A 7.4-magnitude earthquake struck western Colombia on Monday, causing buildings to collapse and killing at least 111 people [1, 2].
The disaster has paralyzed several urban centers, most notably Cali, where rescue teams are searching for survivors trapped under heaps of rubble. The scale of the destruction highlights the vulnerability of urban infrastructure in the region to high-magnitude seismic events.
The earthquake occurred at a depth of approximately 96 km [4]. While the epicenter was located in western Colombia, the tremors were felt in Bogotá, Medellín, and neighboring countries [1, 5]. The epicenter was located approximately 250 miles west of Bogotá [5].
Death tolls vary across reports as emergency services continue to survey the damage. AFP and the Associated Press said at least 111 deaths were confirmed [2]. However, The New York Times said at least 28 people died [3], while other reports cited over a dozen fatalities [6]. Local officials, including the mayor of Cali, are coordinating evacuation efforts and emergency responses in the affected cities [1, 5].
Emergency crews are focusing their efforts on Cali, where the most significant structural failures occurred. Residents in the region have been forced to evacuate their homes and buildings as aftershocks remain a concern [5]. The intensity of the 7.4-magnitude quake [1] has left several city streets blocked by debris, complicating the arrival of heavy machinery needed for rescue operations.
Authorities have not yet released a final count of the injured, but the collapse of multiple residential and commercial buildings suggests a high number of casualties. Search-and-rescue teams are utilizing specialized equipment to locate survivors beneath the concrete [1].

The discrepancy in death tolls reflects the chaotic early stages of disaster response in a high-density urban environment. The depth of the quake—nearly 100 km—usually mitigates some surface destruction, but the total collapse of buildings in Cali suggests significant failures in local building codes or soil stability. This event will likely prompt a review of seismic safety standards across western Colombia's major cities.
