The ground vibration propagated from the foundation of the large scale shaking table was measured. The main measurement was done in the range of 600 m distance from the foundation to the shaking direction and 200m distance to the direction perpendicular to it. Using shock wave or sinusoidal wave as the input to the shaking table, the frequency response, the relation of the amplitude and the distance dependant on frequency, and the propagation of shock wave were obtained. It was found from this measurement that the ground vibration was extremely sensitive for frequency and distance, the growth of vibration near the foundation was remarkable, and the propagation velocity of the ground vibration was much faster than the S-wave velocity of the surface layer.
