| Abstract: | The characteristics of seismic ground motions in southern China are difficult to determine statistically due to a lack of
strong ground motion data. In this study, a stochastic finites-fault ground motion model was adopted to simulate the seismic
ground motions at bedrock for southern China, based on parameters derived from small and medium earthquakes that have occurred
in the region. From these, the response spectra was estimated. A set of ground motion attenuation relationships was then developed
based on simulated peak ground motions and response spectral parameters through regression, which would be applicable for
use in engineering practice. Through comparison, it was demonstrated that the proposed ground motion relationships are generally
consistent with those obtained from other reported ground motion attenuation models for southern China.
