Geomatrix 1993¶

class
openquake.hazardlib.gsim.geomatrix_1993.
Geomatrix1993SSlabNSHMP2008
[source]¶ 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intraslab events developed by Geomatrix Consultants, Inc., 1993, “Seismic margin earthquake for the Trojan site: Final unpublished report prepared for Portland General Electric Trojan Nuclear Plant”, Ranier, Oregon.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
getGeom
in thehazgridXnga2.f
Fortran 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.PGA'>, <class 'openquake.hazardlib.imt.SA'>])¶ Supported intensity measure types are spectral acceleration, and peak ground acceleration

DEFINED_FOR_STANDARD_DEVIATION_TYPES
= set(['Total'])¶ Supported standard deviation type is only total.

DEFINED_FOR_TECTONIC_REGION_TYPE
= 'Subduction IntraSlab'¶ Supported tectonic region type is subduction intraslab

REQUIRES_DISTANCES
= set(['rrup'])¶ 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

REQUIRES_SITES_PARAMETERS
= set([])¶ No site parameters required

get_mean_and_stddevs
(sites, rup, dists, imt, stddev_types)[source]¶ See
superclass method
for spec of input and result values.
