ROBERTSON, Kim  and  CASTIBLANCO, Miguel A.. Fluvial Hazards in the Colombian Amazon Piedmont. Cuad. Geogr. Rev. Colomb. Geogr. [online]. 2011, vol.20, n.2, pp.125-137. ISSN 0121-215X.

The article presents the research results regarding the environmental threats caused by fluvial-volcanic or fluvial-torrential factors that could afect the population of the colombian amazon piedmont. This region includes a large area in the south-central part of the country regarding which there is deficient cartography and scarce secondary information about geology, geomorphology, hydrology, and climatology. For this reason, a regional geomorphologic analysis of satellite images (Landsat) and local aerial photos was carried out, which made it possible to identify the main geological formations and the morphodynamic processes associated with extreme environmental events. Finally, it was possible to identify three environmental factors capable of having great impact on the region: volcanic eruptions, strong earthquakes, and torrential rains.

Keywords : fluvial-volcanic fans; natural threats; geomorphology; neotectonics; Amazon Piedmont.
