Microtremor measurements are conducted in the Sumiyoshi area, Kobe city, using array of sensors together with conventional measurements using one station. The F-k and H/V spectral analyses of micro-tremors result in two-dimensional shear wave structure down to the bedrock. The distribution of peak ground motions during the 1995 Hyogoken-Nanbu earthquake is then estimated using one-dimensional effective stress analyses. The estimated values in the heavily damaged area are larger than those in the other area, indicating that one-dimensional site amplification characteristics had a significant effect on the damage distribution of buildings.
