Askja represents a volcanic system with nested calderas north of Vatnajökull. The eruption of 1875 resulted in the formation a huge caldera which was later filled by lake Öskjuvatn, 11 square kilometres large and more than 200 m deep. This small island in Öskjuvatn was created by a phreatomagmatic eruption in 1926.
