The African tectonic plate is huge, covering an area of about 61.7 million square kilometers (23.8 million square miles). This makes it the second-largest tectonic plate on Earth, after the Pacific plate.

It's important to remember that the African plate is not just the continent of Africa – it extends outwards under the Atlantic Ocean and parts of the Indian Ocean. It's a massive chunk of the Earth's crust and upper mantle.
