About Earthquake Activity in Chile
Chile has produced some of the largest earthquakes ever recorded, including the 1960 Valdivia M9.5. Learn more about seismic activity in Chile below.
The largest earthquake recorded in Chile in the past 100 years was M9.5 in 1960 (1960 Great Chilean Earthquake (Valdivia Earthquake)). The region is defined by Peru-Chile Trench, Liquiñe-Ofqui Fault Zone, and the risk level is classified as Extreme.
With a population of 19 million, understanding local seismic hazards is crucial. This page provides real‑time USGS data and historical context for Chile.
Why does Chile experience earthquakes?
Chile lies on Nazca Plate subducting beneath South American Plate. The movement of these plates builds up stress, which is released as earthquakes. In subduction zones, one plate dives beneath another, generating some of the largest quakes on Earth. In strike‑slip regions like the San Andreas, plates slide past horizontally.

Frequently Asked Questions about Chile Earthquakes
❓ What was the strongest earthquake in Chile?
The largest earthquake recorded in Chile in the past 100 years was M9.5 in 1960 (1960 Great Chilean Earthquake (Valdivia Earthquake)).
❓ Is Chile on a fault line?
Yes, Chile is crossed by Peru-Chile Trench, Liquiñe-Ofqui Fault Zone, making it prone to seismic activity.
❓ How often do earthquakes occur in Chile?
Due to its tectonic setting (Nazca Plate subducting beneath South American Plate), Chile experiences hundreds to thousands of earthquakes each year, though most are too small to feel.
❓ What should I do during an earthquake in Chile?
Drop, cover, and hold on. Stay away from windows, and if outdoors, move to an open area. After the shaking stops, check for injuries and be ready for aftershocks.
