3S-aided landslide hazard monitoring and modeling

According to internal and external factors of landslide hazard, it demonstrates the logical framework of the landslide hazard system. New contents are explored in relation to 3S technology applied to landslide harzard research. It is possible to extract hazard backgrounds timely and fast by combining traditional methodology and 3S technology. Classification of landslide modeling methodology is discussed and analyzed. The function of 3S technology in landslide hazard modeling is presented. Determinacy model and risk assessment are discussed in details.
