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 ...
The East African Rift follows the Red Sea to the end before turning inland into the Ethiopian highlands, dividing the country into two large and adjacent but separate mountainous regions. In Kenya, Uganda, and the fringes of South Sudan, the Great Rift runs along two separate branches that are joined to each other only at their southern end, in ...
When rifting reached the Tanzanian Craton, the rift split into the eastern Gregory Rift and the western Albertine Rift, which are separated by the 1,300 kilometres (810 mi) wide East African Plateau. Large shield volcanoes near the margins of the craton and in the adjacent Mozambique belt issued large volumes of basaltic to trachytic magmatism ...
A massive rift in Ethiopia separated continental plates by 400 feet and is part of a rift network that may flood enough to create a new ocean in 2 million years.
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.
Geologists predict that in about 10 million years the whole 6,000 km (3,700 mi) length of the East African Rift will be submerged, forming a new ocean basin as large as today's Red Sea, and separating the Somali plate and the Horn of Africa from the rest of the continent. [9] The floor of the Afar Depression is composed of lava, mostly basalt.

The Great Rift Valley of Ethiopia, (or Main Ethiopian Rift or Ethiopian Rift Valley) is a branch of the East African Rift that runs through Ethiopia in a southwest direction from the Afar triple junction. In the past, it was seen as part of a "Great Rift Valley" that ran from Mozambique to Syria. Known for its scenery and diverse wildlife in ...
