Pavlov Volcano, which has been erupting all week, continues to do so. As of Sunday, its plume has risen above the 20,000 foot level considered the threshold where it becomes a threat to trans-continental commercial aircraft.

The plume, as of yesterday, has been periodically reaching heights of 22,000 feet as it continues to spew ash and gas.

It was reported this weekend that a light layer of ash had fallen in the community of Sand Point. Advisories for Sand Point and Nelson Lagoon were issued over the weekend, both of those advisories have now expired.

The ashfall from the erupting volcano is expected to continue to fall in minor and trace amounts to the southeast of the vicinity of the volcano. Ash is likely falling to the north, east and southeast flanks of the volcano and in Pavlov Bay.

Seismic activity remains elevated with a continuous volcanic tremor according to the Alaska Volcano Observatory.

Activity at the volcanic site, approximately 625 miles to the southwest of Anchorage, Alaska’s largest urban area, elevated on last Monday, but was not visually confirmed until Tuesday. Then, pilots reported spatter-fed lava advancing down the north flank of the volcano.

By Wednesday, residents of Cold Bay saw an incandescent golow coming from the volcano during the night. By Thursday, images of lava fountaining at the summit were taken.

Pavlov, one of the most frequently erupting volcanoes in the Aleutian arc last erupted in August of 2007 after laying quietly for 11-years.
