The East African Rift ( EAR) or East African Rift System ( EARS) is an active continental rift zone in East Africa. The EAR began developing around the onset of the Miocene, 22–25 million years ago. [1] It was formerly considered to be part of a larger Great Rift Valley that extended north to Asia Minor .
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 merging of separate ...
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 ...
The geology of Africa is varied and complex, and gives rise to the wide variety of landscapes found across the continent. The African continent rests over two main plates. The African plate, accounting for the whole of north Africa, and the Somali plate, which accounts for the eastern side of mid and southern Africa. [1]
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 .
The Albertine Rift is the western branch of the East African Rift, covering parts of Uganda, the Democratic Republic of the Congo (DRC), Rwanda, Burundi and Tanzania . It extends from the northern end of Lake Albert to the southern end of Lake Tanganyika . The geographical term includes the valley and the surrounding mountains.
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 ...
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 ...
