A close-up night view of the lava flow and massive plumes. Holuhraun Fissure, near the Bardarbunga Volcano, Iceland. Sept. 2, 2014. Holuhraun is a lava field created by fissure eruptions in the Icelandic Highlands. August 29, 2014, a fissure eruption occurred in Holuhraun at the northern end of a magma intrusion which had moved progressively north, from the Bardarbunga volcano. Bardarbunga is a subglacial stratovolcano located under the ice cap of Vatnajokull glacier within the Vatnajokull National Park situated about 15 km (9.3mi) from the Holuhraun lava field.

A close up of lava from an eruption on Holuhraun, northwest of the Dyngjujoekull glacier in Iceland, Monday, Sept. 1, 2014. Lava fountains danced along a lengthy volcanic fissure near Iceland's subglacial Bardarbunga volcano Sunday, prompting authorities to raise the aviation warning code to the highest level and close the surrounding airspace. The warning was lowered 12 hours later as visibility improved and it was clear that no volcanic ash was detected. (AP Photo/Eggert Johannesson)
In this aerial view, fountains of lava, up to 60 meters high, spurt from a fissure in the ground on the north side of the Bardarbunga volcano in Iceland, Tuesday, Sept. 2, 2014. The alert warning for the area surrounding Iceland's Bardarbunga volcano remained at orange on Tuesday, indicating that it is showing increased unrest with greater potential for an explosive eruption.
