SPATIAL VARIATION IN GROUND MOTION RECORDS FROM THE CHI-CHI, TAIWAN EARTHQUAKE DUE TO RUPTURE DIRECTIVITY EFFECTS

| 抄録（英）： |
Rupture directivity effects feature spatial amplitude variation of near-field ground motion records. Capturing this phenomenon from major earthquakes recorded by recently developed strong-motion networks leads to improvement of existing ground motion attenuation relations. In this study the characteristics of the near-fault strong ground motion in the 1999 Chi-Chi, Taiwan earthquake (Mw=7.6), which recorded by the Seismological Center of Central Weather Bureau of Taiwan (CWB), are investigated. An empirical spectral amplification factor representing the directivity effects for the dip-slip faulting system is developed using the Somerville et al. 1997 directivity model. The obtained results can be easily implemented in seismic hazard assessment studies.
