Real-Time Earthquakes in Argentina
Continuous seismic tracking along the Andean Subduction Zone, Precordillera, and San Juan Faults.
Recent Earthquakes in Argentina
LIVELive telemetry feed and seismic report for earthquakes in Argentina.
Active Fault Systems & Tectonic Setting
Geodynamic boundaries, subduction dynamics, and crustal deformation zones.
Argentina's seismic activity is driven by the subduction of the Nazca Plate beneath the South American Plate along the Andes. Central western provinces such as San Juan and Mendoza experience high seismic hazard due to shallow active faulting and deep slab earthquakes.
La Laja Fault (San Juan)
Reverse ThrustActive intraplate reverse fault responsible for the catastrophic 1944 San Juan earthquake.
Precordillera Thrust Belt
Thrust & Fold BeltDense series of east-vergent crustal thrust faults traversing western Mendoza and San Juan.
Sierras Pampeanas Faults
Deep Basement ThrustsLaramide-style reverse fault uplifts in central Argentina producing occasional moderate-to-strong quakes.

La Laja, San Juan Province
January 15, 1944Argentina's worst natural disaster; destroyed 80% of San Juan and initiated the nation's modern seismic building codes.
Caucete, San Juan Province
November 23, 1977Severe crustal thrusting causing extensive soil liquefaction and infrastructure disruption across Caucete.
Pocito, San Juan Province
January 18, 2021Shallow event (depth 20 km) felt strongly across San Juan, Mendoza, Córdoba, and Santiago de Chile.
Frequently Asked Questions
Common questions about seismic activity, safety, and monitoring in Argentina.
Which provinces in Argentina have the highest earthquake risk?▾
San Juan and Mendoza in the Cuyo region experience the highest seismic activity and hazard in Argentina, followed by Salta, Jujuy, and La Rioja along the Andean foothills.
Why do deep earthquakes occur in northwest Argentina?▾
The subducting Nazca Plate dives deeply beneath the Andes into the upper mantle beneath Jujuy and Santiago del Estero, producing deep earthquakes at depths of 500 to 650 kilometers.
What building regulations exist in Argentina for earthquakes?▾
Following the 1944 San Juan earthquake, Argentina created INPRES and enacted the CIRSOC/INPRES-CIRSOC 103 seismic construction regulations, significantly improving structural resilience in Cuyo.
