Of these 30 active volcanic systems, the most active is Grímsvötn. Over the past 500 years, Iceland's volcanoes have produced a third of the total global lava output. Important eruptions Laki/Skaftáreldar 1783-84. The most fatal volcanic eruption of Iceland's history was the so-called Skaftáreldar (fires of Skaftá) in

Postglacial activity on the Askja volcanic system, north Iceland, has been dominated by basaltic volcanism. Over 80% of Askja's postglacial basalts fall within a relatively narrow compositional range containing between 4 and 8 wt.% MgO.

At 21:20 UTC and earthquake with magnitude of Mw3,1 took place and at 23:29 UTC an earthquake with magnitude of Mw3,2 took place. 1986-11-10 Several recent studies have highlighted the potential of combined 238 U– 230 Th and 235 U– 231 Pa systematics to constrain upwelling rates and the role of recycled mafic lithologies in mantle plume-derived basalts.

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.

Volcanism in Iceland is the surface expression of the interaction of the deep mantle plume beneath Iceland with a constructive tectonic plate boundary (the mid-Atlantic ridge; figure 1), at which the European and north american plates are moving apart at about 20 mm/yr. throughout Iceland a number of volcanic

Comparison with a temperature index shows that clustered New field observations, age constraints, and extensive chemical analyses define the complete postglacial eruptive history of the 170-km-long Western Volcanic Zone (WVZ) of Iceland, the ultraslow-spreading western boundary of the south Iceland microplate. We have identified 44 separate eruptive units, 10 of which are small-volume eruptions associated with the flanking Grimsnes system.

Pringle and Scott: Postglacial Influence of Volcanism on the Puget Lowland All Washington volcanoes except for Mount Adams have erupted since the birth of the United States in 1776, and all of them, as well as Mount Hood, have active seismicity and/or geothermal activity. Volcanism in Iceland is diverse, spanning almost the range of common terrestrial magma types and eruption styles (e.g.
