Mýrdalsjökull, Iceland

Mýrdalsjökull is a glacier in the south of Iceland. It is situated to the north of Vík í Mýrdal and to the east of the smaller glacier Eyjafjallajökull. The icecap of the glacier covers an active volcano called Katla. The caldera of the volcano has a diameter of 10 km and the volcano erupts usually every 40–80 years. As the last eruption took place in 1918, scientists are monitoring the volcano very carefully as they believe an eruption of Katla is on the cards, particularly after the eruption of Eyjafjallajökull began in April 2010.

Hekla, Iceland

Hekla is a stratovolcano located in the south of Iceland with a height of 1,491 metres. Hekla is one of Iceland's most active volcanoes; over 20 eruptions have occurred in and around the volcano since 874. During the Middle Ages, Icelanders called the volcano the "Gateway to Hell."

Eyjafjallajökull, Iceland

Eyjafjallajökull (E15) is one of the smaller ice caps of Iceland, situated to the north of Skógar and to the west of Mýrdalsjökull. The ice cap covers the caldera of a volcano with a summit elevation of 1,666 metres. The volcano has erupted relatively frequently since the last glacial period, most recently in 2010 and put international Air Traffic at a standstill for days.
