A magnitude-7.4 earthquake struck Colombia on Monday, killing 111 people and collapsing dozens of buildings [1, 5].

The disaster has triggered a massive humanitarian response as rescue teams scramble to locate survivors trapped under rubble in several affected regions.

The quake hit at 7:34 a.m. local time on Aug. 10 [7]. The epicenter was located near San José del Palmar in the Chocó department [6]. Seismologists said the quake occurred at a depth of approximately 100 km [9].

Official reports confirm 111 deaths [1, 2]. The number of injured remains uncertain; reports range from 87 [3] to more than 100 people [4]. Emergency responders have identified 61 collapsed buildings [8].

The impact of the seismic event extended beyond Colombian borders. The tremor was felt in Panama, Venezuela, and Quito, Ecuador [10, 11].

Rescue operations are currently focused on the Chocó department and surrounding areas. Teams are using heavy machinery and search dogs to navigate the debris of the 61 collapsed structures [8].

"Suman hasta el momento 111 muertos," a Telemundo report said [12].

Government agencies have not yet released a full assessment of the infrastructure damage across the country, but the scale of the building collapses suggests significant urban destruction in the epicentral zone.

The high death toll and the number of collapsed buildings highlight the vulnerability of infrastructure in the Chocó region to high-magnitude seismic events. Because the quake was felt across three other nations, it underscores the regional risk associated with the tectonic activity of the Andean volcanic belt and the need for coordinated cross-border disaster response protocols in South America.
