After covering a large portion of Iceland with ash in late May 2011, Grímsvötn Volcano in Iceland left behind a small lake filled with melt water and a hole in the Vatnajökull Glacier.

The below natural-color satellite image was acquired by the Advanced Land Imager (ALI) aboard Earth Observing-1 (EO-1) on June 11, 2011.

The lake covers much of the site of the eruption, with the possible exception of the crescent-shaped feature along the southern shore of the lake. This may be a tephra cone left behind by the eruption. Gray ash covers the ice of Vatnajökull Glacier near the vent. Further away, the ash layer itself is obscured by snow.

Grímsvötn erupted on 21 May 2011 and forced the closure of airspace over parts of northern Europe. The eruption occured just over one year on from an explosive eruption at the Eyjafjallajökull volcano in Iceland.
