Earthquakes at shallow depths (around 5 km) continue at reduced rate. [more]
Bárdarbunga volcanoBárdarbunga, a large central volcano, had its last major eruption in 1477 when it produced a large ash and pumice fall-out deposit. It also produced the largest known lava flow during the past 10,000 years on earth (more than 21 cubic kilometers of volume).
Background:The volcano is hidden beneath the northwestern part of the Vatnajökull glacier, and contains a 700-m-deep caldera that is hidden beneath ice and has extensive flank fissures, from where eruptions have taken place: the Veidivötn fissure extends for over 100 km to the SW, almost reaching Torfajökull volcano, while the Trollagigar fissure extends 50 km to the NE touching Askja volcano.
A major risk from Bárdarbunga are jökulhlaups (glacier-outburst floods), that can be hazardous for areas in all directions around Bárdarbunga.
