52 days have passed since the M7.4 earthquake struck Chocó on August 10. Official figures remain at 326 deaths, 4600 injured, and 234 missing. No aftershocks were recorded in the past 24 hours, signaling a continued decline in seismic activity.
General Overview
As of 12:05 on October 1, 2026, 52 days have passed 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.
Recent Seismic Activity
For the first time in weeks, no aftershocks were recorded in the past 24 hours according to USGS data. This absence of seismic activity represents a significant milestone in the geological stabilization process of the region. The strongest aftershock recorded since the main earthquake remains at magnitude 4.5.
In previous weeks, the region experienced moderate seismic activity with aftershocks of magnitude 4.8, 4.6, and 4.5 in areas near Sipí, Roncesvalles, and San Antonio, but the overall trend shows a sustained decrease in both frequency and intensity.
Infrastructure Impact
Documented material damage remains at 10677 homes destroyed and 65841 homes damaged. Additionally, 127 buildings collapsed during the main seismic event. An estimated 185500 people have been directly or indirectly affected by the disaster.
Reconstruction efforts continue in the most affected areas, with engineering teams assessing the structural safety of damaged buildings before authorizing residents' return.
Humanitarian Response
Search and rescue operations have concluded, and current efforts focus on medium and long-term recovery. The Colombian Red Cross maintains a field presence coordinating humanitarian assistance, while international organizations such as the World Food Programme continue supporting supply distribution.

Outlook
The absence of aftershocks in the past 24 hours is a positive sign, although authorities maintain active monitoring systems. The Colombian Geological Service continues to monitor regional seismic activity.
The emergency phase has given way to recovery and reconstruction, with emphasis on implementing earthquake-resistant construction standards to reduce future vulnerabilities.
