PRISMA captures the oasis of the Libyan desert

23 May 2022

In these images produced starting from the L2D data of the hyperspectral satellite PRISMA we can observe the volcano and the oasis of Waw an Namous, in the region of Fezzan, Libya.

Formed relatively recently, the caldera and the surrounding area are characterized by a much darker color than the sand of the Sahara, as evident both from the false color image (RGB) on the left and in an infrared band on the right).

The caldera has several lakes of both fresh and salt water, and therefore provides sustenance for vegetation, insects and birds, including migratory species. Given the scarcity of rainfall in the area, these lakes are believed to be fed by underground springs.
