SEISMIC HAZARD ASSESSMENT AND SEISMIC SAFTY FOR THE PROPOSED ASTRONOMICAL OBSERVATORIES AT ABU TARTUR AND FAYED SITES, EGYPT

The assessment of seismic hazard for the selected sites was done by delineating the seismic sources in the northern part of Egypt, selecting the controlling earthquake, determining the attenuation models of peak ground acceleration with distance, and finally defining the seismic hazard at the selected site. The soil effect at the site of interest is calculated and introduced to the estimated ground motion. Both of deterministic and probabilistic approaches are used to evaluate the maximum ground motion at both of Abu-Tartur and Fayed sites.
