class openquake.hazardlib.gsim.atkinson_macias_2009.AtkinsonMacias2009

Implements the Subduction Interface GMPE of Atkinson & Macias (2009) for large interface earthquakes in the Cascadia subduction zone. Atkinson, G. M. and Macias, M. (2009) “Predicted Ground Motions for Great Interface Earthquakes in the Cascadia Subduction Zone”, Bulletin of the Seismological Society of America, 99(3), 1552 - 1578

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Random horizontal'

Supported intensity measure component is assumed to be equivalent to the random horizontal component

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

Supported intensity measure types are peak ground acceleration and Spectral Acceleration

DEFINED_FOR_STANDARD_DEVIATION_TYPES = set(['Total'])

Supported standard deviation types is total.

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Subduction Interface'

The GMPE is derived for subduction interface earthquakes in Cascadia

REQUIRES_DISTANCES = set(['rrup'])

Required distance measure is rupture distance

REQUIRES_RUPTURE_PARAMETERS = set(['mag'])

Required rupture parameters are magnitude

REQUIRES_SITES_PARAMETERS = set([])

No required site parameters, the GMPE is derived for B/C site conditions
