Lebanon is situated in the eastern Mediterranean, an area that is seismically active. In order to understand the effect of geotechnical parameters on the seismic soil response, the paper presents the results of the analysis of five deposits both clayey and sandy with different depths. A detailed study is carried out in order to understand the effect of phreatic level, plasticity index, and input earthquake acceleration on soil response. The amplification is studied both in terms of soil surface acceleration change as well as the ratio of response spectra (RRS). Accelerations measured at the soil surface were as much as five times higher than those measured on the neighboring rock, when rock accelerations were less than 10%g, the amplification factor being less in the presence of sandy soils. Less amplification was observed in the unsaturated deposits, and the ratio of response spectra increased with the plasticity index.
