A magnitude-7.4 earthquake struck western Colombia on Monday, killing at least 111 people and leaving more than 1,900 missing [1, 2].

The scale of the disaster has crippled regional infrastructure and created a massive humanitarian crisis in one of the country's most remote provinces. The high number of missing persons suggests the death toll may rise as rescue teams reach collapsed structures.

The epicenter was located near San José del Palmar in Chocó province [1, 5]. Tectonic activity triggered the powerful tremor, which was felt as far as Ecuador [1]. In the hardest-hit areas, the quake caused widespread building collapses, trapping residents and workers beneath concrete and debris [1, 2].

Colombian authorities and rescue teams are conducting search-and-rescue operations throughout the region. Military personnel have been deployed to assist in digging through ruins and locating survivors [1]. The logistical effort is complicated by the closure of six regional airports, which has hindered the rapid transport of aid and personnel [2].

While some early reports indicated lower casualty figures, later updates confirmed that 111 people have died [2, 3]. The discrepancy reflects the evolving nature of the search efforts as teams penetrate deeper into the affected zones of Chocó province.

Residents in the region remain on alert for aftershocks. Authorities said that damaged buildings may be unstable, posing further risks to both survivors and the first responders working to clear the wreckage [1, 2].

A magnitude-7.4 earthquake struck western Colombia on Monday, killing at least 111 people.

The magnitude of this event and the resulting infrastructure failure, specifically the closure of six airports, highlight the vulnerability of western Colombia's remote provinces to seismic activity. The gap between initial death reports and the current toll of 111 indicates a high volume of structural collapses, suggesting that the 1,900 missing individuals may face low survival rates as the window for rescue narrows.
