    This work presents the zoning of an area of the municipality of Carmen de Atrato through safety factors related to landslide considering the time categories: long, medium and short term, facilitating the analysis and zoning of risk and threat, using the slope methodology. natural resources (MSN), which requires only geology and topography as main inputs. The MSN provides a series of geomechanical and stability parameters for the determination of zones through the safety factor relative to landslide, which we herein call the landslide susceptibility index, in order to offer a practical tool in the generation of preliminary information in relation to the geomechanical parameters of the study area for engineering projects related to the field of geotechnics. The present work covers the following aspects for the determination of the safety factors related to the Fsr slide: a) Measurements of the slope families, b) Construction of the triangular pattern at the population level, c) Calculation of the basic friction angle, d ) Calculation of the envelopes for the calculation of geomechanical parameters of the delimited area, e) Calculation of safety factors related to the Fsr landslide, f) Risk zoning through the construction of isovalue maps. Finally, it is obtained that the basic friction angle obtained corresponds to that expected for this type of materials, for the relative safety factors the isovalue maps are presented, however, a better estimate of the possible occurrence of future events could be to implement a model considering precipitation up to 30 years and earthquakes for different return periods. It is important to remember that relative safety factors reflect past history, but do not take into account future triggering events. The inclusion of these triggers allows for a better estimate of the future probability of landslide failure. However, the calculation of the stability parameters presented in this work corresponds to a preliminary approach to the landslide susceptibility in the analyzed area, as well as the resistance parameters of geomaterials which are useful in civil engineering projects.
