Implements GMPE developed by Sinnan Akkar and Zehra Cagnan and published as “A Local Ground-Motion Predictive Model for Turkey, and Its Comparison with Other Regional and Global Ground-Motion Models” (2010, Bulletin of the Seismological Society of America, Volume 100, No. 6, pages 2978-2995). It extends openquake.hazardlib.gsim.boore_atkinson_2008.BooreAtkinson2008 because the linear and non-linear site effects are described by the same site response function used in Boore and Atkinson 2008.

COEFFS_AC10 = <openquake.hazardlib.gsim.base.CoeffsTable object at 0x2adf8a000850>

Coefficient table (from Table 3, p. 2985) sigma is the ‘intra-event’ standard deviation, while tau is the ‘inter-event’ standard deviation

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Average horizontal'

Supported intensity measure component is geometric mean of two horizontal components : attr:~openquake.hazardlib.const.IMC.AVERAGE_HORIZONTAL, see paragraph ‘Functional Form’, p. 2981.

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

Supported intensity measure types are spectral acceleration, peak ground velocity and peak ground acceleration, see paragraph

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

Supported standard deviation types are inter-event, intra-event and total, see Table 3, p. 2985.

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Active Shallow Crust'

Supported tectonic region type is active shallow crust (the equations being developed for Turkey, see paragraph ‘Strong Motion Databank’, p. 2981)

REQUIRES_DISTANCES = set(['rjb'])

Required distance measure is Rjb. See paragraph ‘Functional Form’, p. 2981.

REQUIRES_RUPTURE_PARAMETERS = set(['rake', 'mag'])

Required rupture parameters are magnitude, and rake. See paragraph ‘Functional Form’, p. 2981.

REQUIRES_SITES_PARAMETERS = set(['vs30'])

Required site parameters is Vs30. See paragraph ‘Functionl Form’, p. 2981.
