- Ground-motion model is:
where A(DE,H,S,T) = A

_{0}(T)log Δ(DE,H,M), Δ = (DE^{2}+ H^{2}+ S^{2})^{}, H is focal depth, p is the confidence level, s is from site classification (details not given in paper) and v is component direction (details not given in paper although probably v = 0 for horizontal direction and v = 1 for vertical direction). - Response parameter is pseudo-acceleration for unknown damping level.
- Use same data and weighting method as Monguilner et al. (2000a) (see Section 2.179).
- Find A
_{0}(T) by regression of the Fourier amplitude spectra of the strong-motion records. - Estimate fault area, S, using log S = M
_{s}+ 8.13 - 0.6667log(σΔσ∕μ). - Equation only valid for M
_{min}≤ M ≤ M_{max}where M_{min}= -b_{2}∕(2b_{5}(T)) and M_{max}= -(1 + b_{2}(T))∕(2b_{5}(T)). For M < M_{min}use M for second term and M = M_{min}elsewhere. For M > M_{max}use M = M_{max}everywhere. - Examine residuals, ϵ(T) = log S
_{A}(T) - log S_{A}′(T) where S_{A}′(T) is the observed pseudo-acceleration and fit to the normal probability distribution,

p(ϵ,T) = ∫ exp[-(x - μ(T))∕σ(T)]^{2}∕(σ(T)), to find μ(T) and σ(T). Find that the residuals fit the theoretical probably distribution at the 5% level using the χ^{2}and KS^{7}tests. - Do not give coefficients, only graphs of coefficients.

^{7}Probably this is Kolmogorov-Smirnov.
