class openquake.hazardlib.gsim.boore_1993.BooreEtAl1993GSCBest[source]

Implement equation used by the Geological Survey of Canada (GSC) for the 2010 Western Canada National Seismic Hazard Model. The class implements the model of David M. Boore, William B. Joyner, and Thomas E. Fumal (“Estimation of Response Spectra and Peak Accelerations from Western North American Earthquakes: An Interim Report”, 1993, U.S. Geological Survey, Open File Report 93-509). Equation coefficients provided by GSC for the random horizontal component and corresponding to the ‘Best’ case (that is mean unaffected)

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Random horizontal'

Supported intensity measure component is random horizontal RANDOM_HORIZONTAL,

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

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

DEFINED_FOR_STANDARD_DEVIATION_TYPES = set(['Total'])

Supported standard deviation type is total

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Active Shallow Crust'

Supported tectonic region type is active shallow crust, given that the equations have been derived for Western North America

REQUIRES_DISTANCES = set(['rjb'])

Required distance measure is Rjb distance see paragraph ‘Predictor Variables’, page 6.

REQUIRES_RUPTURE_PARAMETERS = set(['mag'])

Required rupture parameter is magnitude

REQUIRES_SITES_PARAMETERS = set([])

site params are not required
