Intrusion triggering of the 2010 Eyjafjallajökull explosive eruption

Abstract
The deformation style at moderately active volcanoes [mdash] such as Eyjafjallajokull, Iceland, which underwent an explosive summit eruption earlier this year [mdash] is little understood. These authors show that deformation associated with the eruptions at Eyjafjallajokull was unusual as it did not relate to pressure changes within a single magma chamber, and infer that this behaviour might be attributed to its off-rift setting with a 'cold' subsurface structure and limited magma at shallow depth.
