Caption:Digital Globe satellite image of Pavlof Volcano in eruption, March 28 21:47 UTC. The dark streaks in the image are volcanic debris-flow deposits (lahars) generated by the interaction of hot eruptive material and snow and ice on the volcano. A robust ash plume obscures the north side of the volcano. This is the first time since the 1986-88 eruptive period that lahars have formed on both the north and south sides of the volcano.

Caption: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.
