Scholarcy highlights

  • The landslide inventory details were mapped out using high resolution satellite image, the data collected from secondary sources and field investigation
  • landslide susceptibility zonation maps were generated by calculating relationship between the landslide influencing factors with training landslide data in the case of frequency ratio model but for analytical hierarchy process model pair-wise comparison were made to derive the weights and final score
  • The Area Under Curve value of frequency ratio model is 0.8157 showing better prediction accuracy than the analytical hierarchy process model
