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 African Plate, also known as the Nubian Plate, is a major tectonic plate that includes much of the continent of Africa (except for its easternmost part) and the adjacent oceanic crust to the west and south. It is bounded by the North American Plate and South American Plate to the west (separated by the Mid-Atlantic Ridge); the Arabian Plate ...
The Great Rift Valley (Swahili: Bonde la ufa) is a series of contiguous geographic depressions, approximately 6000 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. [1][2] While the name ...
The East African Rift, where three plates are pulling away from one another: the Arabian Plate and two parts of the African Plate—the Nubian and Somali—which eventually led to the formation of the Lwandle plate as well as other microplates. The Afar Triangle, shaded at the center, is a triple junction that separates the three plates. [6]
Red Sea Rift. 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 Afar Depression of the Horn of 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.

At zones of continent-to-continent rifting, divergent boundaries may cause new ocean basin to form as the continent splits, spreads, the central rift collapses, and ocean fills the basin, e.g., the East African Rift, the Baikal Rift, the West Antarctic Rift, the Rio Grande Rift. Convergent boundary
The African continent’s tectonic fate has been studied for several decades, but new satellite measurements are helping scientists better understand the transition and are offering valuable tools ...
