Disaster-driven internal displacements per month (people)

According to IDMC's Internal Displacement Updates, Colombia recorded 96,846 disaster-driven internal displacements between 1 August and 31 August 2026, deduplicated to one figure per event. The total comes from 1 event, an earthquake in San José del Palmar, Chocó, dated 10 August 2026, with a displacement date of 28 August 2026 and sourced to Colombia's Unidad Nacional para la Gestión del Riesgo de Desastres (UNGRD). The alert fired because the monthly figure exceeded the fixed threshold of 50,000 displacements. No comparison with the country's own monthly record was made, as the available history covered 3 months against the 6 months required.
