Main rift faults, plates, plate boundaries, GPS plate velocities between adjacent blocks and minimum horizontal stress directions. 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.

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.
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 .
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 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 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 ...
Map of the Dead Sea Transform showing the main fault segments and motion of the Arabian Plate relative to the African Plate, from GPS data The Dead Sea Transform (DST) fault system, also sometimes referred to as the Dead Sea Rift, is a series of faults that run for about 1,000 km from the Maras Triple Junction (a junction with the East Anatolian Fault in southeastern Turkey) to the northern ...
Þingvallavatn. A rift valley is a linear shaped lowland between several highlands or mountain ranges produced by the action of a geologic rift. Rifts are formed as a result of the pulling apart of the lithosphere due to extensional tectonics. The linear depression may subsequently be further deepened by the forces of erosion.
