Más de 1.100 sismos en 11 días sacudieron Chaparral, Tolima: el SGC explicó por qué se registró esta secuencia inédita en la zona

Between September 20 and 30, 2026, the municipality of Chaparral in the Tolima department experienced a seismic swarm consisting of more than 1,100 earthquakes, all registering magnitudes above 2.0.

The unprecedented frequency and volume of the tremors prompted the Servicio Geológico Colombiano (SGC) to step up its monitoring and scientific analysis of the area to determine the geological drivers behind the activity.
