This Continent Is Splitting and Might Create a New Ocean on Earth

The Earth might be getting a new ocean, though you’ll have to wait a long time to see it.

Due to tectonic plate movement, part of eastern Africa is slowly splitting apart, which could lead to the creation of a sixth ocean in one million to 20 million years. (While a million years is a long time by human life scale, it’s considered to be a small time on a geological scale.)

What is currently the countries of Djibouti, Ethiopia, and Eritrea could be slowly moving away from the rest of the continent, eventually breaking off and allowing water from the Indian Ocean to rush in to fill the gap. This would lead to a separate land mass, new coastlines, and a change in climate patterns and geography for northeast Africa.

This area is part of the East African Rift System (EARS), home to an active continental rift zone, where one plate is slowly pulling away from another one. According to research on the plates, parts of the rift are separating at a rate of .3 inches per year due to the movement of magma deep below the surface. Scientists were alerted to its relatively rapid movement due to a large fissure that appeared in Ethiopia in 2005.

This isn’t, of course, certain but scientific experts believe it’s likely since similar geological activities created the Saudi Arabian peninsula.

“In the future, as extension continues along the rift, the rift valley will sink lower and lower eventually allowing ocean waters to flood into the basin. If rifting continues, new basaltic oceanic crust may form along the centre of the rift producing a new narrow ocean basin with its own mid ocean ridge between the Nubian and Somalian plates,” the London Geographical Society says on its website.

The movement of tectonic plates can be responsible for volcanoes, geysers, and valleys when the plates move apart, and large mountain ranges when they move together, as well as earthquakes. The last new ocean to be identified was the Southern Ocean around Antarctica in 2021.
