| 内容記述 | The seismic records from 52 stations of the seismic network deployed in Miyazaki Prefecture, Japan, arecurrently used to grasp the distribution of seismic intensity of the prefecture immediately after the occurrence of an earthquake. However, the number of instruments may not be large enough to capture the detailed intensity distribution. Hence, microtremor measurements were conducted to estimate site response characteristics of the seismic stations and other locations. The horizontal-to-vertical （H/V） Fourier spectral ratios were calculated for seismic records and microtremor. In some stations having geological survey data, the transfer functions for S-wave and H/V amplitude ratio of Rayleigh wave were also calculated. Comparing all these functions, possibility is suggested that the H/V spectral ratio of microtremor can be used as a quasi-transfer function to predict the seismic motion at the location without instruments. | |||||
