The Tungnafellsjökull central volcano, located immediately NW of the massive Vatnajökull icecap, contains two calderas. One is largely filled by the Tungnafellsjökull glacier, and the other ice-free caldera located to the SE contains Pleistocene rhyolitic lavas. The 1535-m-high Tungnafellsjökull volcano is largely of Pleistocene age, but postglacial flank fissures on the NE side have produced young basalts. The Hágöngur central volcano to the SW is part of the Tungnafellsjökull volcanic system.

The Global Volcanism Program is not aware of any Holocene eruptions from Tungnafellsjokull. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Tungnafellsjokull page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The small Tungnafellsjökull central volcano lies immediately to the NW of the massive Vatnajökull icecap, which is visible at the upper left. Tungnafellsjökull contains two calderas. One is largely filled by the Tungnafellsjökull glacier (center), and the other ice-free caldera is located to the SE (left) and contains Pleistocene rhyolitic lavas. Tungnafellsjökull volcano is largely of Pleistocene age, but postglacial flank fissures on the NE side have produced young basaltic lava flows.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. 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.
