"Normally new rivers, seas and mountains are born in slow motion. The Afar Triangle near the Horn of Africa is another story. A new ocean is forming there with staggering speed -- at least by geological standards. Africa will eventually lose its horn. Geologist Dereje Ayalew and his colleagues from Addis Ababa University were amazed -- and frightened. They had only just stepped out of their helicopter onto the desert plains of central Ethiopia when the ground began to shake under their feet. The pilot shouted for the scientists to get back to the helicopter. And then it happened: the Earth split open. Crevices began racing toward the researchers like a zipper opening up. After a few seconds, the ground stopped moving, and after they had recovered from their shock, Ayalew and his colleagues realized they had just witnessed history. For the first time ever, human beings were able to witness the first stages in the birth of an ocean..."

And from Scientific American on the same subject, 'Birth of an Ocean.' "... Africa is splitting apart at the seams—literally. 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. Like a shirtsleeve tearing under a bulging bicep, the earth’s crust rips apart as molten rock from deep down pushes up on the solid surface and stretches it thin—sometimes to its breaking point. Each new slit widens as lava fills the gap from below..."
