Resumen:

In Mexico, numerous GIS-based applications have been used to represent and assess slope stability. However, there is not a practical and standardized landslide mapping methodology under the GIS system. This work aims to illustrate a comprehensive methodology to characterize areas that are prone to slope instability. The Río Chiquito-Barranca del Muerto watershed on the southwestern flank of Pico de Orizaba volcano, the highest mountain in Mexico, was selected as study area. The study area has a combination of several contributing factors to landslides such as high rain fall during the wet season, rock types, high degree of weathering, and steep slopes. The methodology encompasses three main stages of analysis to assess landslide hazards. The technique and its implementation in a GIS-based technology is presented and discussed. © Springer-Verlag Berlin Heidelberg 2013.
