After covering a large portion of Iceland with ash in late May 2011, Grímsvötn Volcano left behind a small lake filled with meltwater and a hole in the Vatnajökull Glacier.
The thick brown plume of ash, steam and volcanic gas rising from Anak Krakatau in this true-color image from November 17, 2010, is a common sight at the volcano
Acquired February 11, 2010, this true-color image shows water discoloration immediately west of the underwater summit of Fukutoku-Okanoba. Clouds overhead might result from vapor emissions, but might be unrelated to volcanic activity.
