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 term Great Rift Valley is most often used to refer to the valley of the East African Rift, the divergent plate boundary which extends from the Afar triple junction southward through eastern Africa, and is in the process of splitting the African plate into two new and separate plates.
Plate tectonics map. The East African Rift (Great Rift Valley) in eastern Africa; The Mid-Atlantic Ridge system separates the North American plate and the South American plate in the west from the African plate and the Eurasian plate in the east; The Gakkel Ridge is a slow spreading ridge located in the Arctic Ocean
The Somali Plate is moving away from the African Plate in a split from Djibouti in the north, to Eswatini in the south. [2] The parting of these two plates formed the southern part of what used to be known as The Great Rift Valley. [3] In geological terms, the African and Somali plate separation has formed the East African Rift System (EARS ...
Lake Baikal in Siberia, a World Heritage Site, [3] lies in an active rift valley. Baikal is both the deepest lake in the world and, with 20% of all of the liquid freshwater on earth, has the greatest volume. [4] Lake Tanganyika, second by both measures, is in the Albertine Rift, the westernmost arm of the active East African Rift.
The Azores triple junction is a geologic triple junction where the boundaries of three tectonic plates intersect: the North American plate, the Eurasian plate and the African plate, R-R-R. [9] The Boso triple junction offshore of Japan is a T-T-T triple junction between the Okhotsk microplate, Pacific plate and Philippine Sea plate.
The African continent’s tectonic fate has been studied for several decades, but new satellite measurements are helping scientists better understand the transition and are offering valuable tools ...
East African Rift Valley, Kenya ISS 2012. Lake Turkana, at the northern end of the rift, is 250 kilometres (160 mi) long, between 15 kilometres (9.3 mi) and 30 kilometres (19 mi) wide and is 125 metres (410 ft) at its greatest depth. [13] Most of the other lakes are shallow and poorly drained, and therefore have become alkaline.
