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 ...
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 forms of the zones with lower Vs (colors toward red) suggest the hotter structures in the Mantle. The distinguishing fourth map depicts a depth below the 410 km discontinuity where Vs steeps up (getting overall bluer) but still displays the signature of a plume at the substrate of the East African Rift.
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.

Manda-Hararo rift in the Afar region of Ethiopia with Dabbahu Volcano in the background. The Red Sea Rift is between the African (or Nubian) and Arabian plates. The rift runs along the length of the Red Sea, starting from the Dead Sea to the Afar triple junction. Within the rift, in the Red Sea, there are many volcanoes, including the Jabal al ...
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.
East African Rift Valley, Kenya ISS 2012. Lake Turkana, at the northern end of the rift, is 250 kilometres (160 mi) long, between 15 kilometres (9.3 mi) and 30 kilometres (19 mi) wide and is 125 metres (410 ft) at its greatest depth. [13] Most of the other lakes are shallow and poorly drained, and therefore have become alkaline.
