Tarso Toussidé, a broad volcanic massif at the western end of the Tibesti Range, is capped by the Toussidé stratovolcano, constructed at the western end of the 14-km-wide ignimbritic Yirrigue caldera of Pleistocene age. The 6000 sq km Toussidé massif was constructed over a basement of Precambrian schists on the east and Paleozoic sandstones on the west. The summit of Toussidé contains numerous fumaroles and very youthful lava flows that would be of historical age in an inhabited region (Vincent 1992, pers. comm.). Fresh-looking trachytic and trachyandesitic lava flows from Toussidé cover an area of 200 sq km and extend as far as 25 km from the summit on the western side. The steep-sided, 1-km-deep, 8-km-wide Trou au Natron caldera cuts the SE rim of Yirrigue caldera and is one of the youngeset features of the massif. Ehi Timi and Ehi Sosso volcanoes and the smaller 1.5-km-wide explosion crater of Doon Kidimi are located on the NE-to-ESE flanks of the massif.

The Global Volcanism Program is not aware of any Holocene eruptions from Tarso Toussidé. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Tarso Toussidé 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.

Dark lava flows radiate from Toussidé volcano (center), the second highest peak of the Tibesti Range in Chad. This Space Shuttle image of the Tarso Toussidé volcanic massif has north to the bottom. Toussidé stratovolcano was constructed at the western end of the large Pleistocene ignimbritic caldera of Yirrigue, whose scarp is seen left of Toussidé. The smaller 8-km-wide caldera of Trou au Natron cuts the SE rim of Yirrigue caldera. Ehi Timi (lower center) and Ehi Sosso (left center) volcanoes are located on the flanks of the massif.

A dramatic Space Shuttle image shows dark lava flows radiating from Toussidé volcano and spreading across the desert floor. Light-colored fumarolically altered areas can be seen at the volcano's 3265-m-high summit, the second highest peak of the Tibesti Range in Chad. Toussidé stratovolcano was constructed at the western end of the large Pleistocene ignimbritic caldera of Yirrigue, whose eastern scarp is seen right of Toussidé. The smaller 1000-m-deep, 8-km-wide Trou au Natron caldera (lower right) cuts the SE rim of Yirrigue caldera.

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.
