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 is a continental rift extending from eastern to southern Africa over a length of 4,000 kilometres (2,500 mi), [20] where there is high heat flow through a thinner crust. [21] In the Gregory Rift, spreading began about 1.2 million years ago [ 20 ] and is ongoing at a rate of about 3 millimetres per year (0.12 in/year). [ 22 ]
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 Afar Triangle (also called the Afar Depression) is a geological depression caused by the Afar Triple Junction, which is part of the Great Rift Valley in East Africa. The region has disclosed fossil specimens of the very earliest hominins; that is, the earliest of the human clade, and it is thought by some paleontologists to be the cradle of ...
Ol Doinyo Eburru is an active complex of volcanoes in the Great Rift Valley, Kenya to the northwest of Lake Naivasha. [2] It is being exploited for geothermal energy. [3] Soysambu Conservancy is located to the north of the massif, between Lake Elmenteita to the east and Lake Nakuru to the west. [4]
In one of the hottest places on Earth, along an arid stretch of East Africa’s Afar region, it’s possible to stand on the exact spot where, deep underground, the continent is splitting apart.
Menengai Crater is a massive shield volcano with one of the biggest calderas in the world, in the Great Rift Valley, Kenya. It is the largest volcano caldera in Kenya and the second largest volcano caldera in Africa. [1] Volcanic formed rich loam soils enrich the adjacent farmland around its flanks. The crater is on the floor of the Rift Valley.
The Great Rift Valley is part of an intra-continental ridge system that runs through Kenya from north to south. It is part of the Gregory Rift, the eastern branch of the East African Rift, which starts in Tanzania to the south and continues northward into Ethiopia. [1] It was formed on the "Kenyan Dome" a geographical upwelling created by the ...
