East African rift zones
Rifting began 20 million years ago along the East African rift zones, marked by a 3,700-kilometer line of valleys, volcanoes, and lakes that extends from the tip of the Red Sea to Zimbabwe. If the forces driving this process continue, a new ocean will form and the entire eastern coast of Africa could eventually become a large island.
