Map showing the location of Nazca Ridge off the west coast of Peru. The Nazca Ridge is a submarine ridge, located on the Nazca plate off the west coast of South America.This plate and ridge are currently subducting under the South American plate at a convergent boundary known as the Peru-Chile Trench at approximately 7.7 cm (3.0 in) per year.

Challenger 17. Eltanin 18. Udintsev 19. East Pacific Rise (S-shaped) 20. Nazca Ridge . Most fracture zones in the Pacific Ocean originate from large mid-ocean ridges (also called "rises") such as the East Pacific Rise, Chile Rise and Juan de Fuca Ridge. The plates that host the fractures are Nazca, Pacific, Antarctic, Juan de Fuca and Cocos ...
The Carnegie Ridge is a 1,350-kilometre-long (840 mi) and up to 300-kilometre-wide (190 mi) feature on the ocean floor of the northern Nazca plate that includes the Galápagos archipelago at its western end. It is being subducted under South America with the rest of the Nazca plate.
The team discovered the mountain along the Nazca Ridge, which is located about 900 miles west of the Chilean coast—a region that itself contains a chain of underwater mountains. But this ...
Bathymetric map of area around the Galápagos microplate with main tectonic features marked. The 13,000 km 2 Galápagos microplate lies at the western end of the GSC. It is bounded to the west by strands of the East Pacific Rise, to the southeast by the Dietz Volcanic Ridge and the Dietz Deep rift, and to the north by the GSC. [4]
The Falkor sails around the world, gathering data to create a detailed map of the sea floor. Previous expeditions to the Salas y Gómez and Nazca Ridges in January and February documented over 150 ...
The trench is also a part of the Chile triple junction, an unusual junction that consists of a mid-oceanic ridge and the Chile Rise being subducted under the South American plate at the Peru–Chile Trench. Two seamount ridges within the Nazca plate enter the subduction zone along this trench: the Nazca Ridge and the Juan Fernández Ridge.
A team of oceanographers led by Schmidt Ocean Institute have discovered and mapped a new seamount on the Nazca Ridge 900 miles off the coast of Chile.
