Volcanic Fields and Mountains in the Desert of Libya and Chad23.6N 17.8E
The light, yellowish-tan sands covering most of this image belong to the Libyan Desert, one of the most arid places on earth. Although most of the Libyan terrain appears dry, there is a brownish-green non-arid area near the coast.
The brown patch in the midst of the desert at the left edge is the Haruj, a large volcanic field that covers around 45000 km2 in central Libya. It contains about 150 volcanoes, and many craters and lava flows.
In the full image, another brown area can be observed near the bottom. These are the Tibesti Mountains, a volcanic group of inactive volcanoes with one potentially active volcano in the central Sahara desert in the Bourkou-Ennedi-Tibesti Region of northern Chad. The northern slopes extend a short distance into southern Libya.
