Abstract
The study of landslides for long time is studied by geomorphological approach. In the study of geomorphology, each and every spatial segment of the earth surface possesses some physiographic aspects. Its analysis enables us to predict an interrelationship between physical and cultural phenomena as a whole. Pacet is one of the most susceptible areas due to landslides in Mojokerto Regency, East Java. Pacet is located at mountainous area which the slope stability depends upon physical and chemical properties of the soil. Such condition is represented on the geomorphic properties, such as slope angle, slope aspect, profile curvature, TWI, TPI, SPI and lithological composition. To obtain a proper landslides susceptibility mapping, some data were derived from geospatial data such as slope angle, slope aspect, profile curvature, TWI, TPI and SPI. DEM extraction by GIS platform were used to obtain the data. Soil samples were collected from different landform unit. The spatial distribution of landslides data was processed using GIS Software. The result shows that landslides were influenced by slope, aspect, profile curvature, TWI, TPI, SPI and lithological composition in study area.
