The present undergraduate thesis addresses a relevant topic, both for the scientific community and for people residing in landslide-prone areas caused by the removal of vegetation cover from areas of land with high inclination, rough terrain, and improper housing locations, offering favorable conditions for landslides on slopes during the rainy season. With this research, we analyze the spatial variability of soil resistance in landslide-prone locations of slopes in the city of Recife and its relationship with the identified events in the monitoring area. The selected area for monitoring, located in Ibura Recife - PE, was one of the areas affected by the disaster that occurred in May 2022 in Recife, PE, which caused numerous human losses and the destruction of homes. The determination of shear was done through the Standard Penetration Test (SPT) for obtaining data in the locations where landslides occurred and in their vicinity. As results obtained, we analyzed the correlation by the Pearson coefficient, obtaining positive and significant results. Taking the results into consideration, we had several conclusions, such as a direct correlation between the allowable stress of a point that slid and a point that did not slide.
