Iceland is situated on top of a so called hotspot, this means that it experiences severe volcanic activity. There is no immideate threat to life on this little island but the effects of larger eruptions can be difficult to predict. The widely known volcanic glacier Eyjafjallajokull (elev. 1,666 m) erupted in 2010, sending ash high into the atmosphere and seriously disrupting European air traffic. Scientists continue to monitor the nearby Icelandic Volcano Katla (elev. 1,512 m), which has a high probability of eruption in the very near future, potentially disrupting air traffic. Grimsvotn and Hekla are Iceland's most active volcanoes but other historically active volcanoes include Askja, Bardarbunga, Brennisteinsfjoll, Esjufjoll, Hengill, Krafla, Krisuvik, Kverkfjoll, Oraefajokull, Reykjanes, Torfajokull, and Vestmannaeyjar.
The Volcano Hekla
Hekla, located in the south of Iceland amidst the Fjallabak mountain range, is one of the most active volcanoes in Iceland.In holding up its reputation as one of the most active volcanoes in Iceland, Hekla has seen over 20 eruptions since 874, being referred to as the "Gateway to Hell,” dating back to the Middle Ages.
The Icelandic volcano, Eyjafjallajokull, is one of Iceland's smallerice caps located in the far south of the island. As one of the more famous Icelandic volcanoes, it’s situated to the north of Skogar and to the west of the larger ice cap Myrdalsjokull.The ice cap covers the caldera of a volcano 1,666 metres (5,466 ft) high, which has erupted relatively frequently since the last ice age. The mountain itself, a stratovolcano, stands at 1,651 metres (5,417 ft) at its highest point, and has a crater 3–4 kilometres (1.9–2.5 mi) in diameter, open to the north.
