The Nazca Plate, named after the Nazca region of southern Peru, is an oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South America. The ongoing subduction along the Peru-Chile Trench of Nazca Plate under the South American Plate is largely responsible for the Andean orogeny. Nazca Plate bound to west to the Pacific Plate and to south with the Antarctic Plate throught the East Pacific Rise and the Chile Rise respectively. The movement of Nazca Plate under several hotpots have created some volcanic island as well as east-west running seamount chains the subduct under South America. Nazca is relatively young plate both in terms of age of rocks and existence as independent plate.
