<P> The rift is a narrow zone that is a developing divergent tectonic plate boundary , where the African Plate is in the process of splitting into two tectonic plates , called the Somali Plate and the Nubian Plate , at a rate of 6 -- 7 mm ( 0.24 -- 0.28 in ) annually . As extension continues , lithospheric rupture will occur within 10 million years , the Somali plate will break off , and a new ocean basin will form . </P>
