The Pavlof Volcano, which is about 600 miles southwest of Anchorage on the Aleutian Islands, erupted at 4:18 p.m. local time on Sunday, March 27th. The eruption sent ash 20,000 feet up in the air and prompted flight warnings according to authorities. Ash was seen generally moving north-to-northeast on infrared satellite imagery both immediately after the eruption (below) and earlier today (above). Seismic activity was also reported after the quake. A volcano alert warning remained in effect early Monday morning and the aviation warning color code remains red, its highest level.
The volcano last erupted in November 2014. The (USGS) agency says the volcano, which is about 4.4 miles in diameter, has had 40 known eruptions and “is one of the most consistently active volcanoes in the Aleutian arc.” A previous eruption in 2013 sent ash plumes rising 27,000 feet. Other eruptions have generated ash plumes as high as 49,000 feet. The community closest to the volcano is Cold Bay, which is about 37 miles southwest of it.
