See Douglas (2004), page 72.
N.B. After a comparison with other GMPEs, we reduced the range of the surface-wave magnitude from (3-7.6) to (6-7.6).
Validation:
M = 5.0, d = 10 km : PGA = 433.4029727168 cm/s2
M = 6.0, d = 10 km : PGA = 519.7127976379 cm/s2
M = 5.0, d = 100 km : PGA = 52.967279444744 cm/s2
