Abstract
In this study, statistical features of frequency dependent damping models of SH wave in the subsurface ground are investigated. The damping models are identified from the vertical array observation records installed in the various locational conditions sites.<br> We discussed the appropriateness of damping models estimated from the seismic ground motion data recorded from the dense vertical array observation system located in the typical horizontally-layered ground. The frequency dependent model and the frequency independent model are compared with reference to information criterion. Akaike's information criteria show that the frequency dependent damping model is adequate to explain the observation records.<br> Then, frequency dependent damping models of 29 sites identified from seismic observation data recorded by the vertical array observation system are analyzed statistically. It followed that average damping models grouped by the topographic classifications or the representative S wave velocities are obtained.
