Tristan hotspot

From Wikipedia, the free encyclopedia
The Tristan hotspot is marked 42 on map.

The Tristan hotspot is a volcanic hotspot which is responsible for the volcanic activity which forms the volcanoes in the southern Atlantic Ocean. It is thought to have formed the island of Tristan da Cunha and the Walvis Ridge on the African Plate.[1]

The Gough hotspot is also connected to the Paraná and Etendeka traps by the Walvis Ridge.[2][3]
