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 3,500 years ago during an eruption that produced 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 N. The 5-km-wide, steep-walled caldera, whose wall appears in the background, was formed about 3,500 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.

The 5-7 km Deriba caldera is part of the Jebel Marra volcanic field, located in the Darfur province of western Sudan, shown in this November 2019 Planet Labs satellite image monthly mosaic (N is at the top). It formed during an eruption 3,500 years ago that produced pyroclastic flows reaching 30 km away. The central lake is within the crater of a smaller cone.
