Abstract
Based on regional seismicity records and seismotectonic conditions, this paper presents a probabilistic assessment of the seismic hazard for the Hong Kong region. The potential seismic source zones are identified and the resultant seismic ground motion parameters evaluated. The pertinent attenuation relations proposed by various authors are analyzed. Uncertainty analyses are also conducted. The main conclusion is that the peak acceleration on bedrock lies is in the range of 75-115gal for the Hong Kong region, corresponding to a 10% probability of exceedence in 50 years. The basic seismic intensity for the same probability of occurrence is rated as VII for the study area.
