Class ToroEtAl_1997

java.lang.Object

gov.usgs.earthquake.nshmp.gmm.ToroEtAl_1997

All Implemented Interfaces:

GroundMotionModel

public abstract class ToroEtAl_1997
extends Object
implements GroundMotionModel

Implementation of the Toro et al. (1997) ground motion model for stable continental regions with 2002 updates. This implementation matches that used in the 2008 USGS NSHMP and comes in two flavors (mb and Mw) 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: Mean values are clamped per GmmUtils.ceusMeanClip(Imt, double).
