Eyjafjallajökull - hot and cold

by Adam Ciesielski, Karlsruhe Institute of Technology, Karlsruhe, Germany

Active volcano Eyjafjallajökull is covered by 80 square kilometres of glaciers. Quite often one can feel the warmth from the red igneous rocks that protrude from the ice cap.
The volcano is known for the eruption in April 2010, which released ash clouds so large that in some areas they turned daylight into darkness. Many flights in Europe were cancelled. A significant part of the glacier melted in a very short time, posing a flooding threat to the island's inhabitants.
