Los sistemas de informacion geográficos en la zonificación de amenaza por deslizamientos.

Abstract

Colombia is a country where there are different natural eventualities being the landslide or landslide one of the main and frequent phenomena that occur, being the departments of the Andean area one of the most affected by this, particularly Antioquia, Boyacá, Caldas, Cundinamarca , Huila, Norte de Santander, Quindio, Risaralda, Santander and Tolima. For this reason, it was pertinent to identify Identify how the process of using the geographic information system occurs in terms of planning and reducing the impact on the zoning of threat due to landslides in Colombia, knowing that although this type of eventualities cannot be predicted with However, it is possible to identify areas susceptible to landslides. This work has discussed some of the concepts related to susceptibility to landslides: concepts and important considerations related to landslides and the mapping of landslide danger. The different types of landslides, the relative nature of the zoning of the landslide hazard; The different geoprocessing tools and the analysis of the techniques for mass movement zoning were also presented
