Jotiba-Panhala hill range trending eastwest and play a vital role as a water divider between Panchaganga and Varna rivers sub-basins in Kolhapur district, Maharashtra. For present research 483.7 sq. km. area is selected for mass wasting zonation analysis. The highest elevation in area is 991 meters and the lowest is 533 meters. The drainage pattern observed is dendritic to sub dendritic. Most of the area shows high drainage density and stream frequency indicating the area is low permeability in nature. Geologically, study area belongs to Deccan Volcanic Province (DVP) of Upper Cretaceous to Lowe Eocene age. On the top of the hill laterite rock is formed due to in situ chemical weathering of basalt. It is of late Pleistocene age. Lithostratigraphically, study area is belongs to Mahableshwar formation of Upper Deccan Traps. In present study, Remote sensing and Geographical Information System (GIS) techniques are used with the help of Resourcesat1, LISS-III, 24 m., satellite image January 2013 (Downloaded from Bhuvan), SRTM DEM-1-arc~30 meter resolution (Downloaded from USGS) and SOI toposheets on 1:50000 scale with adequate ground truth in ArcGIS 10.1 and ERDAS 2014 software. In the present research, it is found that weathered parts of lava flows, regoliths and talus deposits, during rainy season due to heavy rainfall in short period of time lose their strength and landslides occurs. High rainfall generally is the main cause of landslides. Some other causes are terrain factors such as slope, lithology, geological structures, land use/ land cover and geomorphology of the area. Finally Landslide susceptible zone map is developed for planning, development and risk management.
