“…The activity that takes place near the southern tip of Sinai has no definite trend. According to Korrat et al (2005), this phenomenon is related to thermal activity and the triple junction nature of that area, Arabian and African plates and Sinai subplate. The motion along these boundaries creates seismic activity of small to large magnitude.…”

“…The focal depths of almost all earthquakes observed are in ranges mainly deeper than the other zones which ranged from 30 km to 70 km. The maximum observed magnitude was 5.1 near to Safaga (Korrat et al 2005).…”

“…3). These boundaries are formed in two trends; the Red Sea-Gulf of Suez-Cairo-Alexandria trend and the Gulf of Aqaba-Dead Sea trend (Maamoun et al 1984;Kebeasy 1990;Cochran 2005;Korrat et al 2005;Dahy 2010). …”

“…Magnitude Mw = 7.3 on November 22, 1995, was the largest earthquake occur along the Dead Sea Transform at the end of the last century. The focal depths of almost all earthquakes observed range mainly from 5 to 25 km (Hamouda 2000;Korrat et al 2005). The third zone (Triple Junction) is characterized by three earthquake swarms seen at Shadwan, Gubal Islands (at the entrance of the Gulf of Suez), and the southern tip of Sinai Peninsula (Ras Mohamed).…”

The entrance of the southern Suez Gulf of the Red Sea is known to be an area of high seismic activity in Egypt. The high rate of seismic activity in this area is mainly related to the adjustment in motion at the triple junction between the African plate, the Arabian plate, and the Sinai microplate. The present study attempts to estimate the Probabilistic Seismic Hazard Analysis (PSHA) for Hurghada site. This was done in two steps; the first one is by estimating specific parameters for the site, such as the mean seismic activity, k, the Gutenberg-Richter parameter, b, and the maximum regional magnitude, m max . The second step is by selecting a ground motion parameter that is applicable to Hurghada site. The procedure permits the combination of both historical and recent instrumental data. The results of the hazard assessment, expressed as the worst case scenario, detect that Hurghada is exposed to the maximum credible earthquake event of magnitude m max = 7.

“…The activity also defines an active trend extending from the southern tip of the Sinai Peninsula to the median zone of the Red Sea. The seismicity of this trend is probably related to the active spreading zone associated with the opening of the Red Sea (Korrat et al, 2006). Previous crustal structural results (Dorre et al, 1997;Saleh et al, 2006) evaluated the extreme oceanic crustal structures which are flooring the axial trough of the northern Red Sea rift and 30-38 km thick continental crust underneath the Dead Sea rift.…”
