A 7.4-magnitude earthquake struck western Colombia on Monday, killing at least 111 people [1].

The disaster has caused widespread structural failure in urban centers, triggering a massive rescue operation to locate thousands of residents trapped under collapsed buildings.

The quake primarily affected the city of Pereira and surrounding areas, including Cali and the Chocó region [1, 3]. Tectonic activity along the western fault lines of the country caused the seismic event [1]. President Abelardo de la Espriella declared a state of emergency following the disaster.

Emergency responders report that hundreds of buildings have been damaged or completely destroyed [1]. Search and rescue teams are currently working through debris to find survivors, though the scale of the destruction has complicated efforts. Official reports indicate that more than 3,000 people remain missing [2].

While the Associated Press reports at least 111 deaths [1], other reports have suggested higher tolls, including claims of 164 dead following a hospital collapse in Cali. The government has not yet reconciled these figures. Reports also vary regarding the impact on the capital, with some sources indicating deaths in Bogotá while others focus exclusively on the western region.

The Chocó region and the city of Pereira have seen the most severe impact. Local authorities said the magnitude of the quake caused immediate collapses of residential structures, and public infrastructure [1, 3].

Rescue crews continue to operate across the affected provinces. The state of emergency allows the government to mobilize military resources and international aid to manage the crisis and provide medical care to the injured [1].

This event underscores the vulnerability of Colombia's western infrastructure to tectonic activity. The discrepancy in death tolls between primary news agencies and other outlets suggests a chaotic early reporting phase typical of large-scale disasters, where local collapses—such as the reported hospital failure in Cali—may not be immediately reflected in national totals.
