transform boundary
Chile lies on the western edge of the South American plate, close to where it meets the Nazca and Antarctic plates.
Chile is located next to Argentina to the east and the Pacific Plate to the west. This geologic setting makes Chile a seismically active region due to the boundary between the South American Plate and the Nazca Plate to the west.

The Peru-Chile Trench is a convergent plate boundary, where the Nazca Plate is subducting beneath the South American Plate. This subduction zone is associated with frequent earthquakes and volcanic activity.
The plates that collide in Haiti are the Caribbean Plate and the North American Plate. In Chile, the collision is between the South American Plate and the Nazca Plate. These interactions between tectonic plates result in frequent seismic activity in both regions.
the Nazca plate and the South American plate
The boundary off the coast of Chile where the 8.8 earthquake occurred is a convergent boundary, specifically a subduction zone where the Nazca Plate is being pushed beneath the South American Plate. This type of boundary is associated with intense seismic activity and can result in powerful earthquakes.
Chile is located near a special type of thrust fault known as a convergent boundary. Chile is situated on the western coast of the continent of South America, this is the boundary between two tectonic plates, the Nazca plate (which is an oceanic plate) and the South American plate (a continental crustal plate). In this region the Nazca and South American plates are converging at a rate of approximately 80mm / year. The dense oceanic crust of the Nazca plate is being forced under or subducted beneath the less dense continental crust of the South American Plate.
The Chile earthquake in 1960 was caused by the subduction of the Nazca Plate beneath the South American Plate along the Peru-Chile Trench. This subduction zone is known for generating large and powerful earthquakes due to the interaction between these two tectonic plates.
The earthquake in Chile was caused by the Nazca Plate, which is an oceanic tectonic plate, moving beneath the South American Plate, which is a continental plate. The convergence of these two plates resulted in the earthquake.
