The regional simulations to date have not included local site response effects or soil-structure interaction. These effects are addressed in refined simulations of a portion of a sub-region that includes an idealized threedimensional, horizontally layered soil, along with a simplified model of a building and foundation on the surface. To perform simulations of a sub-region, the Domain Reduction Method (DRM) is used to define the seismic input motion and a mixed explicit-implicit (mE-I) time integration method is used because of the different physics of wave propagation in the soil and vibration of the structure. The simulations involve considerable computational challenges. New parallel computing procedures have been developed for scalable computation. Using an approximately one and one-half million element mesh for the soil region, the preliminary simulation results provide important insights into soil-structure interaction and site response effects.
