2010 eruptions of Eyjafjallajökull

The 2010 eruptions of Eyjafjallajökull were a period of volcanic events at Eyjafjallajökull in Iceland which, although relatively small for volcanic eruptions, caused enormous disruption to air travel across western and northern Europe over an initial period of six days in April 2010. Additional localised disruption continued into May 2010, and eruptive activity persisted until June 2010. The eruption was declared officially over in October 2010, after 3 months of inactivity, when snow on the glacier did not melt. From 14–20 April, ash from the volcanic eruption covered large areas of Northern Europe. About 20 countries closed their airspace to commercial jet traffic and it affected approximately 10 million travellers.
Seismic activity started at the end of 2009 and gradually increased in intensity until on 20 March 2010, a small eruption began, rated as a 1 on the volcanic explosivity index.
