In an area that has potential for earthquake has possibility of losing soil stability and causing physical soil damage, one of them is liquefaction. This research was conducted to determine the magnitude of deformation on slopes with potentially liquefaction. The soil slope samples were tested using shaking table with various slope and frequency was set. Research began with soil physical properties had unit weight of density 1.81 gr/cm3, moisture content 2.31%, specific gravity 2.72, sand properties with Cu is 2.1, Cc is 0.98 and angle of repose is 23.962°. By giving certain earthquake acceleration in the soil slope sample that was tested by shaking table, it was liquefaction occurred. Results of research, the greater slope and frequency given, so the lateral and axial deformation will increase. Minimum lateral deformation occurs at frequency 6.6 Hz with a slope 6° and maximum lateral deformation is 17 cm at frequency 9.5 Hz with slope 24°, while minimum axial deformation is 0.5 cm at frequency 8 Hz with slope 6° and maximum axial deformation is 5 cm at frequency 9.5 Hz with a slope 24°, but 12-degree slope can consider as a safe slope for slope which holding vibration.
