Chiou and Youngs 2008¶
Implements GMPE developed by Brian S.-J. Chiou and Robert R. Youngs and published as “An NGA Model for the Average Horizontal Component of Peak Ground Motion and Response Spectra” (2008, Earthquake Spectra, Volume 24, No. 1, pages 173-215).
COEFFS= <openquake.hazardlib.gsim.base.CoeffsTable object>¶
Coefficient tables are constructed from values in tables 1, 2 and 3 (pages 197, 198 and 199). Spectral acceleration is defined for damping of 5%, see page 208.
DEFINED_FOR_INTENSITY_MEASURE_COMPONENT= 'Average Horizontal (GMRotI50)'¶
Supported intensity measure component is orientation-independent measure
GMRotI50, see page 174.
DEFINED_FOR_INTENSITY_MEASURE_TYPES= set([<class 'openquake.hazardlib.imt.PGA'>, <class 'openquake.hazardlib.imt.PGV'>, <class 'openquake.hazardlib.imt.SA'>])¶
Supported intensity measure types are spectral acceleration, peak ground velocity and peak ground acceleration, see tables at pages 198 and 199.
DEFINED_FOR_STANDARD_DEVIATION_TYPES= set(['Total', 'Inter event', 'Intra event'])¶
Supported standard deviation types are inter-event, intra-event and total, see chapter “Variance model”.
DEFINED_FOR_TECTONIC_REGION_TYPE= 'Active Shallow Crust'¶
Supported tectonic region type is active shallow crust, see page 174.
REQUIRES_DISTANCES= set(['rx', 'rjb', 'rrup'])¶
Required distance measures are RRup, Rjb and Rx (all are in eq. 13a).
REQUIRES_RUPTURE_PARAMETERS= set(['rake', 'dip', 'ztor', 'mag'])¶
Required rupture parameters are magnitude, rake (eq. 13a and 13b), dip (eq. 13a) and ztor (eq. 13a).
REQUIRES_SITES_PARAMETERS= set(['vs30measured', 'z1pt0', 'vs30'])¶
Required site parameters are Vs30 (eq. 13b), Vs30 measured flag (eq. 20) and Z1.0 (eq. 13b).
