How likely is it that your area will experience an Earthquake?
It is very posible that an earthquake can occur in Peru because Peru is a country located between two plates, the Pacific Plate and the South American Plate. Another reason is that Peru is a country witha high volcanic eruptions and it can produce more earthquakes.
And in South America with have the Nazca Plate, it is a little plate but it can causes big earthquakes.
When these three plates crushes each another it makes that plates move and it causes the esrthquakes.
