Description
It is well known that structures can be damaged by earthquake shaking caused by the rapid rupture of the fault, which releases the stored energy that can result in significant loss of life and property. For economical and hazard aspects, the general seismological laboratory, seismology department, NRIAG, made the first step of hazard mitigation and vulnerability of buildings and structures by constructing the Egyptian Strong Motion Network (ESMN), trying to get a better understanding of structure vulnerability in urban areas in Egypt. The primary goal of this study is to define hazard zones within the urban areas to assess structural vulnerability. Analysis was carried out using 2023 earthquake data. In 2023, Egypt was struck by about one hundred thirty earthquakes in the magnitude range (3.5–7.9) with different epicentral distances (30–900 km). Using peak ground acceleration in terms of magnitude, source to site distance, tectonic environment, and source type has been a key research area in seismic hazard estimation studies for attenuation of earthquakes (Sharma 2000). The primary results showed that the values of PGA are not just affected and decreased by epicentral distances but are mainly dependent on site effects and local amplification.
