Bogoslof Island is an important breeding ground for marine mammals and seabirds making it the perfect place to monitor how life responds to volcanic destruction.

The island is tiny. But it’s hard to say how tiny because the shape and size of the island are changing almost constantly since the eruptions started December 16. While recent eruptions have added new land, Chris Waythomas of the U.S. Geological Survey says on the whole, the roughly mile-long island has shrunk.

Eruptions at a volcano in the Eastern Aleutian Islands are thought to have begun earlier than previously thought.

According to a retrospective analysis, the Alaska Volcano Observatory now thinks Bogoslof volcano first erupted on December 16.

So far, the observatory believes there have been eight eruptions this month and there could be more. Previous eruptions have lasted weeks.

Seismic unrest continues at Bogoslof volcano. Scientists are watching the eruption around the clock -- even though monitoring stations are far from the site.

A volcano in the eastern Aleutians has been erupting for the past week. Bogoslof volcano is an uninhabited island 60 miles northwest of Unalaska. It’s part of the Alaska Maritime Wildlife Refuge, which is based hundreds of miles away in Homer. Steve Delehanty, the refuge’s manager, also lives in Homer. His reaction to hearing about the eruption was pure excitement.

After a quiet weekend, a volcano in the Eastern Aleutians is erupting again.


For the fourth time in less than a week, Bogoslof volcano has erupted prompting the Alaska Volcano Observatory (AVO) to issue its highest alert for air travel.


The observatory says today’s eruption threw ash 30,000 ft above the uninhabited island.
