Pavlof Volcano in eruption, March 28, 2016. The annotations show several of the processes that were occurring during the eruption including the formation of hot granular flows of rock material, the formation of lahar deposits, white steam plumes associated with the interaction of hot eruptive material and snow and ice, and the vertical ash column and drifting ash cloud. Pavlof sits just outside of Emmons Lake caldera, one of the largest caldera structures in the Aleutian arc. Also shown are several of the young post-caldera volcanoes inside the caldera. View is toward the north east.
