The effect of topography on the seismic wave-motion has been of interest to many studies. In this study, the earthquake-intensity increments (amplification) on side-zones of valleys within alluvial basins, were investigated using finite element method. A set of finite element models for valleys, one with a triangular cross-section, and the rest with trapezoidal cross-sections, taking into account five different side slopes (17º, 22º, 27º, 37º, 45º), were adapted. The acceleration time-histories obtained through the use of the commercial finite element code (QUAD4M) at valley-sides, valley-edges, and at the intermediate points were transformed to Fourier Amplitude Spectra. The amplitude-frequency variations obtained at the three selected reference points of the valley as well as at the bedrock, were investigated in each of the four selected phases of the earthquake duration. As a result of the performed dynamic analysis, the effect of the valley-slope variation at the three reference points on the valley was examined at four distinct phases of the earthquake duration.
