The relationships between average shear-wave velocity of the ground and the site amplification factor for peak ground acceleration, peak ground velocity, seismic intensity and response spectral amplitudes are examined by using the strong motion records from the Yokohama Dense Strong-Motion Network. Regarding the amplification factors for peak ground acceleration, peak ground velocity and seismic intensity, the results by the records from smaller magnitude earthquakes and from larger magnitude earthquakes are different. This is due to the different spectral contents of the records from smaller and larger earthquakes. The amplification factors for peak ground acceleration, peak ground velocity and seismic intensity show higher correlations with the average shear-wave velocities of the ground down to 10m, 30m and 20 to 30 m, respectively. The amplification factors for response spectral amplitudes for shorter, mid and longer periods show higher correlations with the average shear-wave velocities of the ground down to 10m, 20m and 30 m, respectively. The correlations of the spectral amplitude at longer period range are higher than those at shorter period range.
