Description:

An earthquake swarm began under Eyjafjoll volcano in January 2010. There was a 40 mm inflation of the volcano. At the beginning of March 2010 over 3000 earthquakes were measured in a 24 hour period, with a maximum at magnitude 3.1. The last eruptions at Eyjafjoll volcano were in 1821-23.

The subglacial Esjufj�ll volcano at the SE part of the Vatnaj�kull icecap, north of �raefaj�kull volcano, consists of the Snaehetta central volcano and a large caldera. Most of the volcano, including the 40 sq km caldera, is covered by the icecap, but parts of the SE flank are exposed in NW-SE-trending ridges. Most of the exposed rocks are mildly alkaline basalts, but small amounts of rhyolitic rocks are also present. A large j�kulhlaup that came down the Jokulsa a Breidamerkursandi along the coast SE of Vatnaj�kull in the beginning of September 1927 was accompanied by a sulfur stench, and on one occasion, ash fall on the Breidamerkurj�kull considered to have possibly originated from Esjufj�ll. Although Holocene eruptions have not been confirmed from Esjufj�ll, earthquake swarms that could indicate magma movements were detected in October, 2002.
