Site effects on peak ground acceleration and velocity observed during the 1987 Chiba-ken-toho-oki earthquake (M=6.7) were evaluated. Strong-motion records at 173 sites with different site conditions were used for the analysis. The results indicate that 1) the site effects are more significant on peak ground velocity than on peak acceleration, 2) geomorphological land classification is more appropriate for evaluating the site effects than soil profile type or surface geology, and 3) the average shear-wave velocity of ground is a useful predictor of ground motion amplification at specific sites.
