A magnitude 7.4 [1] earthquake struck western Colombia on Monday, killing dozens of people and collapsing buildings in the Chocó region.
The disaster underscores the extreme vulnerability of rural Colombian infrastructure to seismic activity, as the region sits on the volatile Pacific-Nazca plate boundary [1, 5].
The epicentre was located in San José del Palmar, a community of approximately 4,800 residents [1]. The quake occurred about 400 km west of Bogotá [1, 3], triggering widespread panic and forcing immediate evacuations across the western coast.
Reports on the death toll vary among news agencies. Some outlets, including the Associated Press and OANN, report that at least 111 people died [1, 4]. Other reports, including those from the Times of Israel, state at least 73 people died [3].
In San José del Palmar, residents spent Monday searching through rubble for survivors as residential structures crumbled. The scale of the collapse has trapped many individuals under debris, complicating rescue efforts in the remote region.
Local authorities and emergency responders are working to reach isolated areas of Chocó. The magnitude of the quake caused significant damage to local infrastructure, hindering the movement of aid, and medical supplies to the hardest-hit zones.
Tectonic activity along the plate boundary generated the strong tremors [1, 5]. This geological instability makes western Colombia prone to such events, though the intensity of this specific quake has caused devastation that exceeds recent historical norms for the area.

This event highlights the ongoing risk posed by the Pacific-Nazca plate boundary to Colombia's western coast. The disparity in reported casualty figures suggests a chaotic early response phase in a remote region where communication infrastructure is often limited, potentially delaying the full assessment of the humanitarian crisis.
