Abstract

Western Ghats on the western part of the Indian peninsula is recognized as the most frequent landslides potential zone. South west monsoon rainfall is major triggered factors of the landslide. The present work is carried out to evaluate the landslide susceptibility of Mahabaleshwar tehsil of Satara district, Maharashtra, India using geospatial technique. Landslides are influenced by several natural and manmade factors, such as slope, rainfall, relief, lithology, soil depth, soil erosion, soil texture, land use / land cover, road distance, drainage distance, drainage density, lineament distance, lineament density, aspect, temperature, seismology. The weighted overlay methods and multi-criteria model in ArcGIS 10.5 software were used for the mapping landslide susceptible zones. The landslide susceptible zones are classified into six classes: very high (0.3 %), high (2.2 %), moderate (6.4 %), low (14.2 %) very low (20.7 %) and no risk zone (56.2 %). Out of the total 113 villages of the tehsil, the study identified 06 villages are situated in very high, 18 in high, 13 in moderate, 19 in low and 17 in very low risk zones. The study has significant for the prevention and mitigation of the high landslide potential villages in the study area
