| Outline of Final Research Achievements |
In this study, the characteristics of site amplification in Japan were estimated using the attenuation relationship of each station’s response spectrum. Ground motion records observed during 32 earthquakes were employed to construct the attenuation relationship. The station correction factors were evaluated with respect to the average shear wave velocities averaged over the upper 30 m (AVS30) using a geographic information system dataset. Then, the site amplifications for specific periods were estimated throughout Japan. This study also focused on the seismically induced damage to water distribution pipeline in Sendai City. The inventory of water distribution pipeline and the locations of pipe breaks compiled by the Sendai City Waterworks Bureau were employed in this study. The seismically induced damage to water distribution pipelines concentrated in the hilly residential areas developed with cutting and leveling the hills and then filling the valleys for the past several ten years.
