The west coast of south america, where many earthquakes occur, is which type of plate boundary?

Convergent boundary

Explanation:

It is easy to compare the relationship that exist between earthquakes and boundaries. Through the divergent boundaries, earthquakes are usually common but are restricted to a small zone that lies close to the ridge and less than 30 km in depth. Shallow earthquakes are commonly experienced in many parts of the country.

However, in places that they are common, earthquakes are abundant and they happen to be deep on the subduction as well as the landside where they cause major destruction when they occur.
