DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Average Horizontal (RotD50)'

Supported intensity measure component is orientation-independent average horizontal GMRotI50

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

Supported intensity measure types are spectral acceleration, peak ground velocity and peak ground acceleration

DEFINED_FOR_STANDARD_DEVIATION_TYPES = set(['Total', 'Inter event', 'Intra event'])

Supported standard deviation types are inter-event, intra-event and total, see section “Aleatory Variability Model”, page 1094.

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Active Shallow Crust'

Supported tectonic region type is active shallow crust

REQUIRES_DISTANCES = set(['rx', 'rjb', 'rrup'])

Required distance measures are Rrup, Rjb and Rx

REQUIRES_RUPTURE_PARAMETERS = set(['hypo_depth', 'rake', 'width', 'ztor', 'mag', 'dip'])

Required rupture parameters are magnitude, rake, dip, ztor, rupture width and hypocentral depth

REQUIRES_SITES_PARAMETERS = set(['z2pt5', 'vs30'])

Required site parameters are Vs30, Vs30 type (measured or inferred), and depth (km) to the 2.5 km/s shear wave velocity layer (z2pt5)

get_mean_and_stddevs(sites, rup, dists, imt, stddev_types)

See superclass method for spec of input and result values.

get_mean_values(C, sites, rup, dists, a1100)

Returns the mean values for a specific IMT
