According to the past seismic damage cases, it is in particular clear that the structure on the complicated irregular ground suffered great damage in earthquake. The purpose of this study is to identify the ground structure and the dynamic characteristics of the surface ground by the vertical array earthquake observation records. Earthquake observation has been carried out from 1994 by Tokyo Metropolitan University to acquire the fundamental earthquake data that were necessary for the seismic damage assumption as a part of the disaster prevention planning of Zushi city. In this study, using the earthquake observation records, the surface ground around the observation stations having the inclined bedrock modeled by two-dimensional FEM was identified, and the dynamic characteristics of the ground was investigated. And the dynamic response characteristic of the general irregular ground was considered based on the consequence.
