Abstract: Accurate modeling of earthquake ground motion is important for reduction of earthquake disasters. In this study, we developed a heterogeneous high-fidelity 3D model with low order FEM, which is pointed out to be more accurate than previously exploited methods. We then performed a verification test and an application example targeting maximum frequency of 1.0 Hz to confirm the proposed method.

Keywords: earthquake ground motion modeling, high-fidelity 3D FEM model, hybrid MPI and Open MP parallel computation
