ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Saturday, February 10, 2024, 11:14 AM AKST (Saturday, February 10, 2024, 20:14 UTC)
Slow eruption of lava in the summit crater of Great Sitkin Volcano likely continues. The volcano was seismically quiet over the past day. Clouds have obscured satellite and web camera 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; clouds have obscured satellite and web camera views of the volcano.
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.
Low-level unrest, characterized by small, occasional volcanic earthquakes, continues at Shishaldin Volcano. Clouds have obscured satellite and web camera views of the volcano over the past day.
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.
