The Red Sea Rift is a mid-ocean ridge between two tectonic plates, the African plate and the Arabian plate. It extends from the Dead Sea Transform fault system, and ends at an intersection with the Aden Ridge and the East African Rift , forming the Afar triple junction in the Afar Depression of the Horn of Africa .
The Red Sea was formed by the Arabian Peninsula being split from the Horn of Africa by movement of the Red Sea Rift. This split started in the Eocene and accelerated during the Oligocene . The sea is still widening (in 2005, following a three-week period of tectonic activity it had grown by 8 m [26 ft]), [ 36 ] and it is considered that it will ...
Along its northeast margin, the African plate is bounded by the Red Sea Rift where the Arabian plate is moving away from the African plate. The New England hotspot in the Atlantic Ocean has probably created a short line of mid- to late-Tertiary age seamounts on the African plate but appears to be currently inactive. [5]
The rifting of Gondwana occurred from 190 Ma to 47 Ma separating Madagascar from the eastern coast of Africa and placing the Seychelles/Mascarene Plateau northeast of Madagascar. [ 4 ] [ 5 ] The rifting of the Red Sea started around 30 million years ago and the first rifting occurred in the northern West African Rift System around 20 million ...
Manda-Hararo rift in the Afar region of Ethiopia with Dabbahu Volcano in the background. The Red Sea Rift is between the African (or Nubian) and Arabian plates. The rift runs along the length of the Red Sea, starting from the Dead Sea to the Afar triple junction. Within the rift, in the Red Sea, there are many volcanoes, including the Jabal al ...
Rifting began along the whole of the Red Sea -Gulf of Suez rift system during the Late Oligocene. In the Gulf of Suez rift, the rifting culminated during the Burdigalian stage (late Early Miocene, c. 18 Ma). In the Middle Miocene break-up occurred along the whole length of the Red Sea rift with seafloor spreading beginning in the Late Miocene.
The gulf was formed within a relatively young but now inactive Gulf of Suez Rift rift basin, dating back about 26 million years. [1] It stretches some 300 kilometres (190 mi) north by northwest, terminating at the Egyptian city of Suez and the entrance to the Suez Canal. Along the mid-line of the gulf is the boundary between Africa and Asia. [2]
The Great Rift Valley (Swahili: Bonde la ufa) is a series of contiguous geographic depressions, approximately 6,000 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.
