Geologists believe that a part of the African continent may eventually break off due to the ongoing tectonic activity along the East African Rift System (EARS). This rift is a tectonic plate boundary where the African Plate is splitting into two smaller plates: the Somali Plate and the Nubian Plate. As these plates pull apart, they create a rift valley that is gradually widening.
The process of rifting involves a series of geological activities, including volcanic activity, earthquakes, and the stretching of the Earth's crust. Over millions of years, this rifting can lead to the formation of new ocean basins as the land continues to separate. If the rifting process continues as predicted, it is possible that a segment of the African continent could break away and form a new landmass, potentially leading to the formation of a new ocean.
This geological process is extremely slow, occurring over millions of years, and is still the subject of ongoing research. While predictions about the future of the Earth's geology are speculative, the evidence we see today supports the idea that the East African Rift is a significant and active tectonic feature that will continue to evolve.
