SEISMOLOGICAL INVESTIGATION AT MEKAAD RADWAN OTTOMAN PERIOD- CAIRO-EGYPT (a)

Earthquakes are generally considered the most dangerous factor affecting the historicalbuildings. The present study is focusing on the determination of the effects of earthquakeactivities on the historical site of Mekaad Radwan Compound near outskirt of old FatimidCairo, the area of Bab Zwiela "Bawabat El Metwali". The analysis of the seismicity dataaround the site under investigation is carried out to define the design or credible earthquake.In order to achieve the scientific, practical works; seismotectonics, Simulation of earthquakeground motion in the site and site response are studied. The deterministic and probabilisticapproaches were carried out showing that the credible earthquake may be located at thesame seismic zone of Cairo 1992 earthquake.
