| Abstract: | A probabilistic seismic hazard analysis (PSHA) was conducted to establish the hazard spectra for a site located at Dubai Creek
on the west coast of the United Arab Emirates (UAE). The PSHA considered all the seismogenic sources that affect the site,
including plate boundaries such as the Makran subduction zone, the Zagros fold-thrust region and the transition fault system
between them; and local crustal faults in UAE. PSHA indicated that local faults dominate the hazard. The peak ground acceleration
(PGA) for the 475-year return period spectrum is 0.17 g and 0.33 g for the 2,475-year return period spectrum. The hazard spectra
are then employed to establish rock ground motions using the spectral matching technique. |
