A magnitude 7.4 [1] earthquake struck western Colombia on Monday, killing at least 20 people [2] and collapsing dozens of buildings [3].

The disaster impacts several major urban centers in the region, raising immediate concerns regarding the stability of remaining infrastructure and the number of people trapped under rubble.

The seismic activity centered on western Colombia, with the most severe damage reported in the cities of Cali, Pereira, and Manizales [1]. In these areas, the force of the quake caused dozens of buildings to collapse [3]. Emergency responders have been working to locate survivors amid the debris, though the scale of the destruction has complicated rescue efforts.

Al Jazeera reporter Alessandro Rampietti said from the scene that the impact of the 7.4-magnitude [1] event remains visible across the cityscape. The death toll has risen to at least 20 [2] as search teams navigate the ruins of residential and commercial structures.

Local authorities have not yet released a final count of the injured, but the collapse of numerous buildings [3] suggests a high number of casualties. The event was identified as a tectonic earthquake [1].

Rescue teams continue to operate in the affected cities, focusing on the most heavily damaged sectors of Cali and its neighboring municipalities. Officials are monitoring the region for potential aftershocks that could further destabilize the already weakened buildings [3].

A magnitude 7.4 earthquake struck western Colombia on Monday, killing at least 20 people.

This event highlights the vulnerability of urban infrastructure in western Colombia to high-magnitude tectonic activity. The concentration of damage in three major cities—Cali, Pereira, and Manizales—suggests that the seismic waves hit densely populated areas, which typically increases the casualty rate and complicates the logistical response for emergency services.
