Chile Rise

The Chile Rise or Chile Ridge is an oceanic ridge, a tectonic divergent plate boundary between the Nazca and Antarctic Plates. Its eastern end is the Chile Triple Junction where the Chile Rise is being subducted below the South American Plate in the Peru–Chile Trench.^[1] It runs westward to a triple point south of the Juan Fernández Microplate where it intersects the East Pacific Rise.
