Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Hofsjokull
The broad Hofsjökull volcano lies beneath the western part of the massive Hofsjökull icecap. A caldera 7-8 km wide is beneath about 700 m of ice to the right of the high point in this view from the NNW. Lava flows are found to the south, east, and north of this central volcano. The rugged ice-covered peak at top right is the Kerlingarfjöll edifice. Photo by Oddur Sigurdsson, 1978 (Icelandic National Energy Authority).

Hofsjökull volcano lies along an east-west-trending area connecting the two principal rift zones of Iceland. It bridges the gap between the Reykjanes-Langjökull rift on the west, which terminates at Langjökull, and the eastern zone, which extends NE-ward across east-central Iceland. The roughly 7 x 11 km central caldera lies beneath the western part of the massive Hofsjökull icecap. A small Holocene shield volcano is located at the SW margin of the icecap. Flank fissures north and east of the icecap have produced basaltic lava flows during the Holocene. Kerlingarfjöll, a glacially dissected, largely Pleistocene rhyolitic central volcano located SW of the Hofsjökull icecap, is considered part of this volcanic system. Steep-sided Pleistocene rhyolitic lava domes and numerous hot springs occupy two calderas at the center of the 5 x 7 km wide complex. Fumarolic activity at Kerlingarfjöll, mostly concentrated in the center of the complex, is the most vigorous in Iceland.
