In the Southern Hyogo prefecture earthquake of 1995,the damaged belt zone of seismic intensity 7 was attracted, in which wooden houses were severely damaged by short period components of seismic motions. It had been said conventionally that short period components were strongly influenced of comparatively shallow structure of soil. However, it became clear that deep structure to a base rock gave influence also from response analysis of strong motion records. After the 1995 earthquake, studies on deep structure of soil have been carried out by many research groups. This research tends to estimate a deep structure of soil in the Nobi plain by using an array measurement of microtremors. The velocities of P wave and S wave and the thickness of soil layers were obtained at the four sites (Owari-asahi, Kanie, Inazawa and Hirata).
