Another volcano rumbling in Alaska

ANCHORAGE, Alaska – Another volcano in Alaska is heating up, with seismic instruments signaling a possible eruption, scientists said Monday.

Tremors were detected at Pavlof Volcano, 625 miles southwest of Anchorage, according to the Alaska Volcano Observatory. Satellite imagery showed the mountain was “very, very hot,” said John Power, the U.S. Geological Survey scientist in charge at the observatory.

The aviation alert level for Pavlof was raised from “yellow” to “orange.” A major ash emission could threaten international flights.

Pavlof is 37 miles from the tiny community of Cold Bay, which was notified of the new activity that began about 8 a.m. Monday.

The volcano last erupted in 2007, but residents there said that eruption had no impact on Cold Bay, likely because the winds blew away any ash fall.

Pavlof is the second Alaska volcano to rumble this month.

Cleveland Volcano, on an uninhabited island in the Aleutian Islands, experienced a low-level eruption in early May.
