Probabilistic seismic hazard assessment of egypt

Zusammenfassung

In the present study, a probabilistic seismic hazard assessment for Egypt is carried out in terms of peak ground acceleration (PGA) and spectral acceleration (SA) values. Hazard curves, uniform and design hazard spectra, and deaggregation results for the most important cities, are also presented, focused on improving the current earthquake engineering knowledge in the region. Seismic hazard computations in terms of PGA and SA values, for both rock and stiff-soil site conditions, with 39.3%, 10% and 5% probability of exceedance in 50 years (return periods of 100, 475 and 975 years, respectively) were performed. Hazard curves and uniform hazard spectra for thirty-one cities in Egypt were computed and plotted against the PGA values considered in the most recent Egyptian building codes (e.g., ECP-201, 2011).
