Abstract

The Red Sea rift zone is an area of medium to high seismic hazard, with many medium and large magnitude earthquake recorded historically and very recently. On the other hand, the shoreline in South Sinai and on the Egyptian mainland has undergone unprecedented development with tens of new mini- towns and tourist resorts. Detailed and verified seismic design criteria and sample input motion have not been derived before this important area In this paper, all available historical and instrumental records of earthquake activity are reviewed, and a definitive catalogue assembled. Conventional probabilistic seismic hazard analysis was undertaken, whilst ensuring the homogeneity of the data used. Levels of ground motion for seismic design are derived as a function of probability of being exceeded, and for different return period
