Insights into the Effect of Source Uncertainties on Ground Motion Simulation of the 2010 Mw7.1 Darfield Earthquake

Abstract

A complete understanding of ground motion uncertainty is fundamental for physics based seismic hazard analysis. This poster focuses on the quantification of the effect of the earthquake source uncertainties (fault geometry, magnitude, etc.) on the ground motion standard deviation. As a case study, the 2010 Mw7.1 Darfield event is examined which not only illustrates a complex fault rupture case but also highlights the amount of non-uniqueness in the earthquake source model.
