Possible plume and ash

Satellite image from 19th April 2015 on the EOSDIS website showed a clear view of Saunders Island and what appeared to be a plume rising from Mount Michael Volcano. As in most cases, the satellite image wasn't clear enough to determine whether or not it was an eruption plume.

On the Earth Explorer website, a satellite image of Saunders Island from the 20th April 2015 showed what was mostly a cloudy day but the southwest portion of the island was visible. It showed what appeared to be a cloud with some possible ash content immediately to the west-southwest of the summit area of Mount Michael drifting southwest bound.
