M6.2 Earthquake Off Costa Rica: Impacts and Insights

A 6.2 magnitude earthquake struck off the coast of Costa Rica on October 12, 2024, at a depth of 18 km. An estimated 69,000 people felt moderate shaking, while 1,856,000 experienced light tremors. No tsunami threat was reported, and the USGS indicated a low likelihood of casualties and damage, despite the vulnerability of local structures.

A powerful earthquake with a magnitude of 6.2 struck off the coast of Costa Rica on October 12, 2024, at 17:43 local time (11:43 UTC), as recorded by the United States Geological Survey (USGS). The quake occurred at a shallow depth of 18 kilometers (11.2 miles). The reported epicenter was situated approximately 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 in Guanacaste Province. The earthquake was felt by an estimated 69,000 individuals who experienced moderate shaking, while about 1,856,000 residents felt light tremors. Fortunately, no tsunami threat has been associated with this seismic event. The USGS issued a Green alert, indicating a low probability of casualties and economic damage from the tremor. However, the vulnerability of the local infrastructure, primarily characterized by mud wall and adobe constructions, remains a concern in such seismic zones. This earthquake follows a trend in the region, where prior seismic activities have sometimes led to secondary issues such as landslides and soil liquefaction.

Earthquakes in Costa Rica and surrounding regions are relatively common due to the tectonic activity in Central America, where the Cocos Plate subducts beneath the Caribbean Plate. The country is known for its extensive earthquake risk, which is heightened by vulnerable building practices in many local communities. Seismologists monitor such activities closely to assess risks and prepare for potential impacts on populations and infrastructure. The recent earthquake’s shallow depth meant that it could be felt over a wide area, emphasizing the need for public awareness and preparedness in seismic regions.

The recent M6.2 earthquake off the coast of Costa Rica serves as a reminder of the seismic risks faced by the region. While the immediate impacts appear to be limited, the existing vulnerability of structures in the area necessitates ongoing vigilance and preparedness for future seismic events. Effective response strategies, awareness campaigns, and building standards are vital to minimize the risks associated with such earthquakes.
