Project Abstract
 At the 2010 SCEC Annual Meeting, SCEC established a Technical Activity Group (TAG) focused on Ground Motion Simulation Validation (GMSV). The purpose of this TAG is to develop and implement, via collaboration between ground motion modelers and engineering users, testing/rating methodologies for simulated ground motions to be used in engineering applications. An initial planning workshop held in January of 2011 resulted in recommendations for initial efforts to be undertaken by the GMSV TAG. Building on these recommendations, the subsequent GMSV Plenary Session at the 2011 SCEC Annual Meeting resulted in identification of six priority activities/topics for the 2012 SCEC Science Collaboration Plan. As stipulated there, any Principal Investigators funded to work on GMSV-related projects were to become members of the GMSV TAG who would be required to coordinate with each other.

To coordinate and discuss the seven GMSV-related SCEC projects funded in 2012, two workshops were convened via this award. The first workshop (in April 2012) coordinated the seven projects before they began in earnest, and also resulted in a discussion of what would become the SCEC Broadband Platform Validation Project. The second workshop (at the 2012 SCEC Annual Meeting) shared progress on some of the 2012 GMSV-related SCEC projects, the Broadband Platform Validation Project, and other GMSV projects. Feedback was obtained on these projects and on priority activities/topics for the 2013 SCEC Science Collaboration Plan. It is important to note that each of the two workshops included participation from both ground motion modelers and engineering users.
Intellectual Merit The SCEC Ground Motion Simulation Validation (GMSV) Technical Activity Group (TAG) and the workshops convened via this award contribute to advancing the prediction of strong ground motions (SCEC research objective "6"). More specifically, the workshops have enabled the GMSV TAG to make progress towards defining testing/rating methodologies for simulated ground motions to be used in engineering applications.
Broader Impacts The SCEC Ground Motion Simulations Validation (GMSV) Technical Activity Group (TAG) and the workshops convened via this award have brought together engineering users of simulated ground motions, from research and practice, with SCEC scientists who model them. In doing so, the workshops contribute to the impact of SCEC in mitigating seismic risks to society, whether via earthquake risk assessment, building codes, or other engineering efforts.
