![]() ![]() The sum total of all ratings for causative intrinsic parameters and external triggering parameters are represented as Evaluated Landslide Hazard (ELH) based on which the study area is divided into classes of hazard zones as per the SSEP rating scheme and the LHZ map of the study area was produced in GIS environment. The intrinsic parameters considered are slope geometry, slope material, structural discontinuities, land use/ land cover and groundwater whereas the external triggering factors are seismicity, rainfall and manmade activities. In applying SSEP rating scheme, the relative contribution of each of the intrinsic causative and extrinsic triggering factors were evaluated and ratings were assigned for each factor facet wise. ![]() For digitizing, data processing, and analysis purposes, Arc-GIS 9.3 and Global Mapper 12 software were used. Field measurements on structural discontinuities and observation on field manifestations for landslide and related slope instabilities was carried out. Remote sensing and field survey was conducted to map the distribution of existing landslides and the factors that affect the landslide occurrences. ![]() The main objective of the study was to prepare the LHZ map of the study area and to derive suitable recommendations based on the results of the study. In the Present study Landslide Hazard Zonation (LHZ) mapping around the route from Alem ketema town to Ambat village was carried out by applying Slope Stability Susceptibility Evaluation Parameter (SSEP) rating scheme. ![]()
