Edwards and Fah 2013 Alpine

class openquake.hazardlib.gsim.edwards_fah_2013a.EdwardsFah2013Alpine10Bars

This function implements the GMPE developed by Ben Edwars and Donath Fah and published as “A Stochastic Ground-Motion Model for Switzerland” Bulletin of the Seismological Society of America, Vol. 103, No. 1, pp. 78–98, February 2013. The GMPE was parametrized by Carlo Cauzzi to be implemented in OpenQuake. This class implements the equations for ‘Alpine’ and ‘Foreland - two tectonic regionalizations defined for the Switzerland - therefore this GMPE is region specific”. @ implemented by laurentiu.danciu@sed.ethz.zh

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Average horizontal'

Supported intensity measure component is the geometric mean of two horizontal components AVERAGE_HORIZONTAL

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, and peak ground acceleration, see tables 3 and 4, pages 227 and 228.

DEFINED_FOR_STANDARD_DEVIATION_TYPES = set(['Total'])

Supported standard deviation type is total, Carlo Cauzzi - Personal Communication

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Active Shallow Crust'

Supported tectonic region type is ALPINE which is a sub-region of Active Shallow Crust.

M1 = 5.0

Fixed magnitude terms

REQUIRES_DISTANCES = set(['rrup'])

Required distance measure is Rrup

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

Required rupture parameters: magnitude

REQUIRES_SITES_PARAMETERS = set(['vs30'])

Required site parameter is only Vs30 (used to distinguish rock and deep soil).

ROCK_VS30 = 1105

Vs30 value representing typical rock conditions in Switzerland. confirmed by the Swiss GMPE group
