The micro topographical features and the surface ground structures are greatly involved in the earthquake damage of structures. Recently, the microtremor array observation can be used for the setimation of soil structure. In this paper, we performed the microtremor array observation by the SPAC method at three kinds of different ground condition sites, soft ground condition, medium ground condition and hard ground condition, and we compared the experimental dispersion curve with the theoretical dispersion curve by using soil structure model evaluated from boring data. Then, we investigated the utility of microtremor array observation method.
