Tarso Toussidé, Stratovolcano in Tibesti Region, Chad
Tarso Toussidé is a stratovolcano in the Tibesti Region reaching 3,265 meters with a prominent lava dome at its summit. Multiple calderas surround the volcano, and lava flows extend across the landscape with surfaces ranging from bubbly to glassy textures.
Explorers Jean Tilho and W.G. Tweedale mapped and measured this volcano in 1920, correcting earlier records that underestimated its height. Their fieldwork established the mountain's true elevation and brought scientific attention to the Tibesti Region.
The name comes from local Tibesti language, where Tarso means high mountain plateau. This linguistic connection reflects how the region's people have long understood and named their landscape.
The terrain around the volcano is demanding with varied lava surfaces and requires sturdy footwear and good physical fitness. Visitors should prepare for extreme conditions and bring a local guide, as the region is very remote and difficult to access.
Active fumaroles at the summit release steam at temperatures between 40 to 60 degrees Celsius, showing that volcanic activity continues beneath the surface. Visitors can witness these gas vents releasing water vapor and feel the heat they produce.
