The Colombian Geological Service (SGC) identified a seismic swarm in the Chocó region following the magnitude 7.4 earthquake that struck on August 10. ^[1] The Colombian Geological Service (SGC) reported a 4.3 magnitude earthquake with a depth of 43 kilometers that struck the Chocó department early on September 3, 2026. ^[2] Experts distinguish the seismic swarm from standard aftershocks because the swarm lacks a single dominant main event and does not show a progressive decrease in frequency. ^[3] The main earthquake occurred at 7:34 AM on August 10, with an epicenter in San José del Palmar at a depth of 103 kilometers. ^[4] The epicenter of the 4.3 magnitude earthquake was located at coordinates 4.42° latitude and -76.73° longitude, approximately 27 kilometers from Sipí in the Chocó department. ^[5] A third seismic event was recorded at 3:54 a.m. on September 3, 2026, with a depth of 44 kilometers, classified as a manual registration event. ^[6]
