A powerful 7.4-magnitude earthquake struck western Colombia and neighboring countries on Monday, causing widespread damage and prompting evacuations. The United States Geological Survey (USGS) and Colombia’s geological service reported the tremor occurred near the municipality of San Jose del Palmar in Colombia’s Choco region, approximately 400 km (250 miles) west of the capital, Bogota.

This seismic event underscores the region's vulnerability to earthquakes. The magnitude initially reported by Colombia's geological service was 6.6, but was later revised. The USGS indicated the quake originated at a depth of about 107 km (66 miles). Fortunately, the US tsunami warning system confirmed that no tsunami was generated.

Initial reports indicate significant casualties and structural damage. The mayor of Pereira reported 18 fatalities in his city, while Manizales confirmed two deaths. In Cali, at least 25 buildings collapsed, with authorities confirming at least one casualty and establishing a Unified Command Center to manage the emergency. The governor of Choco, Nubia Carolina Cordoba-Curi, expressed concern about aftershocks and reported injuries and significant damage to buildings in the regional capital, Quibdo, despite the epicenter being near San Jose del Palmar.

Authorities in Colombia and Ecuador have urged residents to remain vigilant as emergency teams continue to assess the full extent of the damage. The earthquake's impact was felt widely, triggering alarms and causing residents to flee buildings in Bogota and Medellin.

In the capital, Bogota, Mayor Carlos Galán reported no injuries and only minor building damage, stating the city's resources were available to assist affected areas. He confirmed that no serious structural damage occurred in Bogota, allowing their resources to be directed towards national support efforts.

Medellin experienced evacuation sirens, with residents leaving their homes. While no major building collapses or casualties were reported in the city, Mayor Federico Gutierrez suspended the metro's operations for necessary infrastructure checks. Smaller towns surrounding Medellin have reported structural issues, including collapsed roofs and fractured walls.

The affected region, particularly the Eje Cafetero, known for its tourism, saw footage of destroyed buildings broadcast by news outlets. The scale of destruction in cities like Pereira and Manizales highlights the devastating impact of the powerful tremor.

Emergency teams are continuing their assessment, and official reports on the full impact are expected to be issued as the situation develops. The focus remains on rescue efforts, damage evaluation, and providing assistance to those affected by this significant natural disaster.
