Implements GMPE developed by P. Somerville, R. Graves, N. Collins, S. G. Song, S. Ni, and P. Cummins for Non-Cratonic Australia published in “Source and Ground Motion Models for Australian Earthquakes”, Report to Geoscience Australia (2009).

COEFFS = <openquake.hazardlib.gsim.base.CoeffsTable object at 0x2adf8a962dd0>

Coefficients taken from table 3

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Average horizontal'

The supported intensity measure component is set to ‘average horizontal’, however the original paper does not report this information

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

The supported intensity measure types are PGA, PGV, and SA, see table 3

DEFINED_FOR_STANDARD_DEVIATION_TYPES = set(['Total'])

The supported standard deviations is total, see tables 3

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Stable Shallow Crust'

The supported tectonic region type is stable continental region

REQUIRES_DISTANCES = set(['rjb'])

The required distance parameter is ‘Joyner-Boore’ distance, see table 2

REQUIRES_RUPTURE_PARAMETERS = set(['mag'])

The required rupture parameter is magnitude, see table 2

REQUIRES_SITES_PARAMETERS = set([])

no site parameters are defined, the GMPE is calibrated for Vs30 = 865 m/s

get_mean_and_stddevs(sites, rup, dists, imt, stddev_types)[source]

See superclass method for spec of input and result values.

Implement equations as defined in table 2.

Implements GMPE developed by P. Somerville, R. Graves, N. Collins, S. G. Song, S. Ni, and P. Cummins for Yilgarn Craton published in “Source and Ground Motion Models for Australian Earthquakes”, Report to Geoscience Australia (2009). Document available at: http://www.ga.gov.au/cedda/publications/193?yp=2009

Extends openquake.hazardlib.gsim.somerville_2009.SomervilleEtAl2009NonCratonic because the same functional form is used, only the coefficents differ.
