A powerful 7.3-magnitude earthquake has triggered a tsunami warning along a 700-mile stretch of Alaska's southern coast, prompting communities to order residents to higher ground.
The tremor struck at 12:37 p.m. local time, just south of Sand Point, a community of approximately 580 people located on Popof Island in the Aleutian chain. While initial projections indicated the first waves would hit this area, the state's emergency management division reported no damage an hour after the quake.
