One Aleutian volcano has erupted again, and another is showing signs of life.

Bogoslof Volcano erupted early Tuesday morning, continuing a series of explosions that date back to mid-December.

The Alaska Volcano Observatory (AVO) warned a trace amount of ash could fall on Unalaska, 60 miles to the east, but there have been no reports of it reaching the island.

Meanwhile, the AVO has increased the alert level for Takawangha Volcano, 60 miles west of Adak.

The National Weather Service has issued a Blizzard Warning for the Unalaska area from 6AM to 4PM on Sunday, 01/22/2017.   There is expected to be winds from the East of 45 to 60MPH with gusts to 80 MPH.  Additionally, snow accumulation of 3 to 6 inches is expected along with visibility of one quarter mile or less.  Snowfall combined with strong winds and blowing snow will produce white-out conditions.  Please secure loose objects around your residence and businesses.  Motorists should exercise caution. Alaska statute requires headlights to be illuminated when visibility is limited.

Bogoslof Volcano erupted again Wednesday, spewing a cloud of ash that was visible from Unalaska.

The volcano blew around 1:20 p.m., sending ash at least 31,000 feet into the air and prompting the Alaska Volcano Observatory to raise its alert level to red.

That’s the highest status, indicating a hazardous eruption is underway or imminent.

New photos show the dramatic effect of volcanic explosions on Bogoslof Island. The Eastern Aleutian island is home to a volcano that has been erupting since mid-December. Now, the tiny island is even smaller and it’s shaped like a hook.

Chris Waythomas, of the U.S. Geological Survey, says the photos also show ash on the island.

“There’s ash draping over everything,” said Waythomas. “There’s a layer of fine muddy-looking ash covering what was a partially vegetated island.”

Two hours after lowering the aviation code for an Eastern Aleutian volcano, it’s back at the highest alert level.

The reasoning? According to the Alaska Volcano Observatory, there was a significant explosion at Bogoslof volcano Thursday afternoon.
