Abstract

Landslide is one of the disasters which leads to large scale damage to properties and life. It frequently occurs in hilly regions like Himalaya, Western and Eastern Ghats. In Tamil Nadu, most of the landslides are often seen in Blue Mountains, Kodaikanal and Yercaud, occasionally in the other areas. Kodaikanal hills are facing two major problems viz. urbanization and environmental degradation. In this study, the landslide hazard zonation maps are prepared based on the causative factors of slope instability, namely lithology, structure, slope morphometry, relative relief, land use and land cover and hydrogeological conditions in facet wise by using BIS code: IS 14496 (Part-2) - 1998. As per BIS classification method in Kodaikanal area, the distribution pattern of Landslide Hazard Zonation (LHZ) indicates that in the total 102 facets, 21 facets come under high hazard category, 39 facets are present in medium hazards and remaining 42 facets come under range in low hazard.
