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 ...

Gregory Rift in East Africa. The Gregory Rift (Ufa la Gregori, in Swahili) is the eastern branch of the East African Rift fracture system. The rift is being caused by the separation of the Somali Plate from the Nubian Plate, driven by a thermal plume.
The lakes in this area (e.g. Lake Tanganyika and Lake Rukwa) are located in highly rifted basins and have an inter-fingering relationship with faults. Many of the lakes are bounded by normal or strike-slip faults. [1] The extension rate for this rift starts at about 6 millimetres per year (0.24 in/year) in the north, and declines to the south. [5]
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.
Map of the Dead Sea Transform showing the main fault segments and motion of the Arabian plate relative to the African plate, [1] from GPS data The Dead Sea Transform (DST) fault system, also sometimes referred to as the Dead Sea Rift, is a series of faults that run for about 1,000 km from the Marash triple junction (a junction with the East Anatolian Fault in southeastern Turkey) to the ...
Lake Turkana is an East African Rift feature. [18] A rift is a weak place in the Earth's crust due to the separation of two tectonic plates, often accompanied by a graben, or trough, in which lake water can collect. The rift began when East Africa, impelled by currents in the mantle, [19] began separating from the rest of Africa, moving to the ...
The earthquake occurred in the Mt Rwenzori region, which lies within the Western Rift Valley of the East Africa Rift System, between Lake Edward and Lake Albert. The Mt. Ruwenzori region is the most seismically active region in Uganda and also one of the most seismically active zones in the East Africa Rift System and is bounded by steep active normal faults.
