Answer:
South America is a southern continent that composes the South American plate. The South American plate and the Nazca plate shares a convergent plate boundary, forming a subduction zone and is marked by the Peru-Chile trench. The Nazca plate is moving currently at a speed of approximately 8 cm/year, which is much faster. Due to this constant collision between the plates, the western part of South America is extensively affected that eventually gave rise to the formation of the San Andes mountains. A large number of earthquakes occurs in this region of varying magnitude, causes much destruction in those places.
In addition to this, this country is also located near to the Ring of Fire, which is the region of active tectonism, as a result of which numerous earthquakes occur.
Thus, South America is one of the location on earth that is prone to high seismic activity.
