Estudio de Zonas de Remoción en Masa por Deslizamiento de Tierras para el Área Metropolitana de Cúcuta Utilizando Herramientas SIG

Abstract

This study arises from the need to generate an input that would be the basis for locating threats landslide, since in the study area no mapping and spatial information at the time to this subject is evident , therefore, based on existing information la Mora methodology is chosen - Varhson , a methodology that is appropriate for that purpose and to generate trend zones where the ground is unstable for the six existing municipalities in the metropolitan area of Cucuta , classifying them into six ranges: Very high , high, medium , moderate, low and very low . The study found the calculations concerning the three intrinsic factors ( lithology , soil moisture and earrings ) and two detonators ( triggered by rains and triggered by seismicity ), which allowed to define the areas threatened by landslides and use SIG tools to reach this goal
