Dr. Amin Esmail Khalil gave a presentation about his scientific work and insights for future research. He has a PhD in geophysics from Ain Shams University and is currently an Associate Professor of Geophysics at Helwan University. His scientific work includes using seismic methods like AVO analysis and ground motion simulation to study reservoirs in the Nile Delta and assess earthquake hazards. For future research, he proposes applying surface wave methods like HVSR and MASW to detect voids and explore archaeological sites, as well as using seismic hazard assessments and ground motion simulations to evaluate national strategic projects.

10. ABSTRACT
The Pliocene section is considered as a target in the Nile Delta and offshore
Mediterranean. A varying seismic response has been highlighted within the
Neogene succession in the Nile delta central sub-basin, off-shore, the Lower
Pliocene has varying seismic response, in comparison with the Upper Miocene
and Middle to Upper Pliocene sections, although all of these sections are
producing hydrocarbons.
The Lower Pliocene has many turbidity channels, of more than 140 Km2 and
considered as the future of exploration in this area. Hence, a detailed
investigation of the Lower Pliocene reservoirs has been done, compared to
the rest of the Neogene succession. Classical seismic interpretation and AVO
applications may contribute for better understanding for reasons of
difference in the AVO response for the Lower Pliocene section from other
sections.
The sections of the Middle & Upper Pliocene and Upper Miocene are
characterized by gas sands of significant lower acoustic impedance than the
encasing shales, so it gives AVO response of class 3. While the Lower Pliocene
is characterized by gas sands of significant higher acoustic impedance than
the encasing shale, so it gives AVO response of class 1.

15. Ground motion simulation at Bab Zuwayla, Cairo, Egypt
Fatimid Cairo is a one of the most important Islamic compounds in
Egypt. The age of the buildings is up to one thousand year.
Unfortunately many of the building are suffering from huge misuse
that may lead to catastrophe. Many buildings and mosques were
affected by partial and total collapse because of October 12th 1992
Cairo Earthquake. So, damage potential there through assessment of
earthquake hazards has been estimated.
The deterministic and probabilistic methods were used to define the
credible earthquake that represent the maximum expected magnitude
or ground acceleration in the study area). The next step is to use the
stochastic ground motion simulation technique to estimate both the
time history and response spectra at the site of interest.
Based on the analyses, the credible earthquake has the same
epicentral region of Cairo 1992 earthquake but with magnitude of
(6.3). The peak ground acceleration (PGA) is calculated using the
parameters of the credible earthquake. The resultant value is 75
cm/s2. The simulated strong acceleration, on the other hand, yielded
the value of 60 cm/s2. These values are relatively low, however, it may
be dangerous when incorporated with the effects of the soil beneath
the structure and its condition.

16. Strong Motion Simulation At Abu Zenima City, Gulf of Suez, Egypt
Earthquake hazards assessments are important task for the design of
earthquake resistant structures and insurance industry. Such assessments
get more importance when the site of interest is located near an active
earthquake zone. Such situation is present for the location of Abu Zenima
city. The city is characterized by the presence of industrial and Maritime
platform in addition to other Oil production facilities. These industrial
facilities motivated the present work. The simulated earthquake ground
motion time histories are conducted using stochastic technique. The
magnitude used for simulation is obtained using both probilistic and
deterministic approaches. Analysis using both approaches shows that
moderate earthquakes in vicinity of the site could have the largest effects on
the area. Thus an earthquake of magnitude 4.5 at a distance of 21 km is
chosen as design earthquake. The simulated ground motions are presented
in terms of acceleration, velocity, and displacement time histories. In
addition the response spectra are also presented that may be used for
engineering purposes.
