Bogoslof Island is a small, remote, volcanic island in the Bering Sea, approximately 60 nautical miles west of Dutch Harbor, Alaska (Fig. Despite its small size, Bogoslof Island teems with wildlife and is home to seabird, Steller sea lion, and northern fur seal breeding colonies. Northern fur. Dec 12, 2016 Bogoslof Island is the largest of a cluster of small, low-lying islands comprising the emergent summit of a large submarine stratovolcano. This stratovolcano rises about 6000 ft (1800 m) from the Bering Sea floor, but is only about 300 ft (100 m) above sea level at its highest point. Bogoslof volcano is unusual in its location.

Alaska's Bogoslof Volcano erupted Sunday, sending a plume of ash at least 35,000 feet into the air and temporarily triggering the highest aviation alert, scientists say.
The Bogoslof Volcano in the Aleutian Islands erupted at 2:16 p.m. Sunday, according to the Alaska Volcano Observatory. The eruption lasted 55 minutes.
No further ash emissions have occurred at Bogoslof Volcano since the explosion, and seismic activity remains low, according to the observatory.
“We are therefore lowering the Aviation Color Code to ORANGE and the Alert Level to WATCH,” the agency said in a statement. “Additional ash-producing eruptions could occur at any time, however, with no detectable precursors.”
The clouds of ash from erupting volcanoes are a threat to jet engines. Airliners operating between North America and Asia fly in Bogoslof’s path.
Volcano eruptions have wreaked havoc on air travel in the past, not to mention caused significant environmental impact. In 2010, the eruption of Iceland's Eyjafjallajökull Volcano led to the cancellation of tens of thousands of flights in Europe.

ANCHORAGE, Alaska -- A volcano is erupting again in Alaska’s Aleutian Islands.
The Alaska Volcano Observatory says a Coast Guard vessel crew was in the area of the Bogoslof volcano Friday morning and witnessed an ash plume from the eruption that lasted about one hour.
Volcanologist Robert McGimsey says the plume was estimated at below 30,000 feet.
He says Unalaska Island about 61 miles from the volcano is the closest populated area but that that winds were blowing any ash away from inhabited areas.
The eruption prompted the observatory to issue its highest alert level for aviation again after the volcano’s eruptions earlier this week also prompted the highest alert level.
Federal Aviation Administration spokesman Allen Kenitzer says airlines were rerouting flights around the plume.
He says there were no reported delays.
