Sadigh et al. Attenuation
In this example, you can calculate several horizontal ground motion parameters at a site using attenuation relationships by Sadigh et al. The relationships for PGA, PGV, and PGD are from Sadigh and Egan, 1998, and the relationships for psuedospectral acceleration are from Sadigh, et al., 1997. Note that the site-to-fault distance is the closest distance to the rupture surface and the relationship is valid over the range of 0 to 100 km only. The valid range of magnitudes is 4 < Mw < 8. Links to tables of coefficients can be found in Appendix A. Interactive examples for all attenuation relationships can be found in Attenuate©.
