SEISMIC RISK ANALYSIS OF WESTERN ARABIA

Based on the seismicity and tectonics of the western part of the Arabian Peninsula, a set of potential earthquake sources are identified and the relationships between magnitude and frequency of occurrence are determined. Using available attenuation laws, the individual influences of potential sources are integrated into the probability distribution of maximum annual intensity and peak ground acceleration. The results are presented in the form of seismic risk maps for various return periods, cumulative distribution functions and intensity zone graphs. Based on the results of this study, it is concluded that the seismic hazard potential for the central region is moderate but it is high for the northern and southern provinces.
