Rescue crews are searching for survivors in western Colombia after a magnitude 7.4 earthquake [1] struck on Monday, Aug. 11.

The disaster has caused widespread building collapses in the Chocó region near Cali, triggering a massive humanitarian crisis as thousands remain trapped under rubble.

Search-and-rescue teams are coordinating with local authorities to locate missing persons. Reports on the death toll vary as the situation evolves. Newsday and the Associated Press reported 111 deaths [2, 3], while CNN reported at least 175 [4]. Other reports from MSN US and MSN South Africa cited 181 [5] and 164 deaths [6], respectively. A Reuters video summary stated that more than 200 people have died [7].

The scale of the injury list is similarly divergent. CNN reported hundreds of injuries [4], while MSN South Africa reported more than 880 [6]. The number of missing persons is estimated to be more than 3,000 [8, 9].

Emergency responders are working through the debris of collapsed structures to find survivors. The earthquake's impact has been most severe in the Chocó region, where infrastructure damage has complicated the arrival of aid and the movement of rescue crews.

Local authorities said the operations are ongoing. The focus remains on the most heavily damaged urban centers where the risk of further collapse remains high.

The discrepancy in casualty figures suggests a chaotic reporting environment typical of the immediate aftermath of a major seismic event. The high number of missing persons relative to confirmed deaths indicates that the death toll is likely to rise significantly as rescue teams reach more remote areas of the Chocó region.
