According to the latest research conducted on this plate, researchers have confirmed that soon, a piece of East Africa will be separated from the main African continent that will take place in tens of millions of years from now.

Our planet is always changing itself, so a continent that splits into two is not that unusual.

The huge split showed up on March 19 and also gauges greater than 50 feet (15 meters) vast as well as numerous miles along, Face2Face Africa as well as various other information resources reported.

According to geologist David Ahede, what's now happening is the Somali plate moving slowly away from the Nubian plate at a rate of 2.5 centimeters per year. "In the near future if this happens we shall have the Somali plate separating from the other Nubian plate", Kenyan geologist David Ahede tells local media Daily Nation.

The following is an excerpt from Wikipedia on the East African Rift. The EAR began developing around the onset of the Miocene, 22-25 million years ago.[1] In the past, it was considered to be part of a larger Great Rift Valley that extended north to Asia Minor. The East African Rift is an active one, which means that the circulating mantle is the one the movements.

A series of distinct rift basins, the East African Rift System extends over thousands of kilometers.[3] The EAR consists of two main branches. The valley for it stretches from the Gulf of Aden and it divides the African plate into the Nubia plate and the Somali one. When the lithosphere ruptures, a rift valley is formed.

Although most of the time rifting is unnoticeable to us, the formation of new faults, fissures and cracks or renewed movement along old faults as the Nubian and Somali plates continue moving apart can result in earthquakes.

The most recent and accepted view is the theory put forth in 2009: that magmatism and plate tectonics have a feedback with one another, controlled by oblique rifting conditions. Beneath this rift, the rise of a large mantle plume is doming the lithosphere upwards, causing it to weaken as a result of the increase in temperature, undergo stretching and breaking by faulting. This suggests that, in this area, the lithosphere has thinned nearly to the point of complete break up.

When the force is a great one, this could lead to continental rifting. Periods of extension alternated with times of relative inactivity.

The Sun cited Dr Lucia Perez Diaz-Postdoctoral Researcher at the Fault Dynamics Research Group-University of London while explaining the reason of the split that activity along the eastern side of the rift valley became apparent when the large rupture all of a sudden appeared in the South-West of Kenya. These rifts are the result of the actions of numerous normal faults which are typical of all tectonic rift zones.

Towards the Afar region, however, the entire rift valley floor is covered with volcanic rocks.
