並列タイトル等Estimation of S-wave Velocity Structure of Tsuruga Plain Based on Microtremor Observation
一般注記The accurate estimations of Quaternary structure are indispensable in order to accurately predict the seismic damage of the region. However, around the Tsuruga Plain, subsurface investigation infonnation such as the S-wave velocity structure hardly exists. The problems analyzed in this study are estimations of 3D Quaternary configuration of the Tsuruga Plain using the data from microtremor observations. Microtremor array observations have been conducted at twelve sites in order to determine the S-wave velocity structure. The phase velocities at each site were inverted to a vertical S-wave profile using a genetic algorithm. To interpolate the array observations, the 3-components microtremor observations were carried out at 58 points. The 3D configuration models of Quaternary have been evaluated by using geo-statistical procedure. By comparing with the inverted structure of gravity anomaly observation and with the existing data, the validity of the estimated structure was examined.
