A magnitude-7.4 earthquake struck western Colombia on Monday, killing more than 100 people and causing widespread building collapses [1, 4, 5].

The disaster has prompted a national state of emergency as rescue teams scramble to locate survivors in remote regions. The scale of the destruction threatens local infrastructure and complicates relief efforts in the western territories.

President Gustavo Petro declared the state of emergency following the tectonic event [1]. The earthquake's epicentre was located near San José del Palmar in the Chocó region [3, 6], approximately 250 miles west of Bogotá [6]. While the most severe damage occurred in the west, the tremors were felt as far as the capital city of Bogotá [3].

Casualty reports vary as search and rescue operations continue. Al Jazeera said at least 132 people died [3], while MSN said at least 111 died [2]. Other reports from the AP via KFOR listed the death toll at at least 47 [1]. A summary of the event indicated that more than 100 people died [5].

In addition to the fatalities, hundreds of people were injured [2]. The quake caused significant structural failure, with multiple buildings collapsing in the affected areas [1, 5]. Emergency responders are currently focusing on the Chocó region to extract victims from the rubble.

Local authorities have not yet provided a final count of the displaced or the total cost of the infrastructure damage. The government is coordinating with international agencies to manage the crisis, a move intended to accelerate the delivery of medical supplies and food to the isolated epicentre.

The disparity in death toll reports highlights the difficulty of coordinating communications in Colombia's western regions, particularly in the Chocó area. This event underscores the vulnerability of rural infrastructure to high-magnitude tectonic activity and will likely lead to a review of building codes in the Andean and Pacific coastal regions.
