The Bárdarbunga/Holuhraun eruption 2014-2015

The Bárdarbunga/Holuhraun eruption 2014-2015

An eruption lasting for 6 months occurred 2014-2015 in Holuhraun lavafield, north of Vatnajökull, on the Bárdarbunga volcanic system. The eruption started 29 August 2014 and effusive activity continued until 27 February 2015. The Vatnajökull glacier covers both central volcanoes and in total ~33% of the volcanic system. Bárðarbunga is the most extensive volcanic system in Iceland, reaching 190 km from the southernmost point to the northernmost. It is the second most active volcanic system in the country with 26 known eruptions during the last 1100 years. Most eruptions are explosive basaltic eruptions but large effusive eruptions are known, such as the Þjórsárhraun that was formed ~8600 years ago and flowed 130 km following river channels.

Bárðarbunga and Holuhraun - an overview and links

An overview of the Bárðarbunga seismic events and the Holuhraun eruption, 2014-2015, is given here with notes, factsheets and observations. New material was added to the top of each monthly article. Combined, the monthly articles give an overview of events, see: August, September, October, November, December, January, February, March-April-May and this overview.
