The 2011 eruption of Grímsvötn was a Plinian eruption of Grímsvötn, Iceland's most active volcano, which caused disruption to air travel in Northwestern Europe from 22–25 May 2011. The last eruption of Grímsvötn was in 2004, [ 2 ] with the previous most powerful eruptions in 1783, 1873 and 1902.
It is believed that the four eruptions between 1996 and 2011 could mark the beginning of an active period, during which an eruption in Grímsvötn in Vatnajökull may be expected every 2–7 years. Parallel volcanic activity in nearby Bárðarbunga is known to be associated with increased activity in Grímsvötn. Seismic activity has been ...
The eruption in May 2011 at Grímsvötn under the Vatnajökull glacier sent thousands of tonnes of ash into the sky in a few days, raising concerns of the potential for travel chaos across northern Europe although only about 900 flights were initially disrupted. [35]

Including the Skaftá eruption of 1783, Grímsvötn is probably the most eruptive volcano system in Iceland. The Laki/Lakagígar lava field alone is estimated to have produced about 15 cubic kilometres (3.6 cu mi) of lava.

Explosive basaltic eruptions with tephra and lava with jökulhlaups. The Þórðarhyrna (Thordarhyrna) central volcano is not definitely part of the Grímsvötn volcanic system and may be a separate volcanic system.
