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 system plays a key role in Tanzania's current day structural geology. Graben rift valleys often have volcanism associated with them. The Western Rift is filled with Lake Tanganyika and Lake Nyasa, while the section from Lake Natron to Lake Nyasa is part of the Eastern Rift (also known as the Gregory Rift).
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.

A simplified geologic map of the Afar Depression. The Afar Depression is the product of a tectonic triple-rifts junction (the Afar triple junction), where the spreading ridges forming the Red Sea and the Gulf of Aden emerge on land and meet the East African Rift. The conjunction of these three plates of Earth's crust is near Lake Abbe.
More recently, as East Africa begins to split from the rest of the continent, the two arms of the East African Rift System have developed on either side of the country. The western arm of the rift system runs through western Uganda, where it is known as the Albertine Rift , whilst the eastern arm runs immediately east of its border with Kenya ...

Evidence shows the East African Rift System is a typical complex continental-continental rifting event beginning in the Paleogene. It was caused by the far-field stress from the subduction of the Arabian plate under the Eurasian plate, and by mantle upwelling powered by multiple hot spots around the EARS.
Researchers' new insight into the splitting process of the East Africa Rift systems show where an ocean will likely be formed if the continent's split continues.
