A Continent Dividing: Scientists Confirm a New Ocean is Forming in Africa

The image is a scientific visualization showing how Africa could look in about 10 million years as a result of a slow but powerful geological process that is gradually splitting the continent in two.

This transformation is being driven by the East African Rift System, a vast 3,500-kilometer-long fracture in the Earth’s crust that stretches across eastern Africa. Over time, the African tectonic plate is slowly breaking apart into two separate plates.

The larger western section is known as the Nubian Plate, which will continue to form most of the African mainland. The eastern portion, called the Somali Plate, includes countries such as Somalia, Kenya, Tanzania, and parts of Ethiopia. This section is expected to slowly drift away and eventually form a new island continent.

Although the movement is extremely slow—only a few millimeters per year—it is expected to lead to major changes over millions of years. One of the most significant outcomes will be the formation of a new ocean. As the rift widens, waters from the Red Sea and the Gulf of Aden are expected to flow into the gap, gradually creating a new ocean basin that could become Earth’s sixth ocean.

The shifting landscape will also reshape Africa’s geography. Countries that are currently landlocked, such as Uganda, Rwanda, Burundi, and Zambia, could eventually gain coastlines as new seas form within the continent.

Recent scientific studies suggest that parts of the Earth’s crust within the rift—especially in areas like the Turkana Rift—have thinned significantly, indicating that the separation process may already be irreversible.

While dramatic surface cracks can sometimes appear suddenly, such as the large fissure that opened in Ethiopia in 2005, the full breakup of the continent is an extremely slow process that will take millions of years to complete.
