A M6.2 earthquake struck off the coast of Costa Rica on October 12, 2024, at a depth of 18 km. Moderate shaking was felt by approximately 69,000 people, with an estimated 1.8 million experiencing lighter tremors. No tsunami warning was issued, and the impact is expected to be minimal, although local building vulnerabilities persist.
On October 12, 2024, at 17:43 local time, a significant earthquake measuring M6.2 struck off the coast of Costa Rica, as reported by the United States Geological Survey (USGS). This tremor, noted for its shallow depth of 18 kilometers (approximately 11.2 miles), was confirmed by the European-Mediterranean Seismological Centre (EMSC) as well. The epicenter of the earthquake was strategically located approximately 41.4 kilometers (25.7 miles) northwest of Tamarindo, 67 kilometers (41.6 miles) west-northwest of Santa Cruz, and about 75.9 kilometers (47.1 miles) west of Liberia, in the Guanacaste Province of Costa Rica. According to estimates, around 69,000 individuals perceived moderate shaking, while an additional 1,856,000 experienced light tremors. Fortunately, the event did not pose any threat of a tsunami. The USGS has assigned a Green alert status, indicating a low probability of fatalities and significant economic losses as a result of the earthquake. Although the overall risk is deemed low, it is important to note that the region’s structures are predominantly vulnerable to earthquake damage, especially those constructed with mud and adobe materials. Historically, earthquakes in this vicinity have resulted in additional hazards such as landslides and liquefaction, which could increase potential losses.
The seismic activity off the coast of Costa Rica is part of a larger pattern of tectonic interactions in the region, specifically associated with the subduction of the Cocos Plate beneath the Caribbean Plate. Costa Rica is situated in an area prone to earthquakes due to its geological composition and tectonic movement. Previous earthquakes have led to various secondary hazards, including landslides and liquefaction, significantly affecting communities and infrastructure. Understanding the nature of these seismic events, as well as the vulnerabilities of local construction practices, is critical for assessing risk and preparing for future occurrences.
In summary, the recent M6.2 earthquake off the coast of Costa Rica on October 12, 2024, was a notable event that resulted in moderate shaking felt by approximately 69,000 people, while 1.8 million experienced lighter tremors. The absence of tsunami threats and the low alert status assigned by the USGS indicate a lower risk of casualties. However, the vulnerable nature of many buildings in the region remains a concern, necessitating ongoing evaluation and preparation for future seismic activity.
