TXT-tool 1.052-1.1 GIS using landslides inventory mapping for volcanoes

Abstract

This tool is a systematic method for carrying out a landslide inventory on Quaternary volcanoes. The goal of this tool is to provide the foundation for mapping landslides in volcanic areas using Geographic Information System (GIS). The mapping methodology uses aerial photographs, fieldwork, and adaptation of the Landslide Hazard Zonation Protocol of the Washington State Department of Natural Resources, USA to address the distribution, type, and abundance of landslides. The training area is along the Río La Carbonera watershed on the SE flank of Pico de Orizaba volcano, Mexico. The area is predisposed to landslides due to physiographic conditions (loose volcanic materials and high seasonal rainfall) and decades of deforestation.
