A 5.4-magnitude earthquake, followed by a strong aftershock, struck the central region of Costa Rica early Monday morning. The tremors caused widespread alarm across the capital city of San José and surrounding areas, though authorities confirm there were no casualties and only minor property damage.
Epicenter and Shallow Depth
According to the National Seismological Network (RSN) at the University of Costa Rica, the initial quake struck at 1:37 AM local time (07:37 GMT).
- Epicenter: Coronado, located northeast of San José.
- Depth: Just 7 km.
- Impact: Due to the extremely shallow depth, seismic waves propagated with high intensity, waking residents across the entire Central Valley region.
Just two minutes later, at 1:39 AM, a 4.8-magnitude aftershock occurred in the same vicinity at a depth of 10 km, further intensifying public concern. Multiple minor aftershocks continued throughout the early morning hours.
Damage Assessment and Expert Analysis
The National Emergency Commission (CNE) reported minor infrastructure damage and localized landslides along a road in the affected region. Emergency services confirmed that no serious injuries or fatalities occurred.
“These are shallow, local fault-line earthquakes, which is why they were felt so strongly by the population. They are sudden and very intense.”

Linkimer reminded the public that Costa Rica remains a highly seismic and vulnerable country, urging citizens to review emergency plans and adhere to official safety guidelines.
