ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Monday, February 12, 2024, 12:19 PM AKST (Monday, February 12, 2024, 21:19 UTC)
Low-level unrest continues at Shishaldin Volcano with occasional small volcanic earthquakes. Very minor ash emissions were observed at the summit in one webcam image over the past 24 hours.
No eruptive activity has been observed since November 2023.
Local seismic and infrasound sensors, web cameras, and a geodetic network are used to monitor Shishaldin Volcano. In addition to the local monitoring network, AVO uses nearby geophysical networks, regional infrasound and lighting data, and satellite images to detect eruptions.
Slow eruption of lava in the summit crater of Great Sitkin Volcano likely continues. Occasional small earthquakes were recorded over the past day. No activity was observed in cloudy satellite and webcam images.
The current lava flow began erupting in July 2021. No explosive events have occurred since a single event in May 2021.
Local seismic and infrasound sensors and web cameras are used to monitor Great Sitkin along with regional infrasound and lightning networks and satellite data.
Kanaga Volcano was seismically quiet over the past day. No activity was observed in cloudy satellite and webcam images over the last day.
A steam-driven explosion occurred at Kanaga on December 18, 2023 and since then, seismic activity at the volcano has been above background. This unrest may mean that the likelihood of explosive ash-producing activity has increased.
Local seismic and infrasound sensors and web cameras are used to monitor Kanaga. AVO also uses regional infrasound and lightning networks as well as satellite data.
