gov.usgs.earthquake.nshmp.gmm.AbrahamsonSilva_1997

All Implemented Interfaces:

GroundMotionModel

public class AbrahamsonSilva_1997
extends Object
implements GroundMotionModel

Implementation of the Abrahamson & Silva (1997) 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).

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