The list of earthquakes in Chile shows all relevant earthquakes whose epicenter was in Chile or off its coast.

Records of earthquakes in Chile only begin with the Spanish conquest of the country in the mid-16th century. The first earthquake reported by Spanish chroniclers was the earthquake of October 28, 1562.

Tectonic background

Topographic map of Chile

→ See also: plate tectonics

Chile lies in the so-called Pacific Ring of Fire , a zone of high seismic and volcanic activity that extends around the Pacific Ocean . Strong earthquakes are therefore not uncommon in the coastal regions of Chile, and the country is even one of the areas most severely affected by earthquakes in the Circumpacific region.

Chile lies on the western edge of the South American Plate , on the converging plate boundary to the oceanic Nazca Plate . The two plates move an average of about 63 millimeters towards each other each year, with the Nazca plate being subducted below the continental plate . The tensions that occur in the underground are regularly discharged in earthquakes of different strengths. The worst earthquake ever recorded, the Valdivia earthquake in 1960 , also occurred in Chile.

Due to its location on the Pacific Ocean , severe earthquakes in Chile usually result in a tsunami .
