Seismic Hazard Assessment of the Red Sea Region
The established new catalogue has been used to assess the seismic hazard along the coasts of the Red Sea using the probabilistic approach. Peak ground acceleration caused by earthquakes is mapped for exposure time 50, 100 and 200 years at the 90% probability level of non-exceedance using the SEISRISKIII software. The area involved covered a wide region bounded by latitudes 9º-33º north and longitudes 27º-50º east. The input parameters used for the computations of hazard were obtained from the recent catalogue of the Red Sea region. The catalogue covered the time period 827-2006 with the homogenous moment magnitude (Mw). Attenuation relation of the Red Sea region is not existing, so the attenuation relation of Joyner and Boore 1981 was used. The results are presented in Seismic hazard maps in terms of peak ground acceleration. High hazard values are obtained in the rifted region and its surroundings, Afar and Yemen region and amount to 1.6 cm/Sec. Relatively lower hazard values are attained in highly populated areas, and amounted to 0.2 cm/Sec.
