Implements GMPE developed by T. Allen and published as “Stochastic ground- motion prediction equations for southeastern Australian earthquakes using updated source and attenuation parameters”, 2012, Geoscience Australia Record 2012/69.

COEFFS_DEEP = <openquake.hazardlib.gsim.base.CoeffsTable object>

Coefficients for deep events taken from Excel file produced by Trevor Allen and provided by Geoscience Australia (20120821.GMPE_coeffs.xls) (coefficients in the original report are not correct)

COEFFS_SHALLOW = <openquake.hazardlib.gsim.base.CoeffsTable object>

Coefficients for shallow events taken from Excel file produced by Trevor Allen and provided by Geoscience Australia (20120821.GMPE_coeffs.xls) (coefficients in the original report are not correct)

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Median horizontal'

Supported intensity measure component is the median horizontal component see table 7, page 35

DEFINED_FOR_INTENSITY_MEASURE_TYPES = set([<class 'openquake.hazardlib.imt.SA'>, <class 'openquake.hazardlib.imt.PGA'>])

Supported intensity measure types is spectral acceleration, see table 7, page 35, and PGA (coefficients assumed to be the same of SA(0.01))

DEFINED_FOR_STANDARD_DEVIATION_TYPES = set(['Total'])

Supported standard deviation type is only total, see table 7, page 35

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Stable Shallow Crust'

Supported tectonic region type is stable continental crust

REQUIRES_DISTANCES = set(['rrup'])

Required distance measure is closest distance to rupture, see paragraph ‘Regression of Model Coefficients’, page 32

REQUIRES_RUPTURE_PARAMETERS = set(['hypo_depth', 'mag'])

Required rupture parameters are magnitude and hypocentral depth, see paragraph ‘Regression of Model Coefficients’, page 32 and tables 7 and 8, pages 35, 36

REQUIRES_SITES_PARAMETERS = set([])

No site parameters are needed, the GMPE is calibrated for average South East Australia site conditions (assumed consistent to Vs30 = 820 m/s) see paragraph ‘Executive Summary’, page VII
