Communities along a 700-mile stretch of Alaska’s southern coast ordered their residents to higher ground after a powerful earthquake, but officials quickly downgraded and then canceled a tsunami warning in the area.

A major earthquake with a preliminary magnitude of 7.2 has triggered a tsunami warning for the southern Alaska peninsula.

A rare tsunami warning was issued for part of Alaska’s coast after a magnitude 7.3 earthquake struck near Sand Point in the Aleutian Islands. A small tsunami wave was measured at Sand Point, Alaska.
