M6.2 Earthquake Strikes Off the Coast of Costa Rica: Overview and Implications

On October 12, 2024, a magnitude 6.2 earthquake struck off Costa Rica’s coast at a depth of 18 km. The epicenter was near Tamarindo, with moderate shaking affecting an estimated 69,000 people. Fortunately, no tsunami threat has been reported, and the USGS has assessed a low likelihood of casualties or damage.

A significant and shallow earthquake, classified by the United States Geological Survey (USGS) as a magnitude 6.2, struck off the coast of Costa Rica on October 12, 2024, at 17:43 local time (11:43 UTC). The earthquake occurred at a depth of 18 kilometers (approximately 11.2 miles). The European-Mediterranean Seismological Centre (EMSC) reported the same magnitude and depth. The 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, located in Guanacaste Province. It is estimated that around 69,000 individuals experienced moderate shaking, while approximately 1,856,000 felt light shaking. Fortunately, there has been no tsunami threat associated with this seismic event.

Costa Rica is known for its seismic activity due to its location along the Pacific Ring of Fire. Earthquakes are a common occurrence in this region, and various geological factors contribute to the vulnerabilities of the local infrastructure. Recent seismic events have historically resulted in secondary hazards such as landslides and liquefaction, which can exacerbate the impacts of the shaking. The construction quality and types of buildings prevalent in the area also play significant roles in how populations are affected by earthquakes. The USGS issued a Green alert regarding the shaking-related fatalities and economic losses, indicating a low probability of severe casualties or damage, despite the area’s buildings primarily being made of mud walls and adobe blocks, which are susceptible to earthquake impact.

In summary, the earthquake measuring 6.2 in magnitude that struck off Costa Rica on October 12, 2024, was significant, yet no substantial threats, such as tsunamis, emerged as a result. The community faces inherent vulnerabilities due to the common building practices in the region, yet the reported casualties and damages are expected to be minimal. Continued vigilance and preparedness are essential in this seismically active area.
