Seismic arrays were deployed to study the causes of spatial variation of high-frequency seismic motions in geologically different three sites; paleozoic rock, dilivium, and alluvium. Comparison was made for the spectral ratios and the cross-correlation coeffcients between the sites and the following conclusions are obtained. Sediments contribute the waveform variation above 3 Hz and the spectral ratios in the alluvial site considerably change within the array due to the irregularity of the alluvium and dilivium boundary and the horizontal inhomogeniety in the alluvium. キーワード(英): - 記事区分 - 区分    委員会論文集
