All Implemented Interfaces:

ConvertsMag, GroundMotionModel

public abstract class AtkinsonBoore_2006
extends Object
implements GroundMotionModel, ConvertsMag

Abstract implementation of the ground motion model for stable continental regions by Atkinson & Boore (2006). This implementation matches that used in the 2008 USGS NSHMP. In addition to have two stress-drop scaling variants, this model also comes in magnitude converting (mb to Mw) flavors to support the 2008 central and eastern US model.

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

Implementation note: this uses a reduced set of frequencies that correspond most closely to defined Imts.

Implementation note: Mean values are clamped per GmmUtils.ceusMeanClip(Imt, double).
