Numerical Site Spectral Amplification Due to Structural Control of Shallow Faults in Wadi Natash, Eastern Desert, Egypt

Abstract

Recently, studies by [2] and [3] have focused on analyzing the site effects due to the presence of fault zones. Ground motion amplification of directional effects along a polarized horizontal component could be observed because of active faults and extended fractures (e.g. [4]). Directionality effects are observed as variations in horizontal amplifications versus fault zone azimuths ([5], [6], and [7]), indicating anisotropy of Swave velocity (i.e. high S-wave velocities are parallel to the fault zone, whereas the low
