Ehi Mousgou

Voon, Tarso

Stratovolcano · Chad · 3100m

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. 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.

Geological summary

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. It 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.
