The two tectonic plates beneath the continent of Africa are slowly but surely moving away from each other. The tectonic movement has created a crack in the desert that could house a new ocean in the future. The fissure, located in Ethiopia, has reached lengths of 60 kilometers in recent years and sealed itself with 2.5 cubic kilometers of molten rock, as volcanoes are coming alive and erupt on the surface.
The only eruption of the Dabbahu volcano in recorded history occurred on September 26, 2005. The eruption began 5 kilometers northeast of the summit, while ash from the eruption darkened the area surrounding the volcano for nearly 3 days. It was this eruption that formed the 37 mile long fissure.
The tectonic plates are moving apart at a rate of 2 centimeters each year, so when the fissure completes itself, it will span from from the Red Sea in the north, taking water from the Gulf of Aden, all the way down to the Horn of Africa, separating it from the rest of the continent.
How long will you have to wait until you can dip your toes in this new ocean? We guess that you could make an arrangement in about a million years or so.
