| | Abstract | | Earthquake damages occurred by the earthquake that occurred at the Middle West of Tottori in 1983 , 2002 and the 2000 Western Tottori earthquake in the central part of Tottori Prefecture. It is supposed that the damage influenced the subsurface structure. It is important that the information of subsurface structures is obtained for prediction of ground motion in the area. Microtremor and gravity surveys were carried out in the plains of the shore part and Kurayoshi city area. S-wave velocity models are obtained at the array observation 3 sites and predominant period distribution at 3-components observation 84 sites newly. The gravity anomalies were obtained by gravity survey data at 80 sites newly. |
