What kind of fault is Chile located on?

Answer 1

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.
