A strong earthquake has struck in a remote area of Alaska's Aleutian Islands, but officials say there have been no reports of any damage.
The Alaska Earthquake Center says the magnitude 5.9 temblor struck at 11:15 p.m. Sunday and was centered in the Bering Sea about 140 miles east of Adak or 1,100 miles southwest of Anchorage.
A series of quakes measuring between magnitude 5.2 and 4.2 struck in the same area over the next couple hours.
The center says there have been no reports of any damage.
