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.
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 ...
San Andreas Fault System (Banning fault, Mission Creek fault, South Pass fault, San Jacinto fault, Elsinore fault) 1300: California, United States: Dextral strike-slip: Active: 1906 San Francisco (M7.7 to 8.25), 1989 Loma Prieta (M6.9) San Ramón Fault: Chile: Thrust fault: Sawtooth Fault: Idaho, United States: Normal fault: Seattle Fault ...
Fault lines are in black, and red triangles show historically active volcanoes. The Afar triple junction (also called the Afro-Arabian rift system ) is located along a divergent plate boundary dividing the Nubian , Somali , and Arabian plates.
Red Sea Rift between the African (Nubian) Plate and the Arabian plate 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 ...
In the western Mediterranean, the relative motions of the Eurasian and African plates produce a combination of lateral and compressive forces, concentrated in a zone known as the Azores–Gibraltar Fault Zone. Along its northeast margin, the African plate is bounded by the Red Sea Rift where the Arabian plate is moving away from the African plate.
This rifting almost tore apart the African continent but instead formed a complex system of extensional, wrench and pull-apart basins. [ 3 ] [ 4 ] Such basins can be found from Nigeria and Cameroon on the Atlantic, east into Chad and the Central African Republic, through Sudan to Kenya on the Indian Ocean and north of Lake Chad extending into ...
