convergent boundary
transform boundary
At a convergent boundary between oceanic and continental crust where subduction is occurring.
The largest earthquake recorded was in 1960 in Chile. It was a 9.5.
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.
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 plate boundary the Chile earthquake occurred on in 2010 was the converging boundary. A converging boundary is when two plates move closer together. In this case the converging boundary moved so close together that the plates hut one another. They then subducted under on another and the earthquake was formed.
The earthquake in Chile on February 27, 2010 was caused by the release of stress along the boundary where the Nazca Plate subducts beneath the South American Plate. The sudden movement along this subduction zone generated the earthquake.
The Andes Mountains are the eastern border of Chile.

The Chilean earthquake had a magnitude of 8.8 and was a thrust fault earthquake that occurred at a convergent plate boundary where subduction of the Nazca plate under the South American plate is occurring. This type of thrust faulting at subduction zones is commonly referred to as a megathrust earthquake. Please see the related question for further information.
