Modeling of the Subsurface Structure From the Seismic Bedrock To the Ground Surface for a Broadband Strong Motion Evaluation
Abstract eng: We have collected a lot of boring exploration and physical property data (mainly microtremor observation ones) in the past, which are important to especially evaluate seismic ground motion in period range from 0.5 s to 2.0 s, and have studied combining a shallow part with a deep one on a subsurface structure model, for the purpose of modeling subsurface structure so that we can evaluate broadband earthquake ground motion from 0.1 Hz to 10 Hz. In this paper, we will report the methods of modeling initial subsurface structure and S-wave velocity structure which incorporate period and amplification characteristics based on earthquake and microtremor observation records, in the whole area of Kanto including Tokyo, Japan.
