The previous presentation described the process of finding landslide susceptibility zonation based on GIS, which contained four parts. Firstly, according to read journals and articles, we applied similar methodology which has been used by some scientists in previous researches or journals to confirm the potential hazard areas and then this presentation indicated what types of areas that are more susceptible to trigger landslide and the scope of our study area. Next, how to divide the different landslide hazard level has been introduced. Lastly, three main criteria such as slope, soil types and water course have been applied to filtrate the highest risk landslide area.
Landslide, defined as the mass movement of rock and one of the devastating geological process.Besides, Landslide as one of the major natural hazards, which causes huge property damage and even the loss of life almost every year in mountainous areas (Rawat et al. 2015; Huabin et al., 2005). For example, the landslide cause 1573 people dead and more than 10000 people injured and 500000 houses ruined in China mountainous areas in 1988(Huabin et al., 2005). Moreover, according to a declaration of United Nations, it is estimated that, landslide cause the economic losses about two to five billions US dollars per year (Schuster, 1994). Hence, there is a need for identification of landslide-prone areas and landslide-prone areas usually defined as a place where the under-soil is unstable and is more susceptible due to external factors such as sub-ground soil type, slope angle, water course and other geomorphology features (Chung and Fabbri, 1995). Also, our study area Adelaide Hill is mountainous area and nearby a lot of watercourse, a lot of houses built in this area and some roads, walk trails go through this area. Therefore, this research report will classify this area in different hazard level and label the highest risk area to prevent local residents and properties from the damage of landslides.
