Ground Motion Simulation Validation (GMSV) Technical Activity Group (TAG)

SCEC has established this TAG focused on GMSV in order 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.
