Earthquake in Alaska

Listen to this article

The U.S. Geological Survey has reported a severe earthquake struck southern Alaska, about 51 miles east Old Iliamna. The reported strength was a magnitude 7.1, at an intermediate depth of 76 miles.

The quake occurred at 1:30 a.m. local time, about 2:30 a.m. Pacific Time and could be felt in Anchorage, which is about 162 miles northeast of the epicenter.

The USGS doesn’t expect there will be any severe damage or injuries connected with this event. The National Weather Service said there shouldn’t be a tsunami from this quake because it occurred so deep.

Two smaller quakes struck afterwards, but authorities said there was little likelihood of any damage or injury from the quakes. The Alaska Earthquake Center at the University of Alaska-Fairbanks reported about 30 aftershocks have occurred since then.

Alaska has a high number of earthquakes due to its location near the Pacific:North America subduction zone plate boundary. The area just southeast of this latest quake had the second strongest earthquake in modern history on March 22, 1964, which was measured at M9.1.
