This study is completed to find the relationship of the soil material properties with the earthquake amplification effect on the soil slope geometry using finite difference program FLAC and MatLab. The relationship is conducted throughout two approach models elastic and Mohr Coulomb. The first simulation attempt was completed to determine the most significant model approach. For the input data, acceleration signal Acc base= 3.5464 m/s 2 and different values of the soil parameters shear and bulk modulus, gives the acceleration amplification on the slope geometry as output data. The results indicates that the Mohr Coulomb model is the more precise approach that gives more accurate results and therefore a realistic deign. Following the MC approach, further studies were made concerning the most effective soil parameters. The first simulation done following the MC approach is varying C and phi at fixed height. The result of this study was showed that the slope favors low C values and high phi values. The second simulation, varying c and phi along different heights. The result found in this simulation proved the result already found in the previous simulation that the granular soil is the one favored in slopes stability. In addition to that, the clayey soil dissipates the EQ energy along the height, whereas the granular soil dissipate this energy from the bottom. The last simulation done, the variation of G along heights, showed that the control G is not favored is one of the dominant parameters in soil slope stability.
