Post-Earthquake Damages in an Urban Area^[1]

Current situation: A 7.4 magnitude earthquake with an epicenter in the Chocó Department has impacted several locations across Colombia.^[2] As of 1200 local time, the Colombian Geological Service has reported 18 aftershocks.^[3] 

Day/Time of event: August 10, 2026 / 0734 Local Time

What is the current threat:

• The Chocó Department will very likely experience further aftershocks, likely impacting surrounding departments, such as Antioquia, Risaralda, Caldas, and Valle del Cauca, elevating the toll of injured and dead people. These events will very likely damage critical infrastructure, causing the interruption of phone and internet services and complicating the assistance of emergency calls from victims. Transport blockages, such as fallen bridges and overpasses, damaged highways and roads, and bent railways, will very likely hinder initial escape and rescue efforts. Helicopters and small aircrafts will very likely become the most relied-upon method for delivering aid and transporting workers to the worst impacted sites. Authorities will almost certainly restrict airports from commercial use while emergency management adopts planes to bring in international aid provisions and rescue workers.

• Infrastructure damage like broken gas and water pipes and downed power lines will very likely pose a risk to both rescue workers and civilians. There is a roughly even chance that they will ignite fires in severely damaged areas, very likely complicating rescue efforts. Structurally impaired buildings will very likely experience shifts leading to collapses, worsened by aftershocks. Efforts to mitigate these risks will very likely take time and resources away from rescuing survivors, almost certainly delaying intervention from rescue teams and endangering trapped individuals in critical conditions.

• Authorities will very likely establish temporary collection and shelter centers across Chocó to provide early assistance for victims, likely using public buildings like schools and government facilities that remain in good condition. The national government will very likely mobilize first responders from nearby departments to mitigate the lack of personnel supporting victims. They will very likely assist in coordinating triage for injuries and gathering personal details of those arriving there.

• International relief actors such as the UN Office for the Coordination of Humanitarian Affairs (OCHA) and the International Rescue Committee (IRC) will very likely coordinate with local authorities in Colombia, Venezuela, Ecuador, and Panama to send and distribute first-aid kits to survivors and internally displaced persons (IDPs) in temporary shelters. Humanitarian agencies will likely prioritize distribution to urban centers with established relief infrastructures due to the ease of getting basic services to the latter, with informal local networks like spontaneous assistance groups within communities for basic medical care very likely becoming the main assistance for IDPs in isolated border areas.

Who will it directly impact:

• National government of Colombia

• Governments across departments close to the epicenter

• Aeronáutica Civil - Colombian Civil Aviation Authority

• National Police of Colombia

• Local emergency services, fire departments, and paramedics

• Rescue teams, specialized personnel, and trained search dog units

• Civilians impacted by the incident and assisting in rescue and recovery efforts

• Construction workers responsible for rebuilding

• Health and energy infrastructure across the departments near the epìcenter (Chocó, Antioquia, Risaralda, Caldas, and Valle del Cauca Department)

• Airports closed down for safety and required to receive international aid (supplies and workers)

• Ports in Chocó and Valle del Cauca Department

• Schools and universities in Colombia

• International Committee of the Red Cross (ICRC)

• OCHA

• IRC
