Pavlof (United States) - Report for 17 November-23 November 2021

AVO reported that the eruption at Pavlof continued during 14-23 November and was focused at a vent on the upper NE flank.
Seismicity remained elevated and signals were periodically recorded that were likely explosions.
Lava fountaining began on 14 November and had built a small, unstable cone.
Hot debris from the cone traveled a few hundred meters down the flanks, melting snow and ice that resulted in narrow lahars which traveled several kilometers down the flanks.
Elevated surface temperatures were observed in satellite data at least through 23 November, suggesting that the lava fountaining continued.
The Volcano Alert Level remained at Watch and the Aviation Color Code remained at Orange.
