Ground-motion models are the same as Hong et al. (2009a) (see Section 2.313) for interplate and inslab
Mexican earthquakes and Hong and Goda (2007) and Goda and Hong (2008) (see Section 2.280) for
intraplate Californian earthquakes. Coefficients are: b1= 1.271, b2= 0.337, b3= 0.0, b4= -1.119,
b5= 0.063, h = 5.9, ση= 0.190, σϵ= 0.463, σT= 0.501 and PGAref=exp[1.0 + 0.446(Mw- 7) -0.888ln(rjb2+ 6.32)0.5] for major principal axis and b1= 0.717, b2= 0.454, b3= -0.009, b4= -1.000,
b5= 0.041, h = 5.0, ση= 0.182 (inter-event), σϵ= 0.441 (intra-event), σT= 0.477 (total) and
PGAref=exp[0.532 + 0.518(Mw- 7) - 0.846ln(rjb2+ 5.62)0.5] for minor principal axis for intraplate
California; c1= -3.005, c2= 0.555, c3= -0.00392, c4= 0.0079, ση= 0.106 (inter-event), σϵ= 0.285
(intra-event) and σT= 0.304 (total) for major principal axis and c1= -3.253, c2= 0.575, c3= -0.00380,
c4= 0.0079, ση= 0.121, σϵ= 0.270 (intra-event) and σT= 0.296 (total) for minor principal axis for
inslab Mexican earthquakes; and d1= -0.396, d2= 0.113, d3= -0.00361, d4= 0.0075, d5= 0.474,
d6= -0.0040, ση= 0.193 (inter-event), σϵ= 0.264 (intra-event) and σT= 0.327 (total) for major principal
axis and d1= -0.653, d2= 0.125, d3= -0.00356, d4= 0.0075, d5= 0.474, d6= -0.00177, ση= 0.200
(inter-event), σϵ= 0.273 and σT= 0.339 (total) for minor principal axis for interface Mexican earthquakes.
