The Askja central volcano in northern Iceland has been continuously subsiding at least since 1983. GPS and optical leveling tilt measurements show subsidence of at least 75 cm from 1983 to 1998 in the center of the Askja caldera, without any eruptive activity. We have performed an ...

While it claimed no lives directly, the explosive 1875 eruption of Askja volcano in central Iceland may have had even more significant long-term repercussions as it has been implicated in the emigration of nearly 1200 people, around 1.7% of the population, who left the island for North Amer-...
Abrupt shifts between wet and dry phases of the 1875 eruption of Askja Volcano: Microscopic evidence for macroscopic dynamicsaskja 1875vesiculationphreatoplinianeruption dynamicsThe eruption of Askja in 1875 was a powerful eruption with intervals of sustained activity, yet also with abrupt shifts in...
Subsidence within the main caldera of Askja volcano in the North of Iceland has been in progress since 1983. Here, we present new ground- and satellite-based deformation data, which we interpret together with new and existing micro-gravity data, to help understand which processes may be ...

The nature and reasons for such shifts are poorly understood, yet are critical to our ability to mitigate future volcanic hazards from these volcanic centers.;The 1875 rhyolitic eruption of Askja Volcano was characterized by intervals of sustained activity, yet also with abrupt shifts in eruption ...
Austurfjoll is the largest basaltic glaciovolcanic massif at Askja volcano (Central Iceland), and through detailed studies of its volcanological and geochemical characteristics, we provide a detailed account of the sequence and structure of the ice-confined construction of a large Icelandic basaltic ...
Activity within magmatic divergent plate boundaries (MDPB) focuses along both regional fissure swarms and central volcanoes. An ideal place to investigate their mutual relationship is the Askja central volcano in Iceland. Askja consists of three nested calderas (namely Kollur, Askja and Öskjuvatn...
