A back-arc volcanic field with many pyroclastic cones lies in the Department of Huila, near the towns of San Augustín and Isnos, overlies an ignimbrite plain. Disappearance of the San Augustín culture between the 2nd century BCE and the first century CE has been attributed to invading armies or volcanic activity (Borrero et al., 2007).
