public final class Wald_MMI_Calc
extends Object

Title: Wald_MMI_Calc

Description: This computes MMI (from PGA and PGV) using the relationship given by Wald et al. (1999, Earthquake Spectra, vol 15, p 557-564). The code is a modified version of what Bruce Worden sent me (Ned) on 12/04/03. This code has been validated against some of the values listed in the USGS on-line data archive for the Puente Hills event: http://www.trinet.org/shake/Puente_Hills_se/download/grid.xyz.zip
