Q COSTARICA — Tuesday night, a significant earthquake rattled Costa Rica, catching residents by surprise.
The main event, a 6.1 magnitude that shook buildings and sent tremors of up to 20 and 30 seconds in many parts of the country, occurred at 9:57 p.m. Tuesday, according to data from the National Seismological Network (RSN), which located its origin located 25.7 kilometers southwest of Espadilla Sur, in Quepos, Aguirre, Puntarenas, in the Central Pacific, at a depth of 5 kilometers.
According to Mario Protti, a seismologist at Ovsicori, the subsequent seismic activity is within the expected range for an event of this magnitude.
“The largest event in this sequence occurred five minutes after the main event, with a magnitude of 4.1. We will continue to monitor this activity closely and provide timely reports,” Protti explained.
For its part, the National Tsunami Monitoring System (Sinamot) clarified that the earthquake does not pose a tsunami threat to the country.
In Quepos, the seismic event was strong and prolonged. According to Jeudy Mora, deputy mayor of the canton, the Municipal Emergency Committees were immediately activated to respond to reports in the most affected communities.
The National Emergency Commission (CNE) indicated that the earthquake was felt throughout the country, with reports of falling objects in homes and businesses, mainly in Quepos and the Los Santos area. In addition, power outages were reported in areas of Jacó, Parrita, and Quepos.
Authorities remain vigilant for the possibility of more aftershocks in the coming hours.
People reported feeling the ground sway for many seconds, prompting some to rush outside as a precaution.
Costa Rica, sitting on the Pacific Ring of Fire, is no stranger to seismic activity, but this quake was notable for its strength and the suddenness of its arrival.
Authorities quickly assessed the situation, checking for damage and ensuring that critical infrastructure was intact. Early reports indicated minor damages in some areas but no widespread destruction or casualties.
The quake serves as a reminder of the region’s geological volatility and the importance of preparedness.
While Costa Rica has made strides in earthquake readiness, each event reinforces the need for vigilance and community awareness to minimize risks when the earth decides to shake.
