The 2014-15 Bárðarbunga-Holuhraun magmatic rifting episode: A seismic study
… near the southeastern rim of the ice-covered Bárðarbunga caldera in central Iceland. Over the course of two weeks a dyke propagated 48 km beneath the glacier northeastwards and into the Holuhraun lava field, where it erupted for six months, becoming the largest eruption in Iceland for over 200 …

Dyke-induced earthquakes during the 2014-15 Bárðarbunga-Holuhraun rifting event, Iceland
… and as conduits that feed eruptions. The 2014-15 Bárðarbunga-Holuhraun rifting event comprised the best-monitored dyke intrusion to date and the largest eruption in Iceland in 230 years. Over a 13 day period magma propagated laterally from the subglacial Bárðarbunga volcano, Iceland, along a 48 km …

Dynamic Poroelastic Finite Element Deformation Modelling of the Bárðarbunga Volcano, Iceland, 2015-2024
… post-eruptive (2015 – 2024) deformation of the Bárðarbunga volcano to constrain the likely magma supply and storage characteristics. Initial exploratory modelling was undertaken using 2D-axisymmetric FE models to investigate the general effects on surface deformation of poroelastic reservoir …

Towards monitoring volcanoes in Iceland and Hawai’i with seismic velocity variations
… and dilatation associated with the 2014 Bárðarbunga-Holuhraun dyke intrusion. The intense seismicity associated with the subsequent rifting event alters the CCFs, making measurements of dv/v unreliable during the 6-month eruption. However, volcanic tremor can be located by measuring the …

Timescales of magma residence and transport underneath Iceland
… and transport: the Skuggafjöll eruption, Bárðarbunga volcanic system; the Borgahraun eruption, Theistareykir volcanic system; and the Laki eruption, Grímsvötn volcanic sytem. These findings are then synthesised within an Icelandic and global framework. The Skuggafjöll eruption contains …

Tectonic earthquake swarms in the Northern Volcanic Zone, Iceland
… fast and potentially devastating fault slip. The Bárðarbunga-Holuhraun dike intrusion provides a unique opportunity to analyse the triggering of seismic swarms due an extremely well-resolved static stress change. As the dike intruded towards Askja, a surge in swarm seismicity was observed across …
