The African superswell is an extraordinary uplift of the African continent, particularly its southern half; southern Africa on average lies a full kilometer above sea level, with seemingly anomalous uplifts extending well into the south Atlantic ocean.
The superswell is a relatively recent phenomenon, probably beginning between 5 and 30 million years ago. A proposed cause of the superswell is isostatic and dynamic topography caused by a mantle plume, though this hypothesis is controversial and the origin of the superswell remains an active area of research.
