Increased seismic activity has been detected at the volcano and its alert status was raised to Yellow. The Alaska Volcano Observatory reports:"The rate of long-period earthquakes has increased at Pavlof Volcano since approximately 12:45 am AKST (09:45 UTC) on January 14. No eruptive activity or emissions from the summit have been observed including in clear webcam images from this morning. The earthquake activity represents an increase from background levels, therefore the Alaska Volcano Observatory is raising the Aviation Color Code and Alert Level to YELLOW/ADVISORY. This type of earthquake activity in the past has preceded eruptions, but also has ended without an eruption occurring. We will continue to closely monitor the volcano for signs of increased activity, as eruptions at Pavlof Volcano often occur suddenly with little or no warning.The last eruption at Pavlof Volcano occurred in 2021 and 2022, and consisted of small lava flows and low-level explosions primarily from a vent on the upper southeast flank. Larger ash-producing eruptions last occurred at Pavlof in 2013, 2014, and 2016 from a crater on the upper north flank."
