ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Tuesday, January 30, 2024, 10:30 AM AKST (Tuesday, January 30, 2024, 19:30 UTC)
GREAT SITKIN (VNUM #311120)
52°4'35" N 176°6'39" W, Summit Elevation 5709 ft (1740 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Slow eruption of lava in the summit crater of Great Sitkin Volcano continues.
Infrequent, small volcanic earthquakes were detected over the past day. No activity was observed in mostly cloudy satellite or web camera imagery.
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.
SHISHALDIN (VNUM #311360)
54°45'19" N 163°58'16" W, Summit Elevation 9373 ft (2857 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Low-level unrest continues at Shishaldin Volcano in the form of small repeating volcanic earthquakes. No explosive activity was detected in infrasound data. Minor steaming from the summit was observed in clear webcam views 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. These mo
KANAGA (VNUM #311110)
51°55'27" N 177°9'44" W, Summit Elevation 4288 ft (1307 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Infrequent, small volcanic earthquakes were detected over the past day. Satellite and webcam views were cloudy over the last day.
A steam-driven explosion occurred at Kanaga on December 18, and seismic activity at the volcano has been above background. This unrest may mean that the likelihood for ash-producing explosive 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.
