Mount Pavlof or Pavlof Volcano is a stratovolcano of the Aleutian Range on the Alaska Peninsula. It has been one of the most active volcanoes in the United States since 1980, with eruptions recorded in 1980, 1981, 1983, 1986–1988, 1996–1997, 2007, 2013, twice in 2014, 2016, and again in 2021-2022.[2][3][4][5][6] It is not currently erupting (as of October 15, 2024).[6] The most common lava type here is basaltic andesite and the 2013-2014 lavas contained approximately 53 wt.% SiO2.[7] The volcano is monitored by the Alaska Volcano Observatory- a joint program of the United States Geological Survey (USGS), the Geophysical Institute of the University of Alaska Fairbanks (UAFGI), and the State of Alaska Division of Geological and Geophysical Surveys (ADGGS). With a threat score of 95,[8] the threat from future eruptions is considered to be high; much of this threat comes from the possibility of disruption of nearby air routes by large releases of ash.[8] The mountain shares a name with the nearby Pavlof Sister, which is thought to have last erupted from 1762 to 1786, although this period of activity is sometimes attributed to Pavlof volcano instead.[9]
