A powerful earthquake struck western Colombia on Monday, causing building collapses and multiple deaths across the region [1], [2].
The disaster highlights the vulnerability of regional infrastructure to high-magnitude seismic activity in a zone known for tectonic instability.
Reports on the strength of the quake vary among geological agencies. The U.S. Geological Survey reported a magnitude of 7.4 [3], while the Colombian geological service provided figures ranging from 6.6 [4] to seven [5]. The epicentre was located approximately 100 km deep [3].
Casualty figures have fluctuated as emergency responders navigate the damage. Initial reports cited 18 deaths [1] and at least 20 deaths [5]. Later reports provided a wider range, with one source stating at least 21 people died [6] and another reporting at least 47 confirmed dead [4].
The tremors were felt beyond Colombia, impacting neighboring Latin American countries. Emergency responders have been deployed to manage building collapses and search for survivors in the affected areas [1], [2].
Geologists from both Colombian and U.S. services recorded the event as a result of natural tectonic activity [3], [4]. The depth of the quake may have influenced the distribution of surface damage, though the intensity was sufficient to destroy structures in several locations [1].
Local authorities continue to assess the full extent of the injuries and structural damage across the region as rescue operations proceed [1], [2].

The discrepancy in magnitude and casualty reports reflects the chaotic early stages of disaster response in remote or heavily damaged areas. Because the epicentre was 100 km deep, the seismic energy was distributed over a wider area, which explains why the effects were felt across multiple Latin American borders rather than being concentrated in a single city.
