  9. 9. 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.

  10. 10. 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.
  11. 11. 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.
