Title : Site specific probabilistic seismic hazard for New Mallawy, Egypt
Abstract:
The common practice of conducting seismic hazard analysis for already built cities can be considered of sub-optimal value. The best practice is the hazard evaluation before the urban planning of the cities. The hazard model used in the current study is based on up-to-date database of historical and recent earthquakes. The site response is accounted for through the use of average 30-m shear-wave velocity (Vs30). A set of Ground motion prediction models is selected to characterize the expected ground motion and associated uncertainty. Epistemic uncertainty in earthquake recurrence, maximum expected earthquake size, ground motion prediction models is considered in the hazard calculations.
Observed variability of earthquake shaking is mainly related to lateral changes in soil properties. The expected earthquake loads are rather low compared to the Egyptian code. The obtained seismic hazard results can be used for urban planning and risk mitigation at the New Mallawy city.
