Model Description

Model Form

• This model produces the spectral acceleration, peak ground acceleration, or peak ground velocity at specified locations for given magnitude and hypocentre location of several earthquake sources as input, based on the Boore-Atkinson (2008) attenuation relation.
• Depth of each earthquake is predicted based on the magnitude.
• For more information, see Boore-Atkinson (2008).

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

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

Epsilon Uncertainty List

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

Eta Uncertainty List

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

Fault Types

• Fault mechanism that can be either Unspecified, Normal-slip, Strike-slip, or Reverse-slip

Response Type

• Type of the response than can be either \({S_a}\), \({PGA}\), or \({PGV}\)

Smoothness

• “Smoothed” option will smooth the kinks in the model and the “Original” option will use the model as it is.

Period List

• List of the natural periods at which the intensity is evaluated

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)

Shear Wave Velocity List

• List of the shear wave velocities at the specified locations

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”.
