The 2010 eruptions of Eyjafjallajökull are a series of major volcanic events at Eyjafjallajökull in Iceland. They caused significant disruption to air travel across western and northern Europe in 2010. Seismic activity started at the end of 2009 and led to a volcanic eruption of Volcanic Explosivity Index (VEI) 1 on 20 March 2010.[1] The plume of ash from a later ongoing eruption beginning on 14 April 2010 led to widespread disruption of air travel from 15 April, with much of the airspace in Europe closed until 20 April, causing cancellation of most flights within, to, and from Europe. Eyjafjallajökull (pronounced [ˈɛɪjaˌfjatlaˌjœkʏtl̥], About this sound listen (help·info)) is one of the smaller glaciers of Iceland. It is situated to the north of Skógar and to the west of the larger glacier Mýrdalsjökull. The icecap of the glacier covers a volcano 1666 metres (5466 ft) in height that has erupted relatively frequently since the last Ice Age. The most recent major eruptions occurred in 920, 1612 (believed to have lasted only three days) and from 1821 to 1823 (on and off for more than a year). Previous eruptions of Eyjafjallajökull have been followed by eruptions at its larger neighbour, Katla on 20 April 2010 Icelandic President Ólafur Grímsson said that “the time for katla to erupt is coming close … we [Iceland] have prepared … it is high time for European governments and airline authorities all over the world to start planning for the eventual Katla eruption”
