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.
