    The Breiðdalur volcanic system, eastern Iceland, comprises of a ~600 km3 central volcano, a 30 - 40 km long dyke swarm and plateau basalts erupted from this dyke swarm. The entire volcanic system was active from 10.1 to 7.8 Ma, the central volcano was ...
  • Bjarnason, Ingi Þorleifur (Iceland Glaciological Society and Geoscience Society of IcelandJöklarannsóknafélags Íslands og Jarðfræðafélags Íslands, 2008)
    Is Iceland a hotspot, with ridge-centered plume? In Iceland vigorous volcanism has built up a plateau 3.0 km higher than at a normal mid-ocean ridge with 3 to 4 times thicker crust than average oceanic crust. This volcanism can be associated with ...

    The 6-month long eruption at Holuhraun (August 2014–February 2015) in the Bárðarbunga-Veiðivötn volcanic system was the largest effusive eruption in Iceland since the 1783–1784 CE Laki eruption. The lava flow field covered ~84 km2 and has an estimated ...

    Climate change is contributing to shifts in the magnitude and scale of hazards, and the emergence of risks in areas where they were previously unknown. In south-east Iceland, a fracture in the mountainside of Svínafellsheiði threatens to cause between ...
  • Möller, Rebecca; Dagsson-Waldhauserova, Pavla; Möller, Marco; Kukla, Peter; Schneider, Christoph; Gudmundsson, Magnus Tumi (Elsevier BV, 2019-11)
    In April and May 2010 the Icelandic volcano Eyjafjallajökull experienced an explosive eruption that led to substantial ashfall across the central-southern parts of the island. The resulting ash deposits covered Eyjafjallajökull, Mýrdalsjökull and parts ...

    The 2017 Surtsey Underwater volcanic System for Thermophiles, Alteration processes and INnovative concretes (SUSTAIN) drilling project at Surtsey volcano, sponsored in part by the International Continental Scientific Drilling Program (ICDP), provides ...
  • Caracciolo, Alberto (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2021-02)
    The physico-chemical properties of magma storage reservoirs in multi-level magmatic systems may change with time, along with the timescales at which crystals and melts are processed throughout the crust. In this thesis, I use an integrated approach ...
