ALASKA VOLCANO OBSERVATORY INFORMATION STATEMENT
U.S. Geological Survey
Wednesday, February 7, 2024, 10:42 AM AKST (Wednesday, February 7, 2024, 19:42 UTC)
FISHER (VNUM #311350)
54°40'9" N 164°21'9" W, Summit Elevation 3648 ft (1112 m)
Current Volcano Alert Level: UNASSIGNED
Current Aviation Color Code: UNASSIGNED
The Alaska Volcano Observatory (AVO) has experienced the failure of seismic monitoring equipment at Fisher Volcano and the remaining instrumentation is insufficient to establish that the volcano is at a typical background level. It is not possible to repair this equipment until next summer's field season. As a result, AVO is unable to (1) assess whether this volcano may be building towards an eruption and (2) quickly confirm or dismiss reports of activity.
The Aviation Color Code and Volcano Alert Level are changed to UNASSIGNED/UNASSIGNED because this volcano is no longer seismically monitored at adequate levels. As at other volcanoes without real-time seismic networks, AVO will continue to use satellite data, regional seismic, infrasound, and lightning networks, and reports from pilots and ground observers to detect signs of eruptive activity.
WESTDAHL (VNUM #311340)
54°31'2" N 164°38'51" W, Summit Elevation 5118 ft (1560 m)
