Unrest continues at Pavlof. Seismicity has decreased since yesterday. No signs of continuous tremor . Occasional discrete events continue. This morning, web camera images from a remote site located at Black Hills (20 miles or 35 km NNE of Pavlof) show minor steam emissions with no evidence of ash. Satellite observations are mostly obscured by high clouds.

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.
