Update, 1:30pm: King Cove is reporting light ashfall in town

Original story: Pavlof Volcano, on the Alaska Peninsula, spewed a 26,000-foot ash cloud early Tuesday morning. That’s the largest plume the volcano has put up since it started erupting in early May.At that elevation, it isn't interfering with international air traffic passing over the region, but it is proving problematic for regional air service.

According to the terminal agent in Cold Bay, PenAir turned around a cargo run to the community this morning, and canceled its passenger flight as well. Unalaska's passenger flights are running as scheduled, according to station manager Lowell Crezee, and shouldn't be impacted by the eruption.

PenAir's main office couldn’t be reached for information about flights to other communities.

The National Weather Service has issued an ash advisory for the Alaska Peninsula, but so far, there have been no reports of ashfall. And according to Alaska Volcano Observatory geophysicist Dave Schneider, there likely won’t be.

“The direction it’s heading, it’s not really heading toward any of the villages," Schneider says. "It’s a little bit east of Nelson Lagoon, and to the west of Port Heiden. So it’s in a place where there’s not really a lot of people.”

Schneider says the volcano is still showing signs of increased activity, and could put up more ash plumes at any time.

Pavlof is the most active volcano in Alaska, and has previously erupted for weeks, or even months, at a time, although it typically cycles through periods of intense activity, like the current one.
