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 .
It is underlain by the Red Sea Rift, which is part of the Great Rift Valley. The Red Sea has a surface area of roughly 438,000 km 2 (169,000 sq mi), [1] is about 2,250 km (1,400 mi) long, and 355 km (221 mi) wide at its widest point. It has an average depth of 490 m (1,610 ft), and in the central Suakin Trough it reaches its maximum depth of ...
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-Tair. The extension rate for this rift varies from about 7 to 17 millimetres per year (0.28 to 0.67 in/year). [6]
Geologists predict that in about 10 million years the whole 6,000 km (3,700 mi) length of the East African Rift will be submerged, forming a new ocean basin as large as today's Red Sea, and separating the Somali plate and the Horn of Africa from the rest of the continent. [9] The floor of the Afar Depression is composed of lava, mostly basalt.
Width and depth are those of the Red Sea Rift, discounting continental shelves < 200 m deep. (These may not be the extremes of the whole rift system.) Length of the Red Sea section 2,250 km (1,400 mi). Canadian Arctic Rift System: 4,800 km (3,000 mi) A northwesterly continuation of the Mid-Atlantic Ridge. West Antarctic Rift System
It represented a continuation of the Red Sea Rift until break-up occurred in the middle Miocene, with most of the displacement on the newly developed Red Sea spreading centre being accommodated by the Dead Sea Transform. During its brief post-rift history, the deepest part of the remnant rift topography has been filled by the sea, creating the ...

"Sea of Calm") is a gulf at the northern end of the Red Sea, to the west of the Sinai Peninsula. Situated to the east of the Sinai Peninsula is the smaller Gulf of Aqaba. The gulf was formed within a relatively young but now inactive Gulf of Suez Rift rift basin, dating back about 26 million years. [1]
