Mighty eruptions at a volcano in Iceland involve huge amounts of lava, so it’s no surprise the Bardarbunga volcano lies directly over the hottest portion of the North Atlantic mantle plume, researchers say.
The volcano in central Iceland, which has been ejecting huge amounts of lava since Aug. 31, is evidence that such eruptions require extremely high mantle temperatures deep beneath the Earth’s surface to generate such massive amounts of magma, scientists from the University of California Davis and Denmark’s Aarhus University say.
