The earthquake was recorded at 1:48 a.m. local time Saturday. The USGS National Earthquake Information Center in Golden, Colo., says it was most strongly felt in the Valdez area.
The quake was centered about 100 miles east-northeast of Anchorage and 25 miles south of Nelchina. It was about 20 miles deep.
