Situation Report: M7.4 Chocó Earthquake - October 3, 2026
54 days after the August 10 earthquake, official figures remain at 326 deaths, 4600 injured, and 234 missing. No aftershocks were recorded in the last 24 hours, signaling continued decline in seismic activity.
Situation Overview
Today, October 3, 2026, marks 54 days since the magnitude 7.4 earthquake struck the Chocó department on August 10. Official casualty figures remain unchanged: 326 people dead, 4600 injured, and 234 people missing.
Seismic Activity
For the first time in weeks, no aftershocks were recorded in the last 24 hours, according to data from the United States Geological Survey. This absence of seismic activity represents a significant milestone in the aftershock sequence that has followed the main event.
The strongest aftershock recorded since the main event remains at magnitude 4.5. During previous weeks, the region experienced multiple aftershocks of magnitude 4.0 or greater, with events near Roncesvalles, San Antonio, Sipí, and Rioblanco.
Infrastructure Damage
Documented material damage includes:
- 10677 homes destroyed - 65841 homes damaged - 127 buildings collapsed - 185500 people affected in total
These figures reflect the devastating impact of the earthquake on communities in Colombia's Pacific region, where many structures were not designed to withstand earthquakes of this magnitude.
Recovery Efforts
Colombian authorities, in coordination with national and international humanitarian organizations, continue working on long-term recovery. The Colombian Red Cross maintains operations in affected areas, while United Nations agencies and the World Food Programme continue providing logistical and humanitarian support.
The National Unit for Disaster Risk Management coordinates reconstruction efforts, with emphasis on building earthquake-resistant housing and strengthening critical infrastructure.
Search for Missing Persons
The 234 people who remain missing continue to be sought through platforms such as Colombia Te Busca and Desaparecidos.co, which facilitate family reunification.
Outlook
The absence of aftershocks in the last 24 hours is a positive sign, although experts warn that the possibility of additional seismic activity persists. Affected communities now face the challenge of long-term reconstruction, with ongoing needs for housing, basic services, and psychosocial support.
