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 ...
Great Rift Valley. The Great Rift Valley ( Swahili: Bonde la ufa) is a series of contiguous geographic trenches, approximately 7,000 kilometres (4,300 mi) in total length, that runs from Lebanon in Asia to Mozambique in Southeast Africa. [1] While the name continues in some usages, it is rarely used in geology as it is considered an imprecise ...
East Africa, also known as Eastern Africa or the East of Africa, is a region at the eastern edge of the African continent, distinguished by its geographical, historical, and cultural landscape. Defined in varying scopes, the region is recognized in the United Nations Statistics Division scheme as encompassing 18 sovereign states and 4 territories.
The East African Plateau is a large plateau in the eastern part of central Africa in Uganda, Kenya and Tanzania. Its elevation is mostly between 1000 and 1500 meters. It is subdivided into a number of zones running north and south and consisting in turn of mountain ranges, tablelands, and rift valleys. The most striking feature is the existence ...
The East African Rift System (EARS) is the world’s largest continental rift, stretching from Jordan to Mozambique. For years, geologists have been puzzled as to why EARS displays some ...
Great Rift Valley, Ethiopia. The Great Rift Valley of Ethiopia, (or Main Ethiopian Rift or Ethiopian Rift Valley) is a branch of the East African Rift that runs through Ethiopia in a southwest direction from the Afar Triple Junction. In the past, it was seen as part of a "Great Rift Valley" that ran from Mozambique to Syria .
Afar Triple Junction. The triple junction is at 11°30′N 43°00′E, inside the Afar Triangle (at center shaded red). 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 ...
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 Valley, the West Antarctic Rift, the Rio Grande Rift. Convergent boundary
