The city of San Juan de Pasto (Colombia) is located in an high level seismic hazard area, due to the tectonic environment, and the Galeras volcanic activity. The Galeras Vulcano is located eleven kilometers to the west of the city and it is been identified like one of the most active of Colombia. The eruption history indicates that it has been characterized mainly for the occurrence of pyroclastic flows, which constitutes a significant hazard.
