Landslides Hazard Map in Malay Peninsula by Using Historical Landslide Database and Related Information

摘要

Recently, slope disaster has occurred in regions around urban area and along highways in Malay Peninsula. The disaster is a major factor that disturbs the sustainable development in the country. It is important to understand high potential regions of landslide and to predict slope disaster based on geotechnical and geological engineering for a sustainable development. Historical data of slope disaster helps us to understand the regional characteristics of landslide and the mechanism. The purpose of this study is to develop a historical landslide database in Malay Peninsula. The database can be available on GIS. The developed historical landslide database has been used with related information to landslide on GIS for investigation of characteristics of landslide in Malay Peninsula. In order to evaluate the hazard of slope failure in the whole Malay Peninsula, the spatial relationships between locations of historical landslides and the related information with slope failure have been investigated. Finally, the locations of historical landslide events are plotted on the proposed hazard map for confirming the applicability.
