Modelling of seismic hazard for the El-Dabaa area, Egypt
Abstract This paper reviews the likely ground acceleration related to a seismic event for the location of a nuclear power site at El-Dabaa, Egypt. More recent data have been integrated into the design philosophy developed some 20 years ago and seismic hazard assessment was carried out using probabilistic techniques. The maximum possible earthquake magnitude Mmax was estimated for the area surrounding El-Dabaa and the hazard parameter peak ground acceleration (PGA) calculated for given zones. The iso-acceleration map of the El-Dabaa area for a return period of 400 years indicates PGA values of 0.15 g, slightly above those for a 100-year return period. The results are in general very similar to those obtained using the deterministic approach of El-Sayed. The differences in some zones may be related to the fact that the probabilistic methods are very sensitive to the completeness of the data and use simple attenuation laws that oversimplify the wave’s propagation phenomena. The work on the estimation of PGAs will contribute to the determination of national seismic codes, giving guidance on which buildings must take seismic risk into consideration and the necessity to re-appraise the seismic risk for existing buildings.
