| Abstract: | Landslide susceptibility map delineates
the potential zones for landslides occurrence. The
paper presents a statistical approach through spatial
data analysis in GIS for landslide susceptibility
mapping in parts of Sikkim Himalaya. Six important
causative factors for landslide occurrences were
selected and corresponding thematic data layers were
prepared in GIS. Topographic maps, satellite image,
field data and published maps constitute the input
data for thematic layer preparation. Numerical
weights for different categories of these factors were
determined based on a statistical approach and the
weighted thematic layers were integrated in GIS
environment to generate the landslide susceptibility
map of the area. The landslide susceptibility map
classifies the area into five different landslide
susceptible zones i.e., very high, high, moderate, low
and very low. This map was validated using the
existing landslide distribution in the area. |
