In the past decade the derivation and use of GMPEs within seismic hazard assessments have undergone significant improvements but there remain challenges in ground-motion prediction.
This presentation will provide an overview of recent developments which include: improvements in the estimation of the ground-motion variability and its components; a move away from simple regression-based curve fitting; attempts at using non-parametric techniques; the use of much more and better (e.g. in terms of site characterization) data; attempts at including additional independent parameters; a better appreciation of epistemic uncertainty; extensions of spectral models to shorter and longer structural periods using individually-processed records; a more careful consideration of how the models perform at small and large magnitudes; and making the models easier to use within seismic hazard assessments.
Finally, the presenter will provide his viewpoint on possible future directions in ground-motion estimation.
Non-members of the society are welcome to attend.
