The strong continuous seismic activity that started abruptly last night at about 10:40 UTC 12/22 (01:40 AKST) ended at 16:40 UTC (07:40 AKST) this morning. There is no evidence that an eruption cloud was produced or that ash emission occurred.
AVO has no ground-based volcano monitoring equipment on Bogoslof volcano. We will monitor satellite images and data from distant seismic and infrasound instruments 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.
