class openquake.hazardlib.gsim.hong_goda_2007.HongGoda2007

Implements GMPE developed for RotD100 ground motion as defined by Hong, H. P. and Goda, K. (2007), “Orientation-Dependent Ground Motion Measure for Seismic Hazard Assessment”, Bull. Seism. Soc. Am. 97(5), 1525 - 1538

This is really an experimental GMPE in which the amplification term is taken directly from Atkinson & Boore (2006) rather than constrained by the records themselves. There may exist a possible units issue as the amplification function for AB2006 is in cm/s/s whereas the GMPE here is given in g

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Horizontal Maximum Direction (RotD100)'

The supported intensity measure component is RotD100

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

The supported intensity measure types are PGA, PGV, and SA

DEFINED_FOR_STANDARD_DEVIATION_TYPES = set(['Total', 'Inter event', 'Intra event'])

The supported standard deviations are total, inter and intra event, see table 4.a, pages 22-23

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Active Shallow Crust'

The supported tectonic region type is active shallow crust

REQUIRES_DISTANCES = set(['rjb'])

The required distance parameter is ‘Joyner-Boore’ distance

REQUIRES_RUPTURE_PARAMETERS = set(['mag'])

The required rupture parameters are magnitude

REQUIRES_SITES_PARAMETERS = set(['vs30'])

The required site parameter is vs30, see equation 1, page 20.

get_mean_and_stddevs(sites, rup, dists, imt, stddev_types)

See superclass method for spec of input and result values.

Implements equation 14 of Hong & Goda (2007)

non_verified = True

GMPE not tested against independent implementation
