A map of East Africa showing some of the historically active volcanoes (as red triangles) and the Afar Triangle (shaded at the center), which is a so-called triple junction (or triple point) where three plates are pulling away from one another: the Arabian plate and two parts of the African plate—the Nubian and Somali—splitting along the East African Rift Zone Main rift faults, plates ...
Plate tectonics map. The East African Rift (Great Rift Valley) in eastern Africa; The Mid-Atlantic Ridge system separates the North American plate and the South American plate in the west from the African plate and the Eurasian plate in the east; The Gakkel Ridge is a slow spreading ridge located in the Arctic Ocean
This rift zone separates the African plate to the west from the Somali plate to the east. One hypothesis proposes a mantle plume rising beneath the Afar region pushing the crust outward, whereas an opposing hypothesis explains the rifting by dynamics in the crust, as a break in the African plate along a line of maximum weakness as plates to its ...
Millions of years from now, northern Africa could be home to a new ocean, as tectonic plates pull apart along the East African Rift System, according to scientists. Experts have long known that ...
Map of the Great Rift Valley. The Great Rift Valley (Swahili: Bonde la ufa) is a series of contiguous geographic depressions, approximately 6,000 or 7,000 kilometres (4,300 mi) in total length, the definition varying between sources, that runs from the southern Turkish Hatay Province in Asia, through the Red Sea, to Mozambique in Southeast Africa.
The parting of these two plates formed the southern part of what used to be known as The Great Rift Valley. [3] In geological terms, the African and Somali plate separation has formed the East African Rift System (EARS), comprising two separate rifts systems - the Eastern Rift Valley, [4] and a western branch known as the Albertine Rift.

Red Sea Rift between the African (Nubian) Plate and the Arabian plate. The Red Sea Rift is a mid-ocean ridge between two tectonic plates, the African plate and the Arabian plate. It extends from the Dead Sea Transform fault system, and ends at an intersection with the Aden Ridge and the East African Rift, forming the Afar triple junction in the ...
The triple junction is at , inside the Afar Triangle (at center shadedFault lines are in black, and red triangles show historically active volcanoes. The Afar triple junction (also called the Afro-Arabian rift system) is located along a divergent plate boundary dividing the Nubian, Somali, and Arabian plates.
