A region already in need

The earthquake affected Chocó and Valle del Cauca, among the most affected departments.

Before the earthquake, more than 1.2 million people in Chocó and Valle del Cauca needed humanitarian assistance, representing more than 20% of the population there, according to ReliefWeb and HCN Times. The exact date of the estimate is not specified.

According to the 21 August 2026 Humanitarian Country Team and UN OCHA press release, a magnitude-7.4 earthquake affected 15 departments and approximately 470 municipalities, primarily Chocó, Valle del Cauca, Risaralda, and Caldas.

Colombia's Humanitarian Country Team announced an addendum to the 2026 Humanitarian Needs and Response Plan on 21 August 2026, according to the same release. The release reports that Colombia's pre-existing humanitarian situation affected 6.9 million people, and that 1.2 million people developed new humanitarian assistance needs as a direct result of the earthquake emergency. The earthquake increased the vulnerability of millions of people in Colombia, according to the release. The addendum aims to mobilize resources to save lives and support people with the most acute needs, according to the release.

WFP's brief dated 23 October 2026 estimated that the 10 August 2026 earthquake affected approximately 466,606 people across 15 departments. According to the brief, preliminary assessments found that the earthquake disrupted livelihoods, local markets and essential services, increasing food-security risks and humanitarian needs related to shelter, early recovery and food assistance.

The same WFP brief dated 23 October 2026 reported that WFP assisted approximately 423,427 people in Colombia from January to July 2026 through food assistance and cash-based transfers. WFP also reported in that brief that 37 percent of households in Colombia's 15 most vulnerable departments, equivalent to approximately 7 million people, experienced moderate or severe food insecurity, and that national food insecurity remained around 25 percent, with Atlántico, Sucre and La Guajira having the highest prevalence of severe food insecurity, according to WFP's joint food-security assessment.

WFP's brief dated 23 October 2026 described Colombia's humanitarian and food-security crisis as compounded by persistent violence, forced displacement, non-state armed groups, mixed migration, natural hazards and economic shocks.

A UNHCR report published on 19 October 2026 says that, two months after the earthquake, the response had shifted from emergency operations toward early recovery. UNHCR reported approximately 315,000 refugees were hosted in affected municipalities, including about 202,000 in Valle del Cauca. UNHCR reported that more than 1.1 million Afro-descendant people and 214,000 Indigenous people lived in the affected areas and faced heightened protection risks, including family separation, gender-based violence, loss of documentation, confinement, recruitment, and displacement.
