The Eruption of Fimmvörduháls - volcano close to Eyjafjallajökull at Iceland in March 2010. This eruption was the first part of the Eyjafjallajökull-eruption. I climbed the volcano together with my friend Martin and spend the night close to the site of eruption. It was a cold, but very exciting night.
Background:
Eyjafjallajökull is a 1666-m-high volcano in south Iceland. It is located west of Katla volcano. Both volcanoes are ice-covered. Eyjafjallajökull consists of an E-W-trending, elongated stratovolcano. On the top is a 2.5-km-wide summit caldera. Lava flows occur on both the E and W flanks, but are more prominent on the western side.
Although the volcano has erupted during historical time, it has been less active than other volcanoes of Iceland's eastern volcanic zone. The last historical activity prior to an eruption in 2010 took place during December 1821 to January 1823 and produced intermediate-to-silicic tephra from the central caldera.
During March 2010, the scientist of IMO and IES reported the first eruption of Eyjafjallajökull volcano since 1823.
From 20 March to 12 April 2010 the eruption's first phase occurred from a fissure at Fimmvörðuháls, located between the Eyjafjallajökull and Mýrdalsjökull glaciers. These vents along the fissure on the lower E slopes were snow-covered but not under the year-round icecap. Lava flows filled gullies, and formed a lava fall direction Thorsmörk.
After a break of the fissure activity on 12 April, a second phase of the eruption began on 14 April generating ash plumes that blew E to Europe and resulted in decrease of airline flights for as much as a week. Because of the flight cancellations, the eruption of Eyjafjallajökull became one of the most prominent eruptions in past decades. (Sources: USGS/WIKIPEDIA/volcanoes.de)
