Note that the splitting of this eastern part of Africa from the rest of the continent is due the fact that the Africa Plate, a tectonic plate, is in the process of splitting into two new plates. The two new plates have been dubbed the Somali Plate (bottom-right side) and the Nubian Plate (left side).
What evidence is there that the continent of Africa may be splitting apart?
Last month, the crack, 50 feet wide and 50 feet deep in some places, appeared in Kenya. Geologists say the several-miles-long crack is evidence that the continent could eventually split in two.
Where is Africa breaking apart?
The African continent is slowly separating into several large and small tectonic blocks along the diverging East African Rift System, continuing to Madagascar — the long island just off the coast of Southeast Africa — that itself will also break apart into smaller islands.
Why did Pangea break up?
During the Triassic Period, the immense Pangea landmass began breaking apart as a result of continental rifting. A rift zone running the width of the supercontinent began to open up an ocean that would eventually separate the landmass into two enormous continents.
