Monday, Oct. 5, 2015, a magnitude 5.7 earthquake struck north west of Amatignak Island in Alaska. The quake’s epicenter was located between the Bering Sea and the North Pacific Ocean. The island is uninhabited, therefore, if seismic sea waves overcome its topical surface it will not threaten human life. Presently, no tsunami warnings have been issued.
According to scientific studies on the area, the sea where Amatignak Island is positioned forms part of the Aleutian Arc in the Northern Pacific Ocean. Earthquakes frequently visit this area where the Pacific plate withdraws underneath the North America plate. Quake experts say that the general region exhibits a history of powerful shakes called megathrust earthquakes because they occur where two plates converge.
This most recent quake is one in a series of large temblors, 5.0 and above, to strike land and sea since the Sept., 27, Blood Moon event.
Some of the information provided in this report has been taken from the USGS Earthquake Notification Service, which maintains seismotectonic data of Alaska.
There have been at least 7 quakes in the area over the last 30 days. Today’s 5.7 was the largest to have occurred in the region since the massive 7.9 shake hit on June 23, 2014.
