This was one of the presentations at PEER's NGA-East Working Meeting on Finite-Fault Simulations that was held at UC Berkeley on December 11, 2012. The purpose of this meeting was to provide a progress update and discussion on finite-fault simulation validation exercise (Task E). Various modelers presented preliminary results of validation as well as the limitations and issues encountered so far. Results include validation against A. scenario events (Loma Prieta, Northridge, Whittier and Saguenay) and B. NGA-West1 GMPEs (2008).
The objective of NGA-East is to develop a new ground motion characterization (GMC) model for the Central and Eastern North-American (CENA) region. The GMC model consists in a set of new ground motion prediction equations (GMPEs) for median and standard deviation of ground motions (GMs) and their associated weights in the logic-trees for use in probabilistic seismic hazard analyses (PSHA).
