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.

Shishaldin Volcano had an eruption Friday morning that produced an ash cloud approximately 24,000 feet and volcanic lightning.

Matt Haney, a geophysicist with the Alaska Volcano Observatory, said the volcano  – located about 58 miles southwest of Cold Bay – has been active since July. 

Shishaldin Volcano, located about 58 miles southwest of Cold Bay, had a low-level eruption over the weekend.

According to the Alaska Volcano Observatory, lava effusion has paused, but the surface temperature remains elevated.

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.
