Bardarbunga – Holuhraun Fissure Eruption

Bardarbunga 2014-2015: Holuhraun Fissure Eruption Video

In the early hours of 29 August 2014, a small fissure eruption occurred in Holuhraun at the northern end of a magma intrusion which had moved progressively north, since 16 August, from the Bárðarbunga volcano. The progression of the magma intrusion was accompanied by an earthquake swarm. The eruption began just after midnight and stopped at 04:00 GMT. The active fissure was about 600 m (660 yd) in length.

Another fissure eruption started in Holuhraun at around 05:05 GMT on the morning of 31 August 2014, in the same rift as the eruption which had occurred two days earlier.[12] The eruptive fissure was estimated to be 1.5 km (0.93 mi) long.[11] By 4 September, the total area of the lava flow was estimated at 10.8 km2 (4.2 sq mi).[11] Two new eruptive fissures formed south of the main eruption site, on 5 September.[11] The new fissures were substantially smaller than the older fissure.[11] By 7 September, the lava flow had extended 11 km (6.8 mi) to the north, and had reached the main western branch of the Jökulsá á Fjöllum river. The eruption showed no visible activity in the southern fissure, on the evening of 7 September. The lava flow is considered to be the largest in recent decades in Iceland and covered 44 km2 (17 sq mi) on 29 September.[13] The volcanic eruption in Holuhraun continues with similar intensity as the last few weeks. The lava field covered 63 km2 (24 sq mi) in late October. On 11 November it was reported that the lava field extends to 70 km2 (27 sq mi) and more than 1 km3 (0.24 cu mi) in volume – the largest in Iceland since the Laki eruption of 1783. The eruption ended on February 27th, 2015. The Nornahraun lava field measures more than 85 square km.
