Explain why the area near nazca and south american plate boundary gets a lot of earthquakes

Hello There!!

Explanation:

Crustal earthquakes are caused by deformation and mountain building in the overriding South America plate and generate earthquakes as deep as approximately 50 km. Interplate earthquakes occur due to slip along the dipping interface between the Nazca and the South America plates.A subduction zone has been formed, thus an oceanic trench with it, where the Nazca plate subducts below the South American plate. An orogeny occurred, which resulted in the formation of the Andean mountain range in the along the western coastline of South America.

hope this helps,have a great day!!
