This paper describes the improvement to a fault-to-site analysis tool for use in a fully HPC-enhanced physics-based urban earthquake response analysis. We developed a three-step procedure, involving coarse and refined partitioning for the preprocessing stage, that achieves good balance in computational load and FE nodes used in communications. An end-to-end approach to computing in K computer was also implemented. The results of strong- and weak-scaling tests validate the capability of the tool for application to dynamic analysis involving billions of unknowns. In application to reproduction of observed ground motions, improvements in solution in comparison with previously conducted validations were obtained. The tool was also used to generate synthetic ground motions for analyzing the response of thousands of buildings in an urban area due to a scenario earthquake.
