- Ground-motion model is:
where S

_{j}= 1 for site j and S_{j}= 0 otherwise. - Response parameter is velocity for 0% damping.
- Uses same data as Kamiyama and Yanagisawa (1986).
- Uses same regression method as Kamiyama and Yanagisawa (1986).
- Focal depths between 0 and 130km.
- Uses fault length, L, for 52 records. For others where such data does not exist uses M
_{0}= 10^{(1.5 log 10S+22.3)}, S = 10^{M-4.07}and L = where S is fault area in km^{2}. - Chooses hard slate site with shear-wave velocity of 1–2km∕s as ‘basic site’.
- Does not give coefficients, only graphs of coefficients.
