About Earthquake Activity in Argentina
Argentina experiences moderate earthquakes in the Andean region, especially near the Chilean border. Learn more about seismic activity in Argentina below.
The largest earthquake recorded in Argentina in the past 100 years was M8.8 in 2010 (2010 Maule, Chile Earthquake). The region is defined by Andean thrust faults, Punta del Este Fault, and the risk level is classified as Moderate (west).
With a population of 46 million, understanding local seismic hazards is crucial. This page provides real‑time USGS data and historical context for Argentina.
Why does Argentina experience earthquakes?
Argentina lies on Nazca Plate subducting beneath South American Plate (west). 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 Argentina Earthquakes
❓ What was the strongest earthquake in Argentina?
The largest earthquake recorded in Argentina in the past 100 years was M8.8 in 2010 (2010 Maule, Chile Earthquake).
❓ Is Argentina on a fault line?
Yes, Argentina is crossed by Andean thrust faults, Punta del Este Fault, making it prone to seismic activity.
❓ How often do earthquakes occur in Argentina?
Due to its tectonic setting (Nazca Plate subducting beneath South American Plate (west)), Argentina experiences hundreds to thousands of earthquakes each year, though most are too small to feel.
❓ What should I do during an earthquake in Argentina?
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.
