Development of Attenuation Equations of Ground Motions in the Southern Part of the Korean Peninsula

한반도 남부 지역의 지진동 감쇄식 개발

The objective of the study is to develop attenuation equations of groud motions in the southern part of the Korean Peninsula. The earthquake source characteristics and the medium properties were estimated from available instrumental earthquake records and used as input parameters. The peak ground accelerations (PGA) and pseudo-velocty response spectra(PSV) were simulated by the random vibration theory. The attenuation equations for the PGA were constructed in terms of local magnitudes and hypocentral distances.
