TXT-tool 1.052-1.2: GIS using landslides susceptibility mapping model for volcanoes

Abstract

This tool is a systematic methodology for making landslide susceptibility maps using GIS technology. The main goal of this tool is to provide the foundation for mapping landslides susceptibility per landforms in areas where there is little information. Derivation of landform units used classification of morphometric parameters, expert knowledge, field verification, and adaptation of the Landslide Hazard Zonation Protocol of the Washington State Department of Natural Resources, USA. For each landform the landslide area rate (LAR) and the landslide frequency rate (LFR) is calculated in order to determine the landslide susceptibility. The training area is along the stream system of Río La Carbonera watershed on the SE flank of Pico de Orizaba volcano, Mexico.
