Earthquakes in Argentina
Argentina's seismic activity is concentrated along its western edge, where the subduction of the Nazca plate beneath the Andes drives earthquakes under the provinces of Mendoza, San Juan and Salta. Much of the eastern country, by contrast, sits on stable craton and rarely shakes.
The most destructive event in the nation's history was the 1944 San Juan earthquake (M7.0), which levelled the city and killed some 10,000 people, prompting sweeping reforms. Beneath the western Andes, unusually deep earthquakes are also recorded as the subducting slab flattens out.
The figures below are drawn live from the EarthquakeIndex archive for the area shown. No one can predict when the next earthquake will strike — but you can follow every event the moment EMSC records it.
