A powerful earthquake struck western Colombia on Monday, Aug. 5, 2024, causing buildings to collapse and leaving dozens of people dead [1, 4].
The disaster highlights the vulnerability of infrastructure in the Chocó region and surrounding cities, where residents were forced to flee falling debris as structures crumbled.
The quake occurred at 7:34 local time [6]. It originated at a depth of 107 km (66 miles) [3]. Reports on the strength of the tremor vary between agencies; the U.S. Geological Survey reported a magnitude of 7.4 [1], while the Colombian Geological Service measured it at 6.6 [2].
Casualty reports also differ across sources. The BBC reported that at least 47 people died [4], while CBC cited a lower estimate of at least 20 deaths [5]. Local authorities and residents in the Chocó region spent hours searching through rubble for survivors as debris continued to fall from damaged buildings.
Emergency crews responded to several nearby cities to manage the aftermath. The shaking was strong enough to trigger immediate evacuations in densely populated areas, where the force of the quake caused significant structural failure in older buildings.
“Buildings collapsed and debris fell as residents fled the rubble.”
The discrepancy in magnitude and death toll reports reflects the initial chaos of disaster response in remote regions like Chocó. The depth of the quake—over 100 km—typically mitigates some surface damage, but the collapse of buildings suggests that local construction standards may not meet the requirements for high-magnitude seismic events.
