GIS-based spatial prediction of landslide susceptibility using frequency ratio model of Lachung River basin, North Sikkim, India

View Original View Raw

Summary

This article examines two different models to assess landslide susceptibility in two different areas. The first model is a GIS-based spatial prediction of landslide susceptibility using the frequency ratio model in the Lachung River basin of North Sikkim, India. The second model is an information value and logistic regression model which was used in the Goncha Siso Eneses area of northwestern Ethiopia. The results of both models were compared and discussed in order to provide a better understanding of landslide susceptibility in the two regions.
