Model Description

Model Form

• This model produces the cumulative absolute velocity at specified locations for given magnitude and hypocenter location of several earthquake sources as input , based on the Du-Wang (2012) attenuation relation.
• Depth of each earthquake is predicted based on the magnitude.
• For more information, see Du-Wang (2012).

DDM Sensitivities

• No

Properties

Object Name

• Name of the object in Rt
• Allowable characters are upper-case and lower-case letters, numbers, and underscore (“_”).
• The name is unique and case-sensitive.

Display Output

• Determines whether the model is allowed to print messages to the Output Pane.

Magnitude List

• Magnitudes of various earthquake sources

Hypocentre Location List

• Hypocenter locations of earthquake sources, which automatically will yield the radius \({R}\) to the various output locations.

Interevent Sigma

• Inter-event model error, typically a standard normal random variable

Intraevent Sigma

• Intra-event model error, typically a standard normal random variable

Fault Type

• Fault mechanism that can either be Unspecified, Normal, ReverseOblique, or Reverse.

Response Type

• Type of the response is \({CAV}\).

Structure Location List

• List of the locations where the intensity will be computed at them (the output will give as many intensity values as the locations provided here)

Site Class

• Site class that can either be UnspecifiedClass, SGSSiteClassC, SGSSiteClassD.

H and C1 to C8 Uncertainty

• The uncertainty in attenuation relation coefficients represented by Standard Normal random variables.

Output

• Earthquake intensities (as many as the locations provided in the input)
• The output is an automatically generated generic response object, which takes the object name of the model plus “Response”.
