Adak

A magnitude 6.2 earthquake struck southeast of Adak early Friday, part of a continuing swarm with several quakes measuring 4.0 or higher since Wednesday.

A NOAA Ocean Exploration-led team has discovered what appears to be evidence of a large gas seep at a depth of nearly 1.4 miles (2,300 meters) along the Aleutian Trench. The discovery was found in data collected during the Seascape Alaska 1: Aleutians Deepwater Mapping expedition.

Three volcanoes are erupting across the Aleutian Range — Great Sitkin and Semisopochnoi in the Aleutian Islands and Pavlof Volcano on the Alaska Peninsula.

For the first time in more than 30 years, the Navy staged a joint training exercise on the far-western Aleutian island. Some are hoping it portends a permanent future in the region.

The vessel remained afloat as of Thursday morning, and images gathered by the U.S. Coast Guard showed it was still “alight with smoke emanating” from it.
