Abstract
The aim of this paper is to investigate landslide prone areas in Nilgiri hills which have caused damage to people and properties and to devise preventive steps to be taken in the events of future landslides. Our study area was situated at Ooty region, Nilgiri District, Tamilnadu. In this study we use the seismic refraction survey carried out across landslides located near the villages in Allanchi, Kundha, The 2D electrical resistivity imaging (ERI) surveys are acquired near the villages of katerri, Kunda. Topographic models of landslide surface are made for all three sites. Seismic and resistivity imaging method give detailed of the soil, lithomorphic clay and weathered gnessic rocks in the study area. In the study area there are two types of landslides; thin soil slides, and lesser rock mass slides. Landsliding in the study area can be caused by high rainfall and seismic activity. This case study focuses on paleo slides and look at predicting areas of future landslide in Ooty area. Key words: Landslide, seismic refraction, 2D electrical resistivity imaging (ERI), resistivity, Ooty.
