public class WC1994_MagAreaRelationship
extends MagAreaRelationship

Title:WC1994_MagAreaRelationship
Description: This implements the Wells and Coppersmith (1994, Bull. Seism. Soc. Am., pages 974-2002) magnitude versus rupture area relationships. The values are a function of rake. Setting the rake to Double.NaN causes their "All" rupture-types to be applied (and this is the default value for rake). Note that the standard deviation for area as a function of mag is given for log(area) (base-10) not area.

Method Summary

double	getAreaStdDev() Computes the standard deviation of log(area) (base-10) from magnitude (for the previously set or default rake)
double	getMagStdDev() Gives the standard deviation for the magnitude as a function of area (for the previously set or default rake).
double	getMedianArea(double mag) Computes the median rupture area from magnitude (for the previously set or default rake).
double	getMedianMag(double area) Computes the median magnitude from rupture area (for the previously set or default rake).
String	getName() Returns the name of the object
void	setRake(double rake) This overides the parent method to allow a value of Double.NaN (which is used to designate the "All" rupture-types option here).

Constructor Detail

WC1994_MagAreaRelationship

public WC1994_MagAreaRelationship()

no-argument constructor. All this does is set the rake to Double.NaN (as the default)

Method Detail

getMedianMag

public double getMedianMag(double area)

Computes the median magnitude from rupture area (for the previously set or default rake). Note that thier "All" case is applied if rake=Double.NaN.

Specified by:

getMedianMag in class MagAreaRelationship

Parameters:

area - in km

Returns:

median magnitude

getMagStdDev

public double getMagStdDev()

Gives the standard deviation for the magnitude as a function of area (for the previously set or default rake). Note that thier "All" case is applied if rake=Double.NaN

Specified by:

getMagStdDev in class MagAreaRelationship

Parameters:

area - in km

Returns:

standard deviation

getMedianArea

public double getMedianArea(double mag)

Computes the median rupture area from magnitude (for the previously set or default rake). Note that thier "All" case is applied if rake=Double.NaN

Specified by:

getMedianArea in class MagAreaRelationship

Parameters:

mag - - moment magnitude

Returns:

median area in km

getAreaStdDev

public double getAreaStdDev()

Computes the standard deviation of log(area) (base-10) from magnitude (for the previously set or default rake)

Specified by:

getAreaStdDev in class MagAreaRelationship

Parameters:

mag - - moment magnitude

rake - in degrees

Returns:

standard deviation

setRake

public void setRake(double rake)

This overides the parent method to allow a value of Double.NaN (which is used to designate the "All" rupture-types option here).

Overrides:

setRake in class MagScalingRelationship

Parameters:

rake -

getName

public String getName()

Returns the name of the object
