More than 4,000 km long, the Great Rift Valley tectonic fault, which includes the West and East Great Rift valleys, crosses eastern Africa from the Red Sea to the mouth of the Zambezi River. It results from the gradual separation of the Somalian lithospheric plate. This process is just beginning: in several million years, East Africa will detach itself to become an independent continent. The intense volcanic activity in the region has led to the formation of the highest mountains in Africa, such as Mount Kilimanjaro and Mount Kenya.The largest lakes in Africa (Victoria, Tanganyika, Malawi), tectonic in origin, are also situated along the Great Rift Valley. Paleontologists think that the Great Rift region was the birthplace of the first human beings, more than 2 million years ago.
