Identification analyses for a shear wave velocity profile of a subsurface soil deposit, which were carried out at the H12 site of the strong motion observation system "KASSEM", are presented in this paper. The transfer functions derived from the recorded earthquake ground motions due to 4 different earthquake events are adopted as the target functions. A microtremor measurement also was conducted at the same site. The frequency amplification functions determined based on the identified shear wave velocity profiles are compared with the spectral amplitude ratio of a microtremor, the ratio of the horizontal component of Fourier amplitude spectrum to the vertical one. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
