영어 초록

In low to moderate seismic regions, there are limited earthquake ground motion data recorded from past earthquakes. In this regard, th e Gyeongju earthquake (M=5.8)occurred on September 12, 2016 produces valuable information on ground motions. Ground motions w ere recorded at various recording stations located widely in Korean peninsula. Without actual recoded ground motions, it is impossible t o make a ground motion prediction model. In this study, a point source model is constructed to accurately simulate ground motions rec orded at different stations located on different soil conditions during the Gyeongju earthquake. Using the model, ground motions are ge nerated at all grid locations of Korean peninsula. Each grid size has 0.1°(latitude)x0.1°(longitude). Then a contour hazard map is constr ucted using the peak ground acceleration of the simulated ground motions
