Abstract

ABSTRACT
Sinai Peninsula has a triangular shape between the African and Arabian Plates and bounded from the western and eastern borders by the Gulf of Suez and Gulf of Aqaba-Dead Sea rift systems, respectively. It has been affected by strong and destructive earthquakes, and moderate earthquakes through its history. Due to the damage distributions observed during these earthquakes, it became necessary to construct the seismic mapping for Sinai based on the available data (including SPT and CPT results) that have been collected from site investigations of some locations. The factors of safety against liquefaction for some locations in Sinai are accurately computed in this work conducted herein this paper. This paper presents an important contribution for constructing a map for Sinai representing the minimum safety factors against liquefaction and hence the liquefaction susceptibility. It is concluded that, Sharm El-Sheikh zone located at the southern tip of Sinai generally represents the most critical zone in Sinai, regarding the seismicity effect in case a high seismic local magnitude (M=7.2) is applied.
