Chocó M7.4 Earthquake: Day 49 — Seismic activity decreases with 1 aftershock in last 24 hours
49 days after the M7.4 earthquake on August 10 in Chocó, seismic activity continues to decrease with only 1 aftershock recorded in the last 24 hours. Official figures remain at 326 deaths, 4600 injured, and 234 missing. More than 185500 people remain affected with 10677 homes destroyed.
General Situation
Seven weeks after the magnitude 7.4 earthquake that struck the department of Chocó on August 10, 2026, the region continues its recovery process while seismic activity shows a significant downward trend.
Recent Seismic Activity
In the last 24 hours, only 1 aftershock was recorded, with a maximum magnitude of 4.6. This reduction marks one of the quietest periods since the main shock, reflecting the gradual decrease in energy released in the rupture zone.
The magnitude 4.6 aftershock occurred 19 km southwest of Sipí on September 27, with no reports of additional damage. This reduced seismic activity is consistent with the expected pattern of aftershock decay according to Omori's Law.
Casualty Figures
Consolidated official figures as of September 28 remain at:
- 326 deaths - 4600 injured - 234 missing
Authorities continue working on victim identification and searching for missing persons. Families can consult registries at colombiatebusca.com and desaparecidos.co.
Infrastructure Damage
Documented material damages include:
- 10677 homes destroyed - 65841 homes partially damaged - 127 buildings collapsed - 185500 people affected
These figures represent one of the most significant natural disasters in Colombia's recent history, with particularly severe impacts on rural communities and indigenous and Afro-Colombian populations in Chocó.
Recovery Efforts
Humanitarian assistance operations continue, coordinated by the National Unit for Disaster Risk Management in collaboration with international organizations. The Colombian Red Cross maintains an active presence in the most affected areas, providing medical assistance, temporary shelter, and psychosocial support.
Reconstruction efforts face significant logistical challenges due to the remote geography of many affected communities and the climatic conditions of Colombia's Pacific region.
Scientific Perspective
The Colombian Geological Survey continues monitoring seismic activity in the region. The decrease in frequency and intensity of aftershocks is a positive sign, although experts warn that significant aftershocks are still possible in the coming weeks and months.
Resources and Assistance
Affected individuals can access information about assistance through:
- Presidency of the Republic - United Nations in Colombia - World Food Programme - Direct Relief
The international community maintains its commitment to the long-term recovery of communities affected by this devastating earthquake.
