@Beta
public class Atkinson_2010
extends Object
implements GroundMotionModel

Implementation of the ground motion model by Atkinson (2010) for shallow and deep earthquakes in Hawaii. This model applies a Hawaii specific correction factor to BooreAtkinson_2008.

Note:August 15, 2020 email from Gail Atkinson confirms that shallow event model is about 0.05 log units lower than what is shown in Figure 7 of the reference publication. At short periods, this model and BooreAtkinson_2008 should be the same.

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

Method Details

imt

public Imt imt()

Description copied from interface: GroundMotionModel

The intensity measure type (IMT) of this GMM instance.

Specified by:

imt in interface GroundMotionModel

calc

public LogicTree<GroundMotion> calc(GmmInput in)

Description copied from interface: GroundMotionModel

Computes a logic tree of scalar ground motions and standard deviations for the supplied arguments. This method is implemented by GMMs to provide the horizontal peak ground acceleration and (optionally) velocity (PGA, PGV) as well as 5% damped pseudo-spectral acceleration for periods between 0.01 s and 10 s. For most modern GMMs, ground motions are computed as the average horizontal component (RotD50) but many older GMMs use some other average horizontal measure (e.g. GMRotI50).

Specified by:

calc in interface GroundMotionModel

Parameters:

in - a ground motion model input argument container
