| Research Abstract |
The purpose of this study is development of real-time and quasi real-time evaluation methods of long-period ground motion, in order for earthquake damage reduction, rapid damage estimation, and quick response. A strong-motion database is constructed for the Tohoku region, Japan. The real-time estimation method of S-wave amplitudes at far stations from P-wave amplitudes at near-source stations is developed. Also, the method to estimate distribution of response spectra is developed based on spatial interpolation on seismic bedrock and amplification by deep underground structure. The applicability of these methods is confirmed for the 2005 Miyagi-oki earthquake.
