M6.2 Earthquake Strikes Off the Coast of Costa Rica

A 6.2 magnitude earthquake struck offshore Costa Rica on October 12, 2024, at a depth of 18 kilometers, with a Green alert indicating low likelihood of fatalities or significant damages. Approximately 69,000 people experienced moderate shaking, while 1.86 million felt light tremors. No tsunami threat has been reported, but the area’s infrastructure is vulnerable to seismic activity.

On October 12, 2024, at 17:43 local time, a significant earthquake measuring 6.2 on the Richter scale struck offshore, approximately 41.4 kilometers (25.7 miles) northwest of Tamarindo, Costa Rica. The earthquake was recorded at a depth of 18 kilometers (11.2 miles) according to the United States Geological Survey (USGS), with the European-Mediterranean Seismological Centre (EMSC) confirming the same magnitude and depth. The populations of neighboring towns, including Santa Cruz and Liberia, experienced varying degrees of shaking, with an estimated 69,000 individuals encountering moderate tremors and approximately 1,856,000 experiencing light shaking. Despite these effects, no tsunami warning was issued in relation to this seismic event. The USGS provided a Green alert, indicating a low likelihood of fatalities and economic damages arising from this earthquake. Nevertheless, it is important to note that the region’s infrastructure is largely composed of structures vulnerable to seismic activity, predominantly featuring mud walls and adobe blocks. While there have been instances of secondary hazards like landslides and soil liquefaction from previous seismic events in this area, the likelihood of significant damage remains understated due to the preparedness of some resistant structures.

Earthquakes are a common natural phenomenon, particularly in regions situated along tectonic plate boundaries. Costa Rica, located in a seismically active zone, often experiences such geological events. The recent earthquake underscores the importance of understanding seismic risks, especially as many buildings in the area may not be designed to withstand significant shaking. The interaction between tectonic plates, coupled with the geological characteristics of the region, frequently results in both minor and severe tremors, making earthquake preparedness essential for the local population. Additionally, awareness of the potential for secondary hazards following an earthquake is critical for mitigating risks and enhancing community resilience.

In summary, the recent M6.2 earthquake off the coast of Costa Rica serves as a reminder of the seismic activity prevalent in the region. While the immediate consequences reported indicate a low likelihood of casualties and significant damage, it is crucial for communities to remain vigilant and prepared for future seismic events. The structural vulnerabilities present in many buildings accentuate the need for ongoing awareness and construction improvements in order to effectively mitigate risks associated with earthquakes.
