A strong earthquake struck late Friday evening on the Alaskan Peninsula.
The magnitude-6.2 temblor occurred at 9:50 p.m. local time Friday (1:50 a.m. Saturday EDT) 62 miles north-northeast of Chignik Lake, Alaska, the United States Geological Survey reported. The initial magnitude was listed at 6.4.
The epicenter is also 13 miles northeast of Aniakchak Crater, according to the Alaska Earthquake Center at the University of Alaska, Fairbanks.
As many as two large aftershocks occurred within 10 minutes of the initial quake, the Alaska center website showed.
Aniakchak Crater is part of the Aniakchak National Monument and Preserve, the site of a 3,500-year-old volcanic caldera.
The earthquakes at the caldera follow the eruption of Mount Pavlof on March 27.
