Report describing the findings of a hybrid reconnaissance effort conducted by the Geotechnical Extreme Events Reconnaissance (GEER) Network, the Colombian Geotechnical Society (Sociedad Colombiana de Geotecnia, SCG), and the Colombian Geological Survey (Servicio Geológico Colombiano, SGC).
Through field observations, remote sensing, and strong-motion analysis, the report documents widespread structural damage, landslides, road closures, and localized liquefaction across communities in Colombia, including Cali, Pereira, Manizales, and Chocó. While major infrastructure like dams and tailings facilities in the region experienced no major structural failures, the report highlights how complex source directivity, localized site response, steep terrain, and building vulnerabilities combined to create significant damage patterns. This research has important takeaways for updating regional seismic hazard models and urban microzonations.
