(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2020-01)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 ... -
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2017-07-14)The 10th century Eldgjá flood lava eruption, southern Iceland, was the most voluminous eruption on Earth in the last 1100 years, erupting up to 21.0 km3 of transitional alkali basaltic magma of rather uniform composition. While 19.7 km3 was erupted as ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2022-12)Post-eruptive deformation following volcanic eruptions may originate from continued magma movements, or reflect delayed and continued Earth adjustment due to co-eruptive events, often referred to as viscoelastic relaxation. Post-eruptive deformation ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2021-10)In this study, the magmatic evolution and the eruptive history of the Paka volcanic complex are investigated and its geothermal reservoir is assessed. The study comprises two parts. The first part deals with the eruptive history, magma evolution, and ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2017-12-18)Thermal anomalies are observed at many volcanoes, resulting from geothermal and magmatic activity, and are usually difficult to quantify since the measurement of heat fluxes from the ground to the atmosphere is subject to large uncertainties. However, ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2021)Flood lavas (FL), or high magnitude (1–100 km3) basaltic fissure eruptions have a recurrence interval of 250–500 years in Iceland. These events can produce atmospheric volcanic pollution at tropospheric–stratospheric levels via their sulfur (S) emissions. ...

(PhD-defence at University of Copenhagen, 2017-08-25)Iceland is one of the most active terrestrial volcanic regions on Earth with an average of more than 20 eruptions per century. Around 80% of all events are tephra generating explosive eruptions, but less than 10 % of all known tephra layers have been ...
