Project Abstract
 This SCEC funding provided travel support for the PI to attend the 2013 SCEC annual meeting to present on-going work related to broadband ground motion simulations of the 2010-2011 Canterbury earthquakes. This project is a multi-institutional effort with researchers from New Zealand and the USA (Rob Graves, USGS, and Brady Cox, UTexas, Austin), and has benefited greatly from interaction with SCEC researchers.
Intellectual Merit The developed 3D velocity model makes use of numerous high quality datasets, and is the first such model developed for the region, and in fact NZ. This project is part of on-going work to simulate ground motions from the 2010-2011 Canterbury earthquakes, and addresses the GMSV and EERI SCEC objectives.
