There are no Holocene eruptions known for Hofsjökull. If this volcano has had large eruptions prior to 10,000 years ago, information might be found in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title. Additional discussion of data sources can be found under Volcano Data Criteria.

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 of Hofsjökull volcano 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 the Hofsjökull 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.
