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.
