M6.2 Earthquake Recorded Off the Coast of Costa Rica on October 12, 2024
A magnitude 6.2 earthquake struck off Costa Rica’s coast on October 12, 2024, at a depth of 18 km. Approximately 69,000 people felt moderate shaking, while 1.86 million experienced lighter tremors. No tsunami is anticipated, and damage is expected to be limited, though local buildings remain vulnerable.
On October 12, 2024, at 17:43 local time (11:43 UTC), a strong and shallow earthquake with a magnitude of 6.2 struck off the coast of Costa Rica. The earthquake, as recorded by the United States Geological Survey (USGS), occurred at a depth of 18 kilometers (11.2 miles). Concurrently, the European-Mediterranean Seismological Centre (EMSC) reported the same parameters for this seismic event. The epicenter was identified 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, within Guanacaste Province. It is estimated that approximately 69,000 individuals experienced moderate shaking, while around 1,856,000 felt lighter tremors. Fortunately, seismologists reported no threat of a tsunami following the quake. The USGS has issued a Green alert, indicating a low likelihood of casualties or significant damage from the event. However, there is an acknowledgment that many structures in the region are highly susceptible to earthquake-induced shaking; the most vulnerable buildings typically feature mud walls and adobe block construction. Historical patterns in this area suggest that past seismic eruptions have led to additional hazards, such as landslides and liquefaction, which could potentially exacerbate losses in the event of significant seismic activity, despite the currently expected limited impact.
Costa Rica is situated along the Pacific Ring of Fire, an area with a high frequency of seismic activity due to tectonic plate interactions. The region is prone to earthquakes of various magnitudes that can lead to considerable geological consequences. This particular earthquake underscores the ongoing need for preparedness in vulnerable areas, particularly where infrastructure is not adequately designed to withstand seismic forces. Understanding the building practices of the region is crucial, as several constructions remain at risk during seismic events.
In summary, the M6.2 earthquake off the coast of Costa Rica on October 12, 2024, exemplifies the seismic risks faced by the region. With a depth of only 18 kilometers, the earthquake was felt by nearly two million residents. The situation is closely monitored by seismological organizations, which currently assess a low chance of serious repercussions. Nonetheless, local vulnerabilities, particularly in construction types, may heighten the potential for hazards should future seismic events occur.
