AVO

Seismic activity at Shishaldin Volcano is back down after an eruption yesterday caused flights to be cancelled out of Cold Bay – about 58 miles to the northeast.

The Alaska Volcano Observatory (AVO) lowered the Aviation Color Code to "orange" and Alert Level to "watch." 

The volcano has been active since July, and has had two ash eruptions in the past week.

Ash eruption at Shishaldin Volcano continues and has intensified as shown in satellite and lightning data. The Aviation Color Code has increased to "red" and Alert Level has increased to "warning."

Hans Schwaiger, a geophysicist with the Alaska Volcano Observatory, said the volcano - 58 miles southwest of Cold Bay – began erupting again this morning, and had sent an ash cloud 27,000 feet that is drifting to the east-northeast, as of 1 p.m.

After showing signs of restlessness, Pavlof Volcano is back at a normal alert level.

The Alaska Volcano Observatory issued an "advisory" for Pavlof last month, following small explosions at its summit 36 miles northeast of Cold Bay. Since then, there have been no further signs of unrest, and scientists downgraded the volcano to "normal" last week.

The alert level for Bogoslof Volcano has been downgraded to “normal” after more than three months of inactivity.

The Alaska Volcano Observatory made the announcement Wednesday, although scientists say remote monitoring makes it difficult to determine if the eruption is really over.

While Bogoslof exploded more than 40 times in the last year, the AVO says all signs now point to another period of quiet.
