| | Abstract | | We study spectral amplification of ground motion by using microtremor data observed in Chiba Prefecture. To examine the ground amplification characteristic in detail, and to evaluate it, we carry out array and point observation of microtremor in whole of Chiba Prefecture and improve the velocity model which is made by Chiba Prefecture, by using the technique of Senna and Midorikawa, in which microtremor data, such as H/V spectral ratio is used. |
