- Ground-motion model is:
_{1}= 0.14, c_{2}= -6.25, c_{3}= 0.37, c_{4}= 3.67, c_{5}= -12.42, c_{6}= -0.125, c_{7}= 1.19, c_{8}= -6.15, c_{9}= 0.525, c_{10}= -0.16, c_{11}= 18.04, c_{12}= -167.9, c_{13}= 476.3, D_{5}= 0.7, b_{v}= -0.24, V_{A}= 484.5, R_{3}= 100km, σ = 0.83 (given by (Graizer et al., 2010) and reported in text of Graizer et al. (2013)) and σ = 0.55 (Graizer et al., 2013, Figure 6). Coefficients c_{4}, c_{5}, c_{10}–c_{13}and D_{5}are newly derived as is σ — the others are adopted from GMPE of Graizer and Kalkan (2007). D_{3}= 0.65 for Z < 1km and 0.35 for Z ≥ 1km. - Use sediment depth Z to model basin effects.
- Use two faulting mechanisms:
- 1.
- Strike-slip and normal. F = 1.00
- 2.
- Reverse. F = 1.28

- Update of GMPE of Graizer and Kalkan (2007) (see Section 2.278) to model faster attenuation for R > 100km using more data (from the USGS-Atlas global database).
- Compare data binned into 9 magnitude ranges with interval 0.4 and find good match.
- Note that large σ due to variability in Atlas database.
- Using data binned w.r.t. M
_{w}and into 25 distance bins (with spacing of 20km) derive these models for σ: σ = -0.043M + 1.10 and σ = -0.0004R + 0.89. - Examine residual plots w.r.t. distance, M
_{w}and V_{s,30}and find no trends.
