The South American plate is a major tectonic plate which includes the continent of South America as well as a sizable region of the Atlantic Ocean seabed extending eastward to the African plate, with which it forms the southern part of the Mid-Atlantic Ridge.
Scotia plate – Minor oceanic tectonic plate between the Antarctic and South American plates – 1,600,000 km 2 (620,000 sq mi) Somali plate – Minor tectonic plate including the east coast of Africa and the adjoining seabed – 16,700,000 km 2 (6,400,000 sq mi)
The Nazca plate or Nasca plate, [2] 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 Bouvet triple junction is a geologic triple junction of three tectonic plates located on the seafloor of the South Atlantic Ocean. It is named after Bouvet Island, which lies about 250 km (160 mi) to the east. [2] The three plates which meet here are the South American plate, the African plate, and the Antarctic plate.
Huaynaputina (/ ˌ w aɪ n ə p ʊ ˈ t iː n ə / WY-nə-puu-TEE-nə; Spanish: [wajnapuˈtina]) is a volcano in a volcanic high plateau in southern Peru.Lying in the Central Volcanic Zone of the Andes, it was formed by the subduction of the oceanic Nazca Plate under the continental South American Plate.
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.

Here three tectonic plates meet: the South American plate, the Nazca plate and the Antarctic plate. This triple junction is unusual in that it consists of a mid-oceanic ridge, the Chile Rise, being subducted under the South American plate at the Peru–Chile Trench. The Chile triple junction is the boundary between the Chilean Rise and the ...
Plate tectonics within Colombia.. Geology of Colombia refers to the geological composition of the Republic of Colombia that determines its geography.Most of the emerged territory of Colombia covers vast areas within the South American Plate, whereas much submerged territory lies within the Caribbean Plate and the Nazca Plate.
