Liquefaction Potential of Native Ground in West Kobe, Japan by the Spectral Analysis of Surface Waves (SASW) Method

Figure 3

Common source mid-point array for profiling with a 100 kg electro-mechanical shaker. The shaker apparatus allows for controlled-frequency swept sine SASW analysis. Array separation changes from d:2d to d:d to increase the amplitude of the signal received at sensor 2 and 4 for large array separations.
