In Japan, many types of landslides exist and occur. Deep-seated landslide GIS maps have been completed thoughout Japan. In addition, many GIS data on geology and topography such as 10m_DEM are provided by several government, such as Geological Survey of Japan and Geographical Survey Instiute, Japan. Therefore, it is possible to analyze the relationship between the deep-seated landslides and geology and the other factors.
While, heavy rainfalls and earthquakes have been triggering shallow landslides in many places. I have been analyzing relationship between these landslides and topography such as slope degrees etc.

From both of the results for deep-seated landslides and shallow landslides, I am trying to make susceptibility maps of the landslides.
