How fast is the East African rift rifting?

How fast is Africa splitting apart?

The three plates are separating at different speeds. The Arabian plate is moving away from Africa at a rate of about 1 inch per year, while the two African plates are separating even slower, between half an inch to 0.2 inches per year, according to Macdonald.

How fast is the East African Rift moving?

As a result, the African plate is fragmenting into two, with the constituent Somali and Nubian plates moving away from each other at the normally negligible rate of 1.9-6.9 millimeters per year. The first of the fractures that make up the rift arose in the Afar region of Ethiopia around 30 million years ago.

Is Africa breaking apart?

Summary: The African continent is slowly separating into several large and small tectonic blocks along the diverging East African Rift System, continuing to Madagascar – the long island just off the coast of Southeast Africa – that itself will also break apart into smaller islands.

What is the most important feature of the Great Rift Valley in East Africa?

The Gregory Rift stretches from the Red Sea and the Arabian Sea to as far south as Mount Kilimanjaro. One of the most important features of the Gregory Rift is the Afar Triple Junction, found where the Horn of Africa straddles the Red Sea and the Gulf of Aden in the Arabian Sea.

Is Israel on the African tectonic plate?

Israel is situated along the border between the African Tectonic Plate and the Arabian Tectonic Plate. The border between these two plates forms part of the Great Rift Valley, the world’s most extensive geological fault, which extends southward through eastern Africa as far south as Mozambique.

Which countries does the Rift Valley pass through?

The Rift Valley consists of a group of independent interior basins, extending from Djibouti in the north to Tanzania in the south, nearly half being located in Ethiopia.

Name of basin Total area of basin Area in the country
Uganda 4 514
Kenya 102 452
Southern lakes: 178 800
Kenya 25 000

What direction is the African plate moving?

For millions of years the African plate, which contains part of the Mediterranean seabed, has been moving northward toward the Eurasian Plate at a rate of about an inch every 2.5 years (a centimeter a year).

Does the Red Sea have thick or thin plates?

The crust thins to about 23 km along the Red Sea coast and to about 25 km along the Gulf of Aqaba. We observed a dramatic change in crustal thickness between the topographic escarpment of the Arabian shield and the shorelines of the Red Sea.
