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 ...
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 triple junction is at , inside the Afar Triangle (at center shadedFault 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.
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 ...
The Midcontinent Rift System in North America is marked by a series of horsts extending from Lake Superior to Kansas. [ 12 ] The Rwenzori Mountains in the East African Rift are an upthrown fault block, and are the highest non-volcanic, non-orogenic mountains in the world.
A geological anomaly along the The East African Rift System has long stumped scientists—until now. A New Discovery May Help Predict When Africa Will Ultimately Split in Two Skip to main content
The East African Rift, for example, forms a triple junction with the Red Sea and the Gulf of Aden, both of which have progressed to the seafloor spreading stage. Likewise, the Mid-American Rift constitutes two arms of a triple junction along with a third which separated the Amazonian Craton from Laurentia around 1.1 Ga .
Researchers' new insight into the splitting process of the East Africa Rift systems show where an ocean will likely be formed if the continent's split continues.
