COMPARISON OF SIMULATIONS AND GMPES Jennifer L Donahue, PhD, PE Senior Engineer Geosyntec Consultants SWUS Ground Motion – Workshop 2 SSHAC Level III 22 October 2013

Agenda • Are the three methods similar and how do they compare

to the GMPEs? • How well is the magnitude scaling constrained? • Overview of simulations and GMPEs
