Perryville, Alaska (AP) - The Alaska Earthquake Center says a moderate earthquake struck Monday in the same region where a magnitude 7.8 earthquake occurred last week.
The center says Monday's quake, with a preliminary magnitude of 5.5, was an aftershock. It says the quake was lightly felt in King Cove, about 80 miles away.
The King Cove Department of Public Safety sent a notice to residents stating that continued aftershocks were expected.
Last week's quake was centered in waters 65 miles south-southeast of the tiny community of Perryville.
It generated tsunami warnings that later were canceled.
