Potential landslide assessment of changwat Phuket

Abstract

The landslide assessment has been undertaken using the influencing parameters of geology including rock types and lineament zone, landform including slope gradient and elevation, surface drainage zone, land use and land cover, soil characteristics, and rainfall intensity. The relationship between these parameters and the spatial data are evaluated using the proposed weight-rating technique. Finally, the landslide potential map has been prepared against the socio-economic and physical environmental setting of the Phuket Island. Different degrees of susceptibility to landslide have been evaluated and illustrated in the landslide potential map. The findings of the present study reveal that most of the potential areas to be affected by very high and high susceptibility to landslide include the famous tourist resorts.
