A magnitude-7.4 earthquake [1] struck northwest Colombia on Monday, killing hundreds of people and leaving thousands more injured or missing.

The disaster has triggered a massive emergency response in one of the region's most vulnerable areas, where structural collapses have trapped residents under rubble.

The city of Pereira was among the hardest hit by the seismic event [4]. Rescue operations are currently underway involving the Colombian army, firefighters, and volunteers working to locate survivors [1, 2]. President Abelardo De la Espriella has overseen the government's emergency response as teams navigate the ruins [2].

Casualty reports vary across agencies as the search continues. La República reported 265 deaths [2], while a Milenio report cited 239 dead [1]. Other reports provide lower estimates, with Perfil reporting 216 deaths [3] and MSN reporting 188 [4].

Beyond the fatalities, the human toll remains high. La República reported more than 1,000 injuries [2]. The scale of the disappearance is particularly acute, with Perfil reporting more than 4,000 people missing [3].

The tremors were felt far beyond the epicenter in northwest Colombia. Reports indicate the quake was felt in Bogotá and Cali, as well as in Quito, Ecuador, and Panama [1, 4].

Emergency crews are focusing on "crucial hours" to find survivors [2]. The widespread structural collapse has made access to certain areas difficult, necessitating the use of specialized equipment to clear debris and reach those trapped below.

The disparity in death tolls reflects the chaotic nature of early disaster reporting in high-collapse zones. The high number of missing persons relative to confirmed deaths suggests that the final casualty count will likely rise as rescue teams reach more remote or heavily damaged sectors of Pereira.
