Implements GMPE developed by Shahram Pezeshk, Arash Zandieh and Behrooz Tavakoli. Published as “Hybrid Empirical Ground-Motion Prediction Equations for Eastern North America Using NGA Models and Updated Seismological Parameters”, 2011, Bulletin of the Seismological Society of America, vol. 101, no. 4, 1859 - 1870.

COEFFS = <openquake.hazardlib.gsim.base.CoeffsTable object at 0x2b94b07b7b50>

Equation coefficients, described in Table 2 on pp. 1865

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Average Horizontal (GMRotI50)'

Geometric mean determined from the fiftieth percentile values of the geometric means computed for all nonredundant rotation angles and all periods less than the maximum useable period, independent of sensor orientation. See page 1864. :attr:’~openquake.hazardlib.const.IMC.GMRotI50’.

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. See Table 2 in page 1865

DEFINED_FOR_STANDARD_DEVIATION_TYPES = set(['Total'])

Supported standard deviation types is total. See equation 6 and 7, page 1866.

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Stable Shallow Crust'

Supported tectonic region type is ‘stable continental region’ equation has been derived from data from Eastern North America (ENA)

REQUIRES_DISTANCES = set(['rrup'])

Required distance measure is RRup, explained in page 1864 (eq. 2 page 1861, eq. 5 page 1866).

REQUIRES_RUPTURE_PARAMETERS = set(['mag'])

Required rupture parameters are magnitude (eq. 4, page 1866).

REQUIRES_SITES_PARAMETERS = set([])

No site parameters are needed. The GMPE was developed for hard-rock site

get_mean_and_stddevs(sites, rup, dists, imt, stddev_types)[source]
