Chile back

The Chile Ridge is a mid-ocean ridge in the Pacific off the coast of Chile , with the Nazca Plate in the north and the Antarctic Plate in the south diverging .

In the west, the ridge forms a triple point , with all plate boundaries being divergent plate boundaries . There is the East Pacific Ridge to the north and the Pacific-Antarctic Ridge to the south .

In the east there is also a triple point approximately at the level of the Taitao peninsula , as the Nazca plate, the Antarctic plate and the South American plate meet there. Since the South American plate has a continental crust , both lithospheric plates subduct here. This creates the Atacama Trench .
