- Ground-motion models are, for interface:
where Y is in cm∕s2, c

_{1}= 2.594, c_{2}= 0.112, c_{3}= -0.0037, c_{5}= 0.0075, c_{6}= 0.474, c_{7}= -0.0033, σ_{e}= 0.20 (inter-event), σ_{r}= 0.27 (intra-event) and σ = 0.33 (total) for maximum response; c_{1}= 2.545, c_{2}= 0.108, c_{3}= -0.0037, c_{5}= 0.0075, c_{6}= 0.474, c_{7}= -0.0024, σ_{e}= 0.20 (inter-event), σ_{r}= 0.27 (intra-event); σ_{c}= 0.10 (random-orientation variability) and σ = 0.35 (total) for geometric mean; and, for inslab:_{1}= -0.014, c_{2}= 0.562, c_{3}= -0.0039, c_{5}= 0.0071, σ_{e}= 0.10, σ_{r}= 0.28 and σ = 0.30 for maximum response; and c_{1}= -0.109, c_{2}= 0.569, c_{3}= -0.0039, c_{5}= 0.0070, σ_{e}= 0.10, σ_{r}= 0.28, σ_{c}= 0.07 and σ = 0.30 for geometric mean. - All data from firm soil sites (NEHRP class B).
- Similar analysis to that of Hong and Goda (2007) (see Section 2.279) concerning orientation of major response axis but for data from Mexican subduction zone.
- Use data of García et al. (2005) (see Section 2.238) for inslab earthquakes.
- Focal depths, H, for interplate earthquakes are between 8 and 29km and depths for inslab earthquakes are between 35 and 138km.
- Examine correlation of ratio of response along an arbitrary direction to the maximum response in direction of major axis w.r.t. dependent and independent parameters and find that as an approximation there is no dependency.
- Provide statistical models to describe the ratio of response along an arbitrary direction to the maximum response in direction of major axis.
- Term expressing magnitude-dependency of decay (i.e. 1.82 - 0.16M
_{w}) taken from previous study as is near-source saturation term (i.e. 0.0075 × 10^{0.507Mw}).
