class openquake.hazardlib.gsim.hong_goda_2007.HongGoda2007[source]

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.PGA'>, <class 'openquake.hazardlib.imt.PGV'>, <class 'openquake.hazardlib.imt.SA'>])

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


The supported tectonic region type is active shallow crust


The required distance parameter is ‘Joyner-Boore’ distance


The required rupture parameters are magnitude


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

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
