Iceland has a high concentration of active volcanoes due to unique geological conditions. The island has about 130 volcanic mountains, of which 18 have erupted since the settlement of Iceland in 874 AD. Over the past 500 years, Iceland's volcanoes have erupted a third of the total global lava output. Although the Laki eruption in 1783 had the largest eruption of lava in the last 500 years, the Eldgjá eruption of 934 AD and other Holocene eruptions were even larger. | | |Location |Iceland | |Coordinates |[pic]63°38′N 19°36′W / 63.633°N 19.6°W / 63.633; -19.6 | |Area |100 km2 (40 sq mi) | |Thickness |28018 |
The most recent[update] volcanic eruption in Iceland was that of Eyjafjallajökull, which started on April 14, 2010. The Eyjafjallajökull eruption closely followed an eruption in Fimmvörðuháls, which had erupted on March 20, temporarily quiesced by April 12, and then erupted with a large ash plume (due to magma coming out under ice) on April 15. The ash cloud was significant enough to shut down airports across more than 20 European countries, many of which only began to reopen on April 20. The 2010 eruptions of Eyjafjallajökull were a sequence of major volcanic events at Eyjafjallajökull in Iceland which disrupted air travel across western and northern Europe over an initial period of 6 days in April 2010. Further more localized disruption continued into May 2010.
