抄録

The purpose of this study is to estimate average characteristics of peak acceleration Amax, peak velocity Vmax, and response spectrum SA of strong motions in the near-source region with a wide range of earthquake magnitude. Attenuation relations are estimated by performing regression analysis on strong ground motions, which composed of records in California, Mexico and Chile, earthquake magnitude M of 5.9 to 7.9, and source-to site distance X of 4 km to about 300 km. Equivarent hypocentral distance Xeq is used in the regression analysis as X in order to take into account the effect of fault extension in the near-source region. The estimated regression coefficients are generally coincident with the results of the other studies on atteniation relation of strong motions including near-source data. It is found that Amax, Vmax and SA do not show the strong dependencies on M, when X are normalized by assumed fault radius R.
