Abstarct: Landslides, due to their dangerous nature, quickly affect the structure of landslide-prone areas and cause major damage to infrastructure, buildings, roads, etc. In this study, landslides and slope stability in the area of Hosseinabad Kalposh village of Miami city in Semnan province have been investigated.
In this study, Sentinel-1 satellite images have been used, using radar interferometry technique, to evaluate and identify areas prone to fall. In the next step, the results were analyzed in GIS environment. Finally, subsurface identifications have been performed to verify the results. The results of interference measurement of Sentinel-1 radar data with DInSAR technique in a period of 12 days show displacements of about 7 cm in the northern and northwestern slopes, about 3 to 4 cm in the western slopes and 1 to 3 cm in the eastern and northeast slopes. In the area of communication roads of the village, shifts of about 3 cm have been observed. Subsurface identifications also indicated low-paste clay soils with a low SPT number. Due to the presence of groundwater, heavy rainfall and lack of soil reinforcement by the roots of trees, the soil has become saturated and with the increase of trapping properties, it has lost its shear strength and has been lubricated.
