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

The disaster underscores the vulnerability of infrastructure in the Chocó region, where remote geography often complicates emergency response and rescue efforts during seismic events.

The earthquake occurred at 12:34 UTC, or approximately 7:34 AM local time, centered about five km east of San José del Palmar [1], [2]. The tremor originated at a depth of approximately 107 km [1]. While the USGS measured the magnitude at 7.4 [1], the U.S. Tsunami Warning System recorded it at 7.1 [1].

Casualty reports vary as rescue operations continue. CBC said there were at least 20 deaths [3], while the Houston Chronicle cited a higher figure of 47 dead [4]. Local authorities have managed widespread evacuations of homes and buildings across western Colombia [5].

The impact of the quake extended beyond Colombian borders, with tremors felt in neighboring Venezuela [2], [3]. In the hardest-hit areas of the Chocó department, rescue crews are working through debris to locate survivors among the collapsed structures [5].

Emergency services are currently prioritizing the stabilization of damaged buildings to prevent further casualties. The regional government has not yet released a full assessment of the economic damage, or the total number of displaced residents.

The discrepancy in death tolls and magnitude measurements highlights the chaos of the immediate aftermath of a major seismic event. Because the quake struck a deep focal point of 107 km, the energy was distributed over a wider area, explaining why tremors were felt as far as Venezuela despite the epicenter being localized in the Chocó department.
