The formation of the Rift Valley continues, probably driven by [[mantle plume]]s and ultimately a result of the [[African superswell]]. The associated geothermal activity and spreading at the rift has caused the [[lithosphere]] to thin from a typical 100 km thickness for continents to a mere 20 km. Though it is common for one arm of a triple junction to fail, if spreading continues the lithosphere may rupture several million years hence, splitting eastern Africa off to form a new landmass. In short, this will lead to the formation of a new [[mid-ocean ridge]].

The volcanic activity at this site and unusual concentration of [[hotspot (geology)|hotspots]] has produced the volcanic mountains [[Mount Kilimanjaro]], [[Mount Kenya]], [[Mount Karisimbi]], [[Mount Nyiragongo]], [[Mount Meru, Tanzania|Mount Meru]] and [[Mount Elgon]] as well as the [[Crater Highlands]] in [[Tanzania]]. The [[Ol Doinyo Lengai]] [[volcano]] remains active, and is currently the only [[carbonatite|natrocarbonatite]] volcano in the world.

 

The Rift Valley has been a rich source of fossils that allow study of [[human evolution]], especially in an area known as Piedmont. Because the rapidly eroding highlands have filled the valley with sediments, a favourable environment for the preservation of remains has been created. The bones of several [[Hominidae|hominid]] ancestors of modern humans have been found there, including those of "[[Australopithecus afarensis|Lucy]]", a nearly complete [[australopithecine]] skeleton, which was discovered by anthropologist [[Donald Johanson]]. [[Richard Leakey|Richard]] and [[Mary Leakey]] have also done significant work in this region.
