Cloudy Skies at Makushin volcano (C) U.S. Geological SurveyThe Alaskan Volcano Observatory (AVO) report that the small earthquakes which began on June 15 continues. These earthquakes are located southeast of the summit. No activity was observed in cloudy satellite and web camera imagery.
AVO mention that the earthquake sequence may be associated with volcanic unrest, but there have been no signs of deformation or surface activity noted in other monitoring data. Should an eruption occur, it would be likely to see additional signs of unrest prior to the onset. Also, the main hazard would likely be from airborne ash and ash fall.
