A magnitude-7.4 earthquake struck northwest Colombia on Monday, killing at least 20 people [1, 2] and causing multiple buildings to collapse [1].

The disaster highlights the vulnerability of urban infrastructure in the region's seismic zones, as rescue teams race to find survivors buried under rubble.

Emergency crews are operating in Pereira, the capital of the Risaralda department, where the shaking caused severe structural failures [2, 3]. Video footage captured the moment a three-story building collapsed [3, 4]. Other reports indicate that part of the Universidad Libre also suffered a collapse during the event [5].

The death toll currently stands at a minimum of 20 people [1], though authorities expect that number to rise as search operations continue. Many others were injured, and some residents remain trapped in damaged structures [1].

In one specific rescue effort, reports emerged of a woman trapped on the top floor of a building in Pereira [6]. Her family members said they feared the remaining structure would collapse further, complicating the extraction process [6].

Rescue teams and local authorities are working to stabilize ruins to prevent further casualties. The earthquake's epicenter was located in the northwest of the country, sending shockwaves through several departments [1].

Local officials said the intensity of the shaking led to immediate failures in buildings that may not have met modern seismic standards. The search for survivors remains the primary focus for first responders as they navigate the debris in Pereira [2, 3].

This event underscores the ongoing risk posed by seismic activity in the Andean region of Colombia. The collapse of both residential and educational structures in Pereira suggests a potential gap in the enforcement of building codes or the aging of critical infrastructure, which increases the lethality of high-magnitude quakes in densely populated urban centers.
