Abstract

The Next Generation Attenuation (NGA) East project has an updated database for Central and Eastern North America (CENA) ground motions. I analyzed the performance of ground motion prediction equations (GMPEs) used in the United States Geological Survey (USGS) National Seismic Hazard Mapping Project (NSHMP) and other potential GMPEs used in the CENA through bias analysis, model inadequacies check using statistical tests and finally ranking the GMPEs using log likelihood (LLH), and the Euclidean Distance Based Ranking (EDR) technique. From bias analysis, Atkinson and Boore (2011) (model A08p), Atkinson and Boore (2011) (model AB06p), and Atkinson and Boore (2006) (model AB06+) with 200 bar stress drop performed better than other GMPEs. EDR results show models A08, AB06p, and AB06+ as the best performing models for combined site classes. Models AB06p, EPRI (2004) cluster2 model (EPRI2), AB06+ and Silva et al. (2002) (SD02) matched the data well in rock sites.
