Implements GMPE for subduction intraslab events developed by Geomatrix Consultants, Inc., 1993, “Seismic margin earthquake for the Trojan site: Final unpublished report prepared for Portland General Electric Trojan Nuclear Plant”, Ranier, Oregon.
This class implements the equation as coded in the subroutine
hazgridXnga2.fFortran code available at: http://earthquake.usgs.gov/hazards/products/conterminous/2008/software/
Coefficients are given for the B/C site conditions.
COEFFS= <openquake.hazardlib.gsim.base.CoeffsTable object>¶
Coefficient table obtained from coefficient arrays and variables defined in subroutine getGeom in hazgridXnga2.f
DEFINED_FOR_INTENSITY_MEASURE_COMPONENT= 'Average horizontal'¶
Supported intensity measure component is the geometric mean of two horizontal components
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
Supported standard deviation type is only total.
DEFINED_FOR_TECTONIC_REGION_TYPE= 'Subduction IntraSlab'¶
Supported tectonic region type is subduction intraslab
Required distance measure is rrup (closest distance to rupture)
REQUIRES_RUPTURE_PARAMETERS= set(['ztor', 'mag'])¶
Required rupture parameters are magnitude and top of rupture depth
No site parameters required
