- Landslide damage comprise most part of the damages from the earthquake, and it only cause the damage to lives and structures directly, but also cease the operation of social system by road or lifeline failure. For these reasons, hazard assesment on the landslides has been recognized very important. And haard maps have been used to visualize the hazard of the landslide. In this study, as the first step for application of hazard map to domestic cases, hazard maps are made for the Ul-joo, Ul-san, Korea, where the Yang-san faults are located. For building hazard maps the degree of hazard are evaluated assesmentm, maximum ground acceleration obtained from attenuation equation of wave propagation, and design earthquake acceleration suggested by Ministry of construction, are used for acceleration term. Hazard maps are made by GIS programs. Arc/Info and Arc/View, based on the digital maps and data from lab tests and elastic wave surveys. The maps show the possible landslide regions significantly, and the displacements of slide are proportional to the slope angles.
