The East African Rift system made up the western and eastern continental rifts, and stretches from the Afar region of Ethiopia down to Mozambique. It is an active continental rift that began millions of years ago, splitting at 7mm annually. The regular eruption of volcanoes along the rift and new insights into the break up of continents adds to the belief that the continent may be splitting to form a new ocean.
East Africa is home to several visible geographical wonders that have attracted tourists to the area. These include Lake Malawi and Tanzania’s Lake Tanganyika—respectively, the fourth largest freshwater and the second deepest lakes in the world. It also includes active volcanoes such as the Ol Doinyo Lengai in Tanzania, and the DallaFilla and Erta Ale in Ethiopia.
The Erta Ale stands out as one of the world’s most active volcanoes and one of the only eight and possibly the longest-existing lava lakes in the world.
Though not visible to tourists, among the wonders of the region is the Victoria microplate, one of the largest continental microplates. The Victoria microplate is a rift branch which, along chains of deep lakes and volcanoes, makes up the several features of the East African Rift System.
While this gives researchers new insight into the splitting process of the East Africa Rift system, the “Y” shaped end of the rift at the Afar region is getting more attention, as to where an ocean will likely be formed if the splits continue. The “Y” shaped junction is where the African, Somalian, and Arabian tectonic plates meet near Djibouti and Eritrea and it is associated with active volcanos including the Erta Ale volcano.
However, researchers are uncertain about the future of the East African rift—whether the split will continue and an ocean will eventually be formed. At the rate at which the Afar rift is splitting, it will take tens of million years for an ocean to eventually be formed.
