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 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 ...
Geology of Africa. 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]
Afar Triple Junction. Coordinates: 11°30′N 43°00′E. 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 ...
A rift is a weak place in Earth's crust due to the separation of two tectonic plates, often accompanied by a graben, or trough, in which lake water can collect. This rift began when East Africa, impelled by currents in the mantle, began separating from the rest of Africa, moving to the northeast. The basins that resulted from the geological ...
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 ...
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.
The East African Rift system plays a key role in Tanzania's current day structural geology. Graben rift valleys often have volcanism associated with them. The Western Rift is filled with Lake Tanganyika and Lake Nyasa, while the section from Lake Natron to Lake Nyasa is part of the Eastern Rift (also known as the Gregory Rift). Lake Rukwa and ...
