Volcanism in Iceland in historical time: Volcano types, eruption styles and eruptive history
TL;DR: In this paper, the authors identified 205 eruptions in historical time by detailed mapping and dating of events along with extensive research on documentation of volcanic activity in historical chronicles and classified them into three categories: effusive, effusive and mixed.

TL;DR: The 39-day long eruption at the summit of Eyjafjallajökull volcano in April–May 2010 was of modest size but ash was widely dispersed, combining data from ground surveys and remote sensing to show that the erupted material was 4.8±1.2·1011 kg.
Journal ArticleDOI
Geochemistry of historical-age silicic tephras in Iceland:
TL;DR: The major element chemistry of nine silicic tephras of historical age from Iceland is assessed as a key step in the development of the recent tephrochronology of the North Atlantic region as discussed by the authors.
Journal ArticleDOI

Sigurdur R. Gislason,Tue Hassenkam,S. Nedel,Nicolas Bovet,Eydis Salome Eiriksdottir,H.A. Alfredsson,Caroline Piper Hem,Z. Balogh,Knud Dideriksen,Niels Oskarsson,Bergur Sigfússon,Gudrún Larsen,Susan L. S. Stipp +12 more
TL;DR: The physical and chemical nature of the ash was explored to determine if fears about health and safety were justified and a protocol was developed that will serve for assessing risks during a future event.
Journal ArticleDOI
Recent volcanic history of the Veidivötn fissure swarm, southern Iceland — an approach to volcanic risk assessment
TL;DR: The recent volcanic history of the southwestern part of the Veidivotn fissure swarm, southern Iceland, provides a basis for assessment of volcanic risk in an area of large hydropower potential as mentioned in this paper.
