunamis before the shaking stopped. Here, trees up to 101 feet (30 m) above sea level were splintered by the tsunami generated by an underwater landslide in Port Valdez, Prince William Sound.

Oil tanks failed and caught fire at many coastal towns and villages, including Valdez, seen here. The fire burned for two weeks.
One of the iconic images of the 1964 earthquake is the collapse of Fourth Avenue near C Street in Anchorage from a landslide.
