A magnitude 7.4 earthquake struck western Colombia on Monday, killing at least 132 people and injuring 570 [1, 3].

The disaster highlights the vulnerability of Pacific coast infrastructure to tectonic activity and has triggered an immediate international humanitarian response.

The quake hit at 7:34 local time on Aug. 10 [1, 5]. The epicenter was located in the Chocó department on the Pacific coast, with the tremor originating at a depth of about 100 km [4]. According to the Servicio Geológico Colombiano (SGC), the event was caused by tectonic activity along the country's Pacific subduction zone [1].

Colombian authorities and the Association colombienne des villes capitales reported the casualties [1]. While some early reports indicated lower figures, including 111 deaths and 87 injuries, official counts have risen to at least 132 dead and 570 injured [1, 3].

President Abelardo De La Espriella said many buildings were destroyed across the region [1]. The government has declared a state of emergency to facilitate rescue operations and the delivery of aid [6].

Rescue teams are currently searching through rubble for survivors in the hardest-hit coastal areas. The European Union said it stands with the Colombian people and is providing assistance to the region [6].

Emergency services continue to assess the total number of missing persons as they navigate destroyed roads and collapsed structures. Local officials said the depth of the quake contributed to the wide area of impact, though the most severe destruction remains concentrated in the Chocó department [4].

“A magnitude 7.4 earthquake struck western Colombia on Monday, killing at least 132 people.”

This event underscores the persistent seismic risk facing Colombia's Pacific coast, where the subduction of tectonic plates creates frequent high-magnitude threats. The disparity in early casualty reports suggests significant challenges in communication and data collection in the remote Chocó department, a region that often struggles with infrastructure deficits. The declaration of a state of emergency allows the government to bypass certain bureaucratic hurdles to accelerate reconstruction and international aid integration.
