At 07:34 on Monday 10 August 2026, as children travelled to school and cities began the working week, a magnitude 7.4 earthquake struck western Colombia, its epicentre beneath San José del Palmar, a remote municipality in Chocó department. It was the strongest earthquake to hit Colombia in a decade, felt from the Pacific coast to Bogotá. By the evening of 12 August the official toll stood at 241 deaths, 3,771 injured and 287 missing, with more than 54,000 homes damaged or destroyed across 13 departments and 395 municipalities.
This deep dive assembles the record three days in: the official toll and where it is concentrated, a building-by-building satellite damage assessment of Pereira from data published on the Humanitarian Data Exchange, the pre-existing crisis the earthquake landed on, and the money mobilised against the money needed.
A deep rupture under the Pacific margin
The Colombian Geological Service placed the hypocentre at roughly 82 kilometres depth (USGS modelling used approximately 96 km). That depth spread the shaking widely rather than concentrating it: 16 of Colombia's 32 departments initially reported impacts, and damage now spans from Chocó through the coffee-axis cities of Pereira, Manizales and Armenia to Cali. The President declared a National Disaster Situation within hours; 103 aftershocks had followed by 12 August, all in the epicentral municipality.
Where the deaths and the damage are
The mortality is concentrated away from the epicentre. Sparsely populated Chocó recorded 27 deaths; the harm concentrated where strong shaking met dense, older building stock: 132 deaths in Valle del Cauca and 95 in Risaralda, whose capital Pereira sits barely 60 kilometres from the epicentre. The pattern repeats in the infrastructure numbers: more than 30,000 affected structures in Valle del Cauca alone, and Cali's hospital network on red alert even as services stabilise.
| Department | Affected people | Deaths | Missing | Affected structures |
|---|---|---|---|---|
| Valle del Cauca | 35,988 | 132 | 238 | 30,109 |
| Chocó | 22,810 | 27 | 8 | 5,107 |
| Risaralda | — | 95 | 45 | 7,178 |
| Caldas | — | 6 | — | 7,021 |
| Quindío | — | 1 | — | 3,596 |
| Cauca | — | — | — | 1,523 |

Pereira, building by building
While ground damage assessments (DANA) work municipality by municipality, satellite analysis is already producing building-level triage. On 12 August, Vantor published an AI damage assessment of Pereira on the Humanitarian Data Exchange: every one of 75,262 building footprints in the imaged area was scored against post-event imagery, and 613 buildings were flagged as damaged, 169 of them severely. The map below renders each flagged building's actual footprint; use the filters to isolate severity bands.
A disaster on top of a crisis
The earthquake did not strike a blank map. WFP notes the affected departments were already carrying caseloads linked to conflict, displacement and climate shocks; the agency reaches roughly 100,000 people in Chocó, Valle del Cauca and Risaralda through existing operations. The Health Cluster's pre-earthquake presence mapping shows partners concentrated in exactly the departments now worst hit, a footprint built for the conflict response that is now the response platform for the quake. NRC warns the earthquake compounds already severe humanitarian needs in communities hosting displaced people.
Access is the multiplier. INVÍAS reported damage at 13 points on the national road network, including full closures of the Cali–Loboguerrero and Manizales–Fresno corridors, with six airports suspended; rescuers initially struggled to reach the epicentral zone in Chocó, where connectivity, electricity and water remain intermittent and the true rural toll is still being established. The response is also a political test: it is the new government's first major disaster, with international offers, including a 255-strong Mexican search-and-rescue contingent, arriving as domestic capacity strains.
Five million now, against needs still being counted
The national system moved fast on paper: a National Disaster Situation declared on day one, Unified Command Posts in six departments, USAR teams from four cities deployed, and clusters activated with assessments running in Quibdó, Cali, Pereira and Manizales. Internationally, the Emergency Relief Coordinator allocated US $5 million from CERF, with the Humanitarian Country Team meeting on 13 August to prioritise it. WFP alone estimates it needs US $23 million to feed 100,000 people, against US $4 million in unconfirmed forecasts, and the IFRC has a DREF allocation planned.
The wider funding context is unforgiving. Colombia's 2026 humanitarian response plan is 60% funded at US $285 million, respectable in a year when, as our GHA 2026 analysis showed, appeals globally met 35% of requirements. But the Venezuela regional plan's Colombia chapter sits at 11%, and every earthquake dollar now competes with a conflict response the system was already rationing.
Colombia is tracked live on PRISM: funding flows, displacement, food security, disaster alerts and protection indicators, updated from source as the response evolves.
