About Earthquake Activity in Costa Rica
Costa Rica experiences very high seismic activity, primarily governed by its tectonic setting: Subduction of the oceanic Cocos Plate beneath the Caribbean Plate along the Middle America Trench at ~85 mm/year, plus Panama Block collision. Historically, the 1991 Limón (Valle de la Estrella) earthquake (M7.7) demonstrated the region's immense seismic hazard potential.Major geological fault structures include Middle America Trench, Central Costa Rica Deformed Belt, Aguacaliente Fault. This page provides continuous, verified seismic telemetry sourced directly from the U.S. Geological Survey (USGS) and the European-Mediterranean Seismological Centre (EMSC).
Earthquakes Today in Costa Rica — Live USGS & EMSC Tracker
Was there an earthquake in Costa Rica today? Yes — in the past 24 hours, our live Today's Earthquakes tracker recorded 8 verified earthquakes in and around Costa Rica. Our real-time seismic monitor detects and maps every tremor instantly using continuous sensor telemetry from the USGS and EMSC. If you just felt shaking and want to confirm it, the interactive map above displays exact epicenter coordinates, focal depth, magnitude, and distance from nearby cities. In the last 30 days alone, Costa Rica recorded 57 earthquakes, with 56 in the past 7 days. With an exposed population of approximately 5.2 million, timely seismic tracking is crucial for emergency awareness.
Why Does Costa Rica Experience Earthquakes?
Seismic activity in Costa Rica is fundamentally driven by its tectonic setting: Subduction of the oceanic Cocos Plate beneath the Caribbean Plate along the Middle America Trench at ~85 mm/year, plus Panama Block collision. As tectonic plates continuously converge, slide past one another, or diverge, frictional forces along fault planes lock the crust until the strain exceeds rock strength. When a fault suddenly slips, stored elastic energy is released as seismic waves that radiate outward, causing the ground motion recorded on seismographs.

Staying Safe During an Earthquake in Costa Rica
If you feel sudden shaking in Costa Rica, remember the official safety protocol: Drop, Cover, and Hold On. Take cover under a sturdy table, shield your head and neck, and hold on until ground shaking completely subsides. Afterwards, check for gas leaks, stay alert for aftershocks, and review our step-by-step earthquake survival guide .
