A magnitude-7.4 earthquake [1] struck western Colombia on Monday, killing more than 250 people [2] and leaving thousands missing [3].

The disaster has devastated the coffee-growing valleys around Pereira and Cali, where widespread building collapses have trapped residents under rubble. The scale of the destruction threatens the regional economy and highlights the vulnerability of infrastructure in the Andean region.

Rescue operations are currently being led by the Colombian National Police, the military, local authorities, and various volunteer groups. Teams are working through the night to locate survivors in the debris of collapsed structures.

"The death toll is expected to rise as rescue teams continue their work throughout the night," a spokesperson for the Colombian National Police said [4].

Interior Minister Luis Gilberto Murillo emphasized the urgency of the mission as the window for successful rescues narrows. "We are racing against the clock to find survivors before the window of chance closes," Murillo said [5].

President Gustavo Petro has pledged the government's full support to the affected regions. "Our thoughts are with the families who have lost loved ones; we will not stop until every possible life is saved," Petro said [6].

Emergency crews in the hardest-hit areas have intermittently called for silence to listen for the sounds of survivors trapped beneath the concrete. Despite these efforts, the number of unaccounted-for persons remains in the thousands [3].

Local authorities are coordinating with international aid organizations to manage the influx of supplies and medical personnel. The focus remains on the cities of Pereira and Cali, where the most significant structural damage was reported [7].

“The death toll is expected to rise as rescue teams continue their work throughout the night.”

This event underscores the high seismic risk associated with Colombia's geography, particularly in the western valleys. The high death toll and number of missing persons suggest that existing building codes may have been insufficient to withstand a 7.4 magnitude event, potentially necessitating a national review of urban planning and infrastructure resilience in seismic zones.
