The broad summit of Tarso Voon volcano, located in the west-central part of the Tibesti Range, is truncated by a shallow 14 x 18 km wide caldera. Ignimbrite deposits surround the caldera to distances of 15-35 km. Tarso Voon was constructed over a basement of Precambrian schists. Youthful-looking Quaternary basaltic lava flows have been erupted from vents near the caldera rim over a 180 degree area extending counterclockwise from the NE and from Ehi Mousgau, a 3100-m-high stratovolcano located to the NW. The Soborom solfatara field, the largest in the Tibesti Range, is located in an area of volcano-tectonic uplift 5 km west of the caldera rim. Its fumaroles, active mud pots, and boiling waters are visited by Tibesti peoples for medicinal uses.

The Global Volcanism Program is not aware of any Holocene eruptions from Tarso Voon. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Tarso Voon 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 circular area near the center of this Space Shuttle image is the shallow 14 x 18 km wide summit caldera of Tarso Voon volcano in the west-central part of the Tibesti Range. Youthful-looking Quaternary basalts were erupted from vents near the caldera rim and from Ehi Mousgau, a small stratovolcano visible to the NW. The large Soborom solfatara field west of the massif, with its active mud pots and boiling waters, is visited by Tibesti peoples for medicinal uses. Pleistocene Tarso Yéga caldera to the SE is at the lower right.

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.
