MODEL APPLICABILITY
The model developed in this study is considered to be applicable for estimation pseudo
spectral accelerations (5% damping) for earthquakes in active tectonic regions in which the
following conditions apply:
4 ≤ M ≤ 8.5 for strike-slip earthquakes
4 ≤ M ≤ 8.0 for reverse and normal faulting earthquakes
0 ≤ RRUP ≤ 200 km
150 ≤ VS30 ≤ 1500.
The model was developed using the anelastic attenuation parameter γ constrained by data
from California earthquakes. For application in other regions where distances greater than
about 50 km are a major contributor to the hazard, the adjustments to the γ parameter may be
warranted and can be performed using the hybrid approach developed by Campbell (2003).
