ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Thursday, January 26, 2017, 3:18 AM AKST (Thursday, January 26, 2017, 12:18 UTC)
53°55'38" N 168°2'4" W,
Summit Elevation 492 ft (150 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
An hour-long increase in seismicity that began at about 01:34 AKST (10:24 UTC) has subsided. There has been no evidence of eruptive activity observed in satellite, lightning or infrasound data. Bogoslof remains at an elevated state of unrest and explosive activity is possible at any time without detectable precursory activity. This will be the last report on this most recent episode of activity.
The Aviation Color Code remains at ORANGE and the Alert Level remains at WATCH.
AVO has no ground-based volcano monitoring equipment on Bogoslof volcano. We continue to monitor satellite images, data from distant seismic and infrasound instruments, and information from the Worldwide Lightning Location Network for indications of significant activity.
OTHER ALASKA VOLCANOES
Other Alaska volcanoes show no signs of significant unrest: http://www.avo.alaska.edu/activity/
AVO scientists conduct daily checks of earthquake activity at all seismically-monitored volcanoes, examine web camera and satellite images for evidence of airborne ash and elevated surface temperatures, and consult other monitoring data as needed.
