| This paper reviews the likely source characteristics, focal source mechanism
and fault patterns of the nearest effective seismogenic zones to Greater
Cairo Area. Furthermore, Mmax and ground accelerations related to
the effective seismic events expected in future from those seismogenic zones
are well evaluated. For this purpose, the digital waveform of earthquakes
than ML=3 that occurred in and around Greater Cairo Area from 1997
to 2008 which have been recorded by the Egyptian National Seismological
Network, are used to study source characterization, focal mechanism and fault
pattern of the seismogenic zones around Greater Cairo Area. The ground
motions are predicted from seismogenic zones to assess seismic hazard in the
northeastern part of Greater Cairo, where three effective seismogenic zones,
namely Abou Zabul, southeast Cairo trend and Dahshour area, have the largest
effect to the Greater Cairo Area. The Mmax was determined, based
upon an empirical relationship between the seismic moment and the rupture
length of the fault during the earthquake. The estimated Mmax
expected from Abou Zabul, southeast Cairo trend, Dahshour seismic sources are
of Mw magnitudes equal to 5.4, 5.1, and 6.5, respectively. The
predominant fundamental frequency and soil amplification characteristics at
the area were obtained using boreholes data and in-situ ambient noise
measurement. |
