Abstract
The upper section of the Mapocho river basin is in constant danger of landslides. This study had the objective of zoning the upper Mapocho river basin for the susceptibility of landslides using hydrological, geological, and geomorphological data. Areas with a high degree of landslide susceptibility are located on the lower part of the main valleys as well as at the headwaters of the basins. Landslide events in the mountainous region of Central Chile are caused by two main factors: intense precipitation and seismic activity.
