Strong Ground Motion Prediction based on 3-Dimensional Non-elastic FEM in Kyoto Basin Area from a Scenario Earthquake of the Hanaore Fault

Abstract

We conduct a three-dimensional earthquake response analysis to evaluate the ground motion in the Kyoto basin from a scenario earthquake of the Hanaore Fault, in order to perform the seismic estimation of important cultural assets in the city. The analysis is based on a non-linear finite element method to calculate the non-elasticity of soil, and considers the multi-input of earthquake motion at the bedrock, and the wave propagation through an irregular underground structure. The results show that it is necessary to consider the source ground motion, wave propagation and soil response at each site simultaneously, for the purpose of the estimating the seismic ground motion on the surface of basin structure like Kyoto.
