The small circular area just right of the center of this Space Shuttle image is Deriba caldera, the most prominent feature of the vast Jebel Marra volcanic field in western Sudan. The 5-km-wide, steep-walled caldera was formed about 3500 years ago at the time of the eruption of voluminous airfall pumice and pyroclastic flows that traveled more than 30 km from the volcano. Ash eruptions may have continued into early historical time, and fumarolic activity continues on the flanks of the caldera.

A lake partially fills a younger cone within the Deriba caldera of Jebel Marra volcano in this view from the north. The 5-km-wide, steep-walled Deriba caldera, whose wall appears in the background, was formed about 3500 years ago at the time of the eruption of voluminous airfall pumice and pyroclastic flows that traveled more than 30 km from the volcano. Post-caldera ash eruptions may have continued into historical time.
