What if we stopped Africa from splitting by just... filling the rift with concrete?

Scientists have confirmed that the African continent is slowly splitting apart due to tectonic activity along the East African Rift. The Somali and Nubian plates are drifting away from each other, and eventually this could lead to the formation of a new ocean.

But what if we just... filled the whole rift with concrete?

No new ocean. More land for Africa. Problem solved.
