A fissure vent in the Fimmvörðuháls region of southern Iceland, caused by the 2010 eruption of Eyjafjallajökull. The eruption opened the 0.5 km (0.31 mi) long fissure on March 20, 2010, and a second eruption a week later opened a second fissure, as well as two craters, which were named Móði and Magni, after the sons of Thor, the Norse god of thunder.Photo: Henrik Thorburn
