Landslide Inventory and Susceptibility Mapping in the El Estado Watershed, Pico de Orizaba Volcano, México
In Mexico, numerous GIS-based applications have been used to represent and assess slope stability.However, there is no practical and standardized landslide mapping methodology available within the GIS system.This work provides an overview of the ongoing research project (Grant SEP-CONACYT no 167495) from the Institute of Geography at the National Autonomous University of Mexico (UNAM) that seeks to conduct a multi-temporal landslide inventory, produce a landslide susceptibility map, and estimate sediment production by using Geographic Information Systems (GIS).For the latter two the Rio El Estado watershed on the southwestern flank of Pico de Orizaba volcano, the highest mountain in Mexico, is selected as a study area.The geologic and geomorphologic factors in combination with high seasonal precipitation, high degree of weathering, and steep slopes predispose the study area to landslides.The methodology encompasses three main stages of analysis to assess landslide hazards.The technique and its implementation of each stage in a GIS-based technology is presented and discussed.
