The African continent is dividing in two, and a new landmass and ocean may form sooner than expected. The change could alter the climate and ecosystem of the region, as well as the way humans live. In the geologic history of Earth, the shifting of lithospheric plates is commonplace, and Africa's impending rift is but another chapter in that story.
In 2005, Ethiopia experienced earthquakes that created a 35-mile-long fissure in the desert. The appearance of this East African Rift marked the visible "start of a long process in which the African plate is splitting into two tectonic plates: the Somali plate and the Nubian plate," said Unilad. Then, in 2018, another crack appeared in Kenya.
The rift has been widening over time, and there has been varying levels of seismic activity along the seam, according to a study published in the journal Frontiers in Earth Science. Still, in the "human life scale, you won't be seeing many changes," Ken Macdonald, a professor at the University of California, Santa Barbara, told the Daily Mail. "You will be feeling earthquakes, you will be seeing volcanoes erupt, but you won't see the ocean intrude in our lifetimes."
The split will change the world's continental makeup. "Somalia, Kenya, Tanzania and some parts of Ethiopia would form a new continent separated by the world's sixth ocean," said Metro. Africa's split "will be just another move in this giant geological playbook," said IFL Science. "Whether we as a species will survive for long enough to witness it? Well, that's a different story." |
