BergeThierryEtAl2003SIGMA
[source]¶ Implements GMPE developed by Catherine Berge-Thierry, Fabrice Cotton, Oona Scoti, Daphne-Anne Griot-Pommera, and Yoshimitsu Fukushima and published as “New Empirical Response Spectral Attenuation Laws For Moderate European Earthquakes” (2003, Journal of Earthquake Engineering, 193-222) The class implements also adjustment of the sigma value as required by the SIGMA project to make the GMPE usable with Mw (the GMPE was originally developed for Ms).

COEFFS
= <openquake.hazardlib.gsim.base.CoeffsTable object>¶ Coefficient tables are constructed from the electronic suplements of the original paper. Original coefficients in function of frequency.
-
DEFINED_FOR_INTENSITY_MEASURE_COMPONENT
= 'Horizontal'¶ Supported intensity measure component is horizontal, see page 196.
-
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. The original manuscript provide coefficients only SA. For PGA, coefficients are assumed equal to the ones of SA for the smallest period (0.03 s)
-
DEFINED_FOR_STANDARD_DEVIATION_TYPES
= set(['Total'])¶ Supported standard deviation type is total, see table 3, page 203
-
DEFINED_FOR_TECTONIC_REGION_TYPE
= 'Active Shallow Crust'¶ Supported tectonic region type is active shallow crust, see Introduction, page 194.
-
REQUIRES_DISTANCES
= set(['rhypo'])¶ Required distance measure is hypocentral distance, see equation 1 page 201
-
REQUIRES_RUPTURE_PARAMETERS
= set(['mag'])¶ Required rupture parameters is magnitude, see equation 1 page 201
-
REQUIRES_SITES_PARAMETERS
= set(['vs30'])¶ Required site parameters is Vs30, used to distinguish between rock sites (Vs30 >= 800) m/s and alluvium sites (300 < Vs < 800), see section 2.2.3 page 201
