Magnitude 7.4 Earthquake Strikes Western Colombia, Killing Dozens

A magnitude 7.4 earthquake struck western Colombia on 10 August 2026, centred about two kilometres southeast of San José del Palmar in Chocó department, according to the US Geological Survey (USGS). The quake occurred at a depth of roughly 108 kilometres and was felt strongly as far away as the capital, Bogotá, some 250 miles to the east.

Casualties and Damage

Colombian authorities reported dozens of deaths in the immediate aftermath, with the toll rising over subsequent days as rescue teams reached more remote areas, alongside hundreds of injuries. Local reporting described collapsed buildings, damaged health centres, schools and roads across the affected departments, with entire blocks of masonry structures reduced to rubble in some towns. The Colombian Geological Survey described it as the country’s strongest earthquake in a decade and the largest since a major 1979 quake struck the Pacific coast near Tumaco.

Government Response

Colombia’s government declared a state of national disaster and deployed soldiers to support search-and-rescue and relief operations in the hardest-hit municipalities. The USGS estimated that more than 10 million people experienced strong to very strong shaking, reflecting the wide geographic reach of the quake across Colombia’s mountainous interior. Aid organisations, including World Central Kitchen, moved quickly to distribute food and supplies to families displaced from damaged buildings in Chocó and neighbouring departments.

Why It Matters

Colombia sits along the Pacific Ring of Fire, where the Nazca and South American tectonic plates converge, making the country periodically vulnerable to large, damaging earthquakes. The scale of destruction in Chocó has renewed attention on building standards and emergency preparedness in Colombia’s smaller, less-resourced municipalities, which often lack the reinforced construction found in larger cities, and officials have signalled that reconstruction funding will be a central part of the national disaster declaration’s follow-through, with recovery expected to stretch over months given the number of damaged health centres and schools.
