M7.4 Chocó Earthquake: 48 days later, seismic activity continues with moderate aftershocks
48 days after the August 10 earthquake, official figures remain at 326 deaths, 4600 injured, and 234 missing. Seismic activity persists with aftershocks up to magnitude 4.8 recorded in recent days.
General Situation
48 days have passed since the magnitude 7.4 earthquake struck the Chocó department on August 10, 2026. Official figures remain stable: 326 people deceased, 4600 injured, and 234 missing. Material devastation includes 10677 homes destroyed, 65841 homes damaged, and 127 buildings collapsed, affecting approximately 185500 people.
Recent Seismic Activity
The region continues to experience significant seismic activity. Multiple aftershocks have been recorded in the past 72 hours, notably a magnitude 4.8 event on September 19 located 29 km west-southwest of Sipí. Other notable aftershocks include three magnitude 4.6 events and several magnitude 4.5 tremors, primarily concentrated near Roncesvalles, Sipí, and San Antonio.
According to USGS data, no aftershocks of magnitude 3.0 or greater have been recorded in the last 24 hours, representing a temporary decrease in the frequency of detectable events. The strongest aftershock since the main event reached magnitude 4.6.
Recovery Efforts
Colombian authorities, in coordination with humanitarian organizations, continue working on the long-term recovery phase. The Colombian Red Cross maintains assistance operations in the most affected areas, while the World Food Programme continues supporting food aid distribution.
The National Unit for Disaster Risk Management coordinates reconstruction efforts, prioritizing the restoration of critical infrastructure and support for displaced families. The reconstruction process for thousands of destroyed and damaged homes represents a significant challenge that will require months, if not years, to complete.
Search for Missing Persons
The 234 people who remain missing continue to be a priority for authorities. Families can report cases and search for information through platforms such as Colombia Te Busca and Desaparecidos.co.
Outlook
Seismologists warn that aftershock activity may continue for months following an earthquake of this magnitude. The population in affected areas is urged to maintain preparedness for possible additional seismic events and to follow recommendations from the Colombian Geological Service.
The international community continues providing support, with organizations such as Direct Relief supplying medical resources and technical assistance for long-term recovery.
