- Ground-motion model is:
where D is rhypo and R is repi, y is in m∕s2, c = 0.38778, α = 0.32927, k = 0.29202, a = 1.557574,
β = 1.537231, γ = 0.027024 and σ = 0.03 (note that this σ is additive).
- All records except one at 13km from distances of 20 to 70km so note that lack information from near field.
- Compare predictions to records from the 2003 Boumerdes (Mw6.8) earthquake and find that it
underpredicts the recorded motions, which note maybe due to local site effects.
