Major earthquake hits off Alaska's Aleutian Islands, sets off tsunami

JUNEAU, Alaska: A magnitude 7.9 earthquake struck deep under the ocean floor near Alaska's Aleutian Islands, triggering shaking felt over vast distances and setting off a small tsunami, the National Tsunami Warning Center said.

A tsunami warning, later downgraded to an advisory, prompted the evacuation of about 200 residents of the town of Adak to higher ground, city manager Layton Lockett said.
