Action Items

  • This year: Finish implementation of the selected ground-motion parameters (GMP's) and their empirical ground-motion models (GMM's) in the Broadband Platform (BBP).
  • This year: For the newly-implemented GMP's, make use of the comparisons between simulated and recorded ground motions and empirical GMM's that were developed by the BBP Validation Study for elastic pseudo spectral acceleration.
  • This year: Post Python codes for the newly-implemented GMP's and previously-developed BBP comparison plots and tables on the GMSV TAG wiki.
  • This year: Convene a workshop to demonstrate use of the newly-implemented GMP's to compare simulated and recorded ground motions and (newly-implemented) empirical GMM's.
  • Next year: Consider implementing additional GMP's, e.g., pulse period and amplitude, and a combination of peak ground velocity and peak ground displacement.
  • Next year: Consider implementing revisions to the Anderson GOF parameter(s) that quantify whether simulated ground motions are larger or smaller than recorded ground motions.
  • Next year: Develop new comparisons of simulated and recorded ground motions and empirical GMM's, e.g., using Bayesian Model Selection.
