Jebel Marra Volcano, Sudan – January 12th, 2009
This excellent view of Darfur, Sudan highlights the Jebel Marra Volcano and the Marra Mountains.
The Marra mountains rise steeply from the flat plains of western Sudan at about 1000 m elevation to just under 3000 m above sea level.
In the close-up image, we can see the volcano’s collapsed mouth, the Deriba Caldera, with two smaller calderas now acting as lakes. One of the lakes is quite deep, while the other is shallow and saline.
The Jebel Marra Volcano receives more annual rainfall than the rest of the surrounding desert, as it is one of the highest regions of the eastern Sahara Desert. Streams radiating out from the lakes of the caldera seem darker in color due to lava flow.
