ANCHORAGE, Alaska (August 30, 2013)--A magnitude 7.0 earthquake struck Alaska's Aleutian Islands Friday morning, the U.S. Geological Survey said.
The USGS said the earthquake struck at around 8:25 a.m. Alaska time and was centered about 67 miles southwest of Adak, Alaska.
The Alaska Earthquake Information Center said in a statement that the quake was felt strongly in Adak and Atka, and shaking lasted as long as one minute.
There were no immediate reports of damage.
The earthquake didn't trigger a tsunami warning, but Michael Burgy with the West Coast and Alaska Tsunami Warning Center in Palmer, Alaska, says the center was monitoring for potential tsunamis caused by landslides, either on land or under water.
Atka is about 1,200 miles southwest of Anchorage.
