The most fatal volcanic eruption of Iceland's history was the so-called Skaftáreldar (fires of Skaftá) in 1783–84. The eruption was in the crater row Lakagígar (craters of Laki) southwest of Vatnajökull glacier. The craters are a part of a larger volcanic system with the subglacial Grímsvötn as a central volcano.

Postglacial volcanism is conﬁned to the neovolcanic zones where 30 active volcanic systems are responsible for most of the Holocene activity. On the basis of our current post-glacial eruptiondata set we estimate that Icelandic volcanism has produced around 2400 eruptions and about 566±100 km3of erupted magma in the last 11 ka.

Postglacial Icelandic shield volcanoes were formed in monogenetic eruptions mainly in the early Holocene epoch. Shield volcanoes vary in their cone morphology and in the areal extent of the associated lava flows. This paper presents the results of a study of 24 olivine tholeiite and 7 picrite basaltic shield volcanoes. For the olivine tholeiitic shields the median slope is 2.7°, the median Four major NE trending postglacial volcanic and tectonic fissure swarms (volcanic systems) occur on the Reykjanes Peninsula, and the westernmost three are the main subject of this paper. Two main types of basaltic volcanoes are associated with these systems: shields of picrite and olivine tholeiite and tholeiite fissures.

Tephrochronological dating of postglacial volcanism in the Dyngjufjöll volcanic complex, a major spreading center in the Icelandic Rift Zone, indicates a high production rate in the millennia following deglaciation as compared to the present low productivity. The visible and implied evidence indicates that lava production in the period 10 000 4500 bp was at least 20 to 30 times higher than

9 Mar 2021 Iceland was shaken by 20000 earthquakes in 7 days. Experts say a volcanic eruption is imminent. The last time a volcano erupted in Iceland,

This upwelling generates the melt that crystallizes to form the thick Icelandic crust. The bulk of the plate divergence occurs in active rift zones, which host many young basaltic eruptions. Postglacial Icelandic shield volcanoes were formed in monogenetic eruptions mainly in the early Holocene epoch. Shield volcanoes vary in their cone morphology and in the areal extent of the associated lava flows. This paper presents the results of a study of 24 olivine tholeiite and 7 picrite basaltic shield volcanoes. Gudmundur E Sigvaldason, Kristian Annertz, Magnus Nilsson, Effect of glacier loading/deloading on volcanism: postglacial volcanic production rate of the Dyngjufj ll area, central Iceland, Bulletin of Volcanology, 10.1007/BF00312320, 54, 5, (385-392), (1992). The evidence for periods of increased volcanic activity following deglaciation, such as following ice sheet retreat after the Last Glacial Maximum, has been examined in several formerly glaciated areas, including Iceland, Alaska, and the Andean Southern Volcanic Zone.

Recent research has changed this picture. Central volcanoes producing acid and intermediate lava and tephra have played a considerable role both in the GUDMUNDSSON, A 1986, ' MECHANICAL ASPECTS OF POSTGLACIAL VOLCANISM AND TECTONICS OF THE REYKJANES PENINSULA, SOUTHWEST ICELAND ', … Icelandic Inst Nat Hist, Reykjavik.
