We performed 3D ground motion simulations for 9 recent moderate earthquakes in the San Francisco Bay Area to evaluate the USGS SF06 3D velocity model (Brocher et al., 2005; Jachens et al., 2005) in terms of modeling phase arrival timing, peak ground motion amplitudes, and general seismic waveforms. In addition, we performed forward modeling to obtain 3d structure modifications to improve the fit to available data.
