- Ground-motion model is
^{10}:where Y is in gal, a

_{1}= 0.1497, a_{2}= 1.9088, a_{3}= -2.049, a_{4}= 0.1818 and a_{5}= 0.7072 (σ is unknown). - Use macroseismic intensities and strong-motion data to derive model. Details unknown.
- There is another model by these authors Huo and Hu (1991) (see Section 2.88) to which this model is probably similar.

^{10}In the source for this model (Zhang et al., 1999) there is an additional -2.049M^{2} term but as this is the same coefficient as
the geometric decay term and with this quadratic magnitude term the model predictions very small PGAs it is thought that it is a
typographic mistake.
