Astronaut Sergey Ryazansky captured from ISS Tarso Tousside of Tibesti Mountains, Chad.
The Tibesti Mountains lie in the north of Chad, Africa. The highest peak in the range, Emi Koussi (3,445m), is the highest point in both Chad and the Sahara. Major lava flows have formed vast plateaus that overlie Paleozoic sandstone. The volcanic activity was the result of a continental hotspot that arose during the Oligocene and continued in some places until the Holocene. In the image shows Toussidé or Tarso Toussidé (3,265m) which is a potentially active stratovolcano in Chad. The volcano is the source of a number of lava flows, which have flowed westward away from Toussidé and east into the Yirrigué caldera.
The local scenery on the ground is as follows.
