Annotated photo of Bogoslof Island showing effects of eruption

Detailed Description

Annotated photograph of Bogoslof Island showing the cumulative effects of 2016-17 eruptive activity. A layer of fine muddy appearing ash drapes most of the landscape and covers pre-existing vegetation. The dashed line indicates the area excavated by explosive eruptive activity so far. A prominent zone of upwelling is probably the surface expression of a shallow submarine vent. Photograph taken by Dan Leary, Maritime Helicopters, January 10, 2017.
