This objective of this project is to validate long-period ground motion site amplification associated with basin effects as provided by three-dimensional numerical simulations. Site effects are evaluated from mixed effects residuals analyses, as described for example in Stewart et al. (2017). The simulations are performed for source conditions (location and earthquake size) for which ample recordings are available. This allows site effects in basins to be evaluated in a consistent manner from recorded data and from simulations. The project team was coordinated under the Ground Motion Simulation Validation (GMSV) group within SCEC and include: Chukwuebuka Nweke (UCLA), Jonathan Stewart (UCLA), Scott Brandenberg (UCLA), Robert Graves (USGS), Christine Goulet (USC).
