Grimsvötn volcano is located under Vatnajökull ice cap in central Iceland. Two major volcanic centers lie beneath the ice, the Bardarbunga volcanic centre and the Grimsvötn volcanic centre. Grimsvötn centre is the more active of the two.
About every 5-10 years glacial melting causes large floods (jökulhlaup) on the sandur plain. Eruptions at Grimsvotn Volcano are phreatomagmatic..
