Application of a Hybrid Modeling Method for Generating Synthetic Ground Motions in Fennoscandia, Northern Europe

ABSTRACT We present a modeling technique for generating synthetic ground motions, aimed at earthquakes of design significance critical structures and motions distances corresponding to the engineering near field, in which real data are often missing. use dynamic based on finite-difference approach simulate rupture process within fault, followed by kinematic generate motions. The earthquake source ruptures were modeled using 3D distinct element code (Itasca, 2013). then used complete program Spudich Xu (2002) propagation seismic waves obtain In this work, we demonstrate method covering frequency ranges interests up 25 Hz quantify differences motion generated. compare 30 km with ground-motion prediction equation, synthesizes expected its randomness observations. can be supplement observations field hazard analysis. hybrid one site Fennoscandian Shield, northern Europe.
