Africa is splitting apart at the seams. From the southern tip of the Red Sea southward through Eritrea, Ethiopia, Kenya, Tanzania, and Mozambique, the continent is coming unstitched along a zone called the East African Rift."
This stretching of the earth's crust has been going on for 20 million years, and within another 10 million the Red Sea will have broken through to create a new sea.
