The horizontal force transmitted to the turbine and the substructure of a wind power system is very important factor in system safety, and such a system is particularly vulnerable to large-scale coastal disasters such as earthquakes and typhoons. Wind power systems built offshore and on coasts have reduced economic efficiency due to the increase in initial investment costs, because they require a more robust design when installed in areas vulnerable to coastal disasters. The western and southern seas of Korea have a relatively shallow water depth, which is advantageous for the construction of offshore wind farms. However, since it is close to the Pacific Rim, the probability of an earthquake is relatively high compared to those in other regions, and the frequency of typhoons is higher as well, so a more detailed site analysis is necessary. In this study, the GIS technique was used to select an optimal site for wind farms with a focus on reducing the risk of coastal disasters. The current state of earthquakes in the western and southern seas of Korea as well as the movement path and intensity of typhoons affecting or passing through the western and southern seas were also analyzed in a complex manner. As a result, an optimal site for an offshore wind farm with the lowest risk of coastal disasters was analyzed.
