The remote area of the western Aleutian Chain was the recipient of a 5.7 magnitude earthquake in the early morning hours on Sunday

Because of the relative remoteness of the arrea, there was no reports of damage or injuries.

The early morning event occurred at 4:48 am at the epicenter. It took place at a depth of 27.3 miles beneath the seafloor about 16 miles to the South-Southwest of Tanaga volcano in an uninhabited portion of the western reaches of the Aleutian Island group to the west of Adak.

The shaker took place in the area where the Pacific Plate subducts under the North American Plate. It is exactly this subduction that formed thedeep Aleutian Trench and the accompanying Aeutian Islands. The region is home to thrtust faulting that can result in devastating earthquakes.

The area has hosted at ;east twelve very large earrthquakes over 7.5 magnitude since 1900.

No Tsunami was generated as a result of the quake.
