Package: nga
Description: This package implements the earthquake ground motion
prediction equations developed as part of the Next Generation
Attenuation of Ground Motions (NGA) project coordinated by the
Pacific Earthquake Engineering Research Center (PEER) in 2008.
The models implemented in this package are AS08 (Abrahamson &
Silva, 2008), BA08 (Boore & Atkinson, 2008), CB08 (Campbell &
Bozorgnia, 2008), and CY08 (Chiou & Youngs, 2008).  This
numerical implementation has been validated by comparing the
results for 128,000 test cases against the results obtained
using the Fortran implementation composed by David M. Boore and
Kenneth W. Campbell.  Users are encouraged to view U.S.
Geological Survey Open-File Report 1296, entitled
"Implementation of the Next Generation Attenuation (NGA)
Ground-Motion Prediction Equations in Fortran and R," by J.
Kaklamanos, D. M. Boore, E. M. Thompson, and K. W. Campbell
(2010) for further details on these programs.  More details
