Determinación de zonas susceptibles a deslizamientos en el casco urbano de General Leonidas Plaza a través del método Mora Vahrson

Abstract

The investigation proposes: to determine the areas susceptible to mass removal phenomena in the urban area of the general Leonidas Plaza parish, of the canton Limon Indanza, in the province of Morona Santiago; The final result of this project will be a thematic map obtained after the application of the Mora Vahrson method, which will be divided into 3 zones. The Mora Vahrson method determines the degree of susceptibility to landslides for tropical and subtropical zones with high rates of precipitation and incidence of seismic activity; is composed of five factors: three intrinsic factors (Topography or relief, soil moisture and rock mass) and two trigger factors (seismicity and precipitation). The intrinsic factors were obtained from the geological and geotechnical survey, the seismicity factor was obtained by the application of the Goldsack Seismic Attenuation Law, and the precipitation factor data were taken from the nearest meteorological stations. In addition, two maps, the geological map and the soil map were elaborated; the soil map was elaborated to represent the types of soils in the study area. It is concluded that the zone 3, located to the southwest of the urban hull, presents greater susceptibility to mass removal phenomena, with lithology and precipitation as the most important and influential factors in that zone.
