M6.2 Earthquake Strikes Off Costa Rica’s Coast on October 12, 2024

A strong 6.2 magnitude earthquake struck off the coast of Costa Rica on October 12, 2024, at a depth of 18 kilometers, affecting approximately 1.9 million individuals with varying degrees of shaking. However, there were no tsunami threats or significant casualties reported. The event highlights ongoing seismic risks in the region, particularly regarding the vulnerability of local structures.

On October 12, 2024, a notable earthquake measuring 6.2 on the moment magnitude scale occurred off the coast of Costa Rica at 17:43 local time (11:43 UTC). The earthquake’s depth was recorded at 18 kilometers (11.2 miles) by the United States Geological Survey (USGS), a measurement corroborated by the European-Mediterranean Seismological Centre (EMSC). The epicenter was located 41.4 kilometers (25.7 miles) northwest of Tamarindo, 67 kilometers (41.6 miles) west-northwest of Santa Cruz, and 75.9 kilometers (47.1 miles) west of Liberia, within the Guanacaste Province of Costa Rica. Estimates suggest that approximately 69,000 individuals experienced moderate shaking, while around 1,856,000 felt light tremors. Fortunately, there was no tsunami threat associated with this seismic event. The USGS issued a Green alert, indicating a low probability of fatalities and economic loss resulting from the quake. It is worth noting that the majority of the buildings in this region are constructed from materials that are susceptible to earthquake damage, although some structures are designed to withstand such forces. Historically, recent earthquakes in this area have triggered secondary hazards, such as landslides and soil liquefaction, which may contribute to potential losses in the aftermath of the quake.

Costa Rica is situated in a tectonically active region, making it prone to seismic events. The area is part of the complex boundary between the Caribbean and Cocos tectonic plates. Earthquakes are relatively common, and they pose risks not only due to direct shaking but also through secondary phenomena like landslides or ground failures that can exacerbate damage. Structures in Costa Rica often vary in resilience, with many traditional styles, particularly adobe and mud block constructions, being vulnerable to strong earthquakes. Understanding recent seismic activity helps authorities and communities prepare for future events.

The occurrence of the M6.2 earthquake off the coast of Costa Rica on October 12, 2024, serves as a reminder of the seismic risks faced by the region. While the immediate aftermath reported no tsunami threat and low casualties, the vulnerability of local infrastructure remains a significant concern. Continuous monitoring and the implementation of resilient building practices are crucial in mitigating the impact of future seismic events.
