- Ground-motion model is:
where Y is in cm∕s2; when using r

_{epi}: a = 1.0028, b = 0.3330, c = -0.8842, h = 2.4, e = 0.1717 and σ = 0.3574 (for larger), a = 0.8947, b = 0.3410, c = -0.8834, h = 2.6, e = 0.1725 and σ = 0.3428 (for geometric mean) and a = 0.9050, b = 0.3485, c = -1.0803, h = 3.2, e = 0.1596 and σ = 0.3240 (for vertical); and when using r_{hypo}(h is constrained to zero): a = 1.1317, b = 0.3282, c = -0.9297, e = 0.1860 and σ = 0.3680 (for larger), a = 1.0335, b = 0.3365, c = -0.9352, e = 0.1865 and σ = 0.3527 (for geometric mean) and a = 1.0706, b = 0.3430, c = -1.1418, e = 0.1767 and σ = 0.3392 (for vertical). - Uses 2 site classes:
- Rock
- Granite, diorite, gneiss, sandstone, limestone or siltstone. Roughly V
_{s}> 360m∕s. 82 records. S = 0. - Soil
- Alluvium, sand, gravel, clay, sandy clay, silt, sandy silt or fill. 167 records. S = 1.

Cannot use more complex approach because of insufficient information for Chinese sites.

- Selects 129 from China (mainly SMA-1A and GDQJ-1A instruments) and Taiwan and, because there are insufficient to develop model, adds 120 records from Japan.
- Data from China corrected using unknown technique. Data from Japan uncorrected.
- Plot residuals w.r.t. r and M and find no significant trends.
