Presents a new empirical ground motion model commonly referred to as attenuation relationship, developed as part of the PEER Next Generation on Attenuation of Ground Motion (NGA) Project. Using a common database of worldwide strong motion recordings, a subset of ground motion data and predictor variables believed appropriate for use in developing the model were selected. Consistent with the requirements of the PEER NGA Project, both a median and aleatory uncertainty model for peak ground acceleration (PGA), peak ground velocity (PGV), peak ground displacement (PGD), and response spectral acceleration (PSA) and displacement (SD) for oscillator periods ranging from g 0.01-10.0 s, magnitudes ranging from 4.0- 8.0, and distances ranging from 0-200 km are developed and considered valid for use in the western United States and similar tectonically active regions of shallow crustal faulting worldwide.
