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 the Nazca Plate under the South American Plate is largely responsible for the Andean orogeny. The Nazca Plate is bound to the west to the Pacific Plate and to the south with the Antarctic Plate through the East Pacific Rise and the Chile Rise respectively. The movement of the Nazca Plate over several hotspots has created some volcanic islands as well as east-west running seamount chains that subduct under South America. Nazca is a relatively young plate both in terms of age of rocks and existence as an independent plate.

Famous quotes containing the word plate:
“I sometimes have the sense that I live my life as a writer with my nose pressed against the wide, shiny plate glass window of the “mainstream” culture. The world seems full of straight, large-circulation, slick periodicals which wouldn’t think of reviewing my book and bookstores which will never order it.”
—Jan Clausen (b. 1943)
