Zonificación de la Susceptibilidad por Fenómenos de Remoción en Masa en el Distrito Metropolitano de Quito (DMQ)

Abstract

In the present study, the FRM susceptibility map is made, at a scale of 1: 10,000 in the Distrito Metropolitano de Quito, through the application of the Jiménez Perálvarez Matrix Method, which is based on a bivariate statistical analysis of the characteristic determining factors from the slopes of the study area such as: lithology and the Mass Removal Phenomena (FRM) Inventory Map where the unstable areas are located; and determining factors derived from the terrain model DEM: height, angle of the slope and orientation of the slopes. This method is developed through a GIS application in which the correlation of the mapping of the aforementioned factors is performed. Finally with the map of susceptibility for FRM there obtained a percentage 57,84 % of the total area that are in an Average, High and Very high like that susceptibility showing the zones most inclined to FRM's occurrence. This map allows to delimit the zones most inclined to the generation of Phenomena of Removal in Mass, to raise alternatives of prevention and mitigation that they will contribute in the improvement of the quality of life of the population of the Metropolitan District of Quito, across mechanisms of territorial planning.
