TL;DR: It is concluded that interaction between the pressure exerted by the subsiding reservoir roof and the physical properties of the subsurface flow path explain the gradual near-exponential decline of both the collapse rate and the intensity of the 180-day-long eruption of the Bárdarbunga volcano.

TL;DR: The 2014-2015 Barðarbunga eruption was the largest in Iceland for more than 200 years, producing 1.6 ± 0.3 km3 of lava.

TL;DR: The 2014-2015 Holuhraun eruption in Iceland, emitted ∼11 Tg of SO2 into the troposphere over 6 months, and caused one of the most intense and widespread volcanogenic air pollution events in centuries as mentioned in this paper.
Journal ArticleDOI

TL;DR: The 2014-2015 Barðarbunga fissure eruption at Holuhraun was distinguished by high emission of gases, in total 9.6 Mt SO2, with almost no tephra as discussed by the authors.
Journal ArticleDOI
Degassing regime of Hekla volcano 2012-2013

TL;DR: In this paper, the authors used reaction path modelling to derive information on the origin and reaction pathways of the gas emissions at Hekla and concluded that a compositional shift towards more S- and H2O-rich gas compositions should be viewed as a sign of imminent volcanic unrest on Hekala.
