Abstract:
In Nefas-Mewcha to Weldiya road corridor (study area), landslide incidence resulted in the
death of people, devastation of infrastructure, properties, crops, and agricultural lands. To reduce damages
due to landslide incidences, a complete landslide susceptibility mapping was carried out using GIS-based
index of entropy (IOE) and frequency ratio (FR)
models. Detailed fieldwork and google earth imagery
analysis were used to identify 712 landslides. These
landslides were divided into two categories: 498
(70%) for modeling and 214 (30%) for model validation. The spatial relationship between pre-existing
landslides and 12 landslide factors was performed.
Using a raster calculator, the weighted landslide factors were combined to provide a landslide susceptibility index (LSI). The natural break classification
