All Implemented Interfaces:

GroundMotionModel

public class CampbellBozorgnia_2003
extends Object
implements GroundMotionModel

Implementation of the Campbell & Bozorgnia (2003) ground motion model for shallow earthquakes in active continental crust. In keeping with prior NSHMP implementations of this older model, only soft rock sites are supported (Vs30 = 760 m/s) following specific guidance by the model authors. Longer periods are also not implemented here due to a dependency on Boore, Joyner & Fumal (1997) whose longest period is 2 sec. This implementation also ignores the author's suggestion to use 'uncorrected' PGA values when computing PGA and uses 'corrected' values for both PGA and spectral acceleration.

Note: Direct instantiation of GroundMotionModels is prohibited. Use Gmm.instance(Imt) to retrieve an instance for a desired Imt.
