Mount Pavlof

Mount Pavlof, a stratovolcano in the Aleutian Range on the Alaska Peninsula, has been one of the most active volcanoes in the United States in recent decades and is closely watched for the danger its ash poses to aviation. Confusion with nearby Pavlof Sister affected some early eruption records, but since 1980 Pavlof has erupted many times, including notable activity in 2007, 2013, 2014, 2016, and 2021–2022. The 2016 eruption gave only about 25 minutes of warning before sending ash to 37,000 feet and dropping tephra on Nelson Lagoon. Though not erupting in October 2024, it remained a high future threat.
