class openquake.hazardlib.gsim.lin_2009.Lin2009[source]

Implements GMPE developed by Po-Shen Lin and published as “Ground-motion attenuation relationship and path-effect study using Taiwan Data set” (Ph.D. dissertation of National Central University, Taiwan). This class implements the equations for ‘crustal events’.

COEFFS = <openquake.hazardlib.gsim.base.CoeffsTable object at 0x2b94af4e9c90>

Coefficient table for rock sites, see table 3 page 227.

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Average horizontal'

Supported intensity measure component is geometric mean of two horizontal components, see equation 4.1 page 46.

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 4.1 in pages 48-49.

DEFINED_FOR_STANDARD_DEVIATION_TYPES = set(['Total'])

Supported standard deviation types is total, see equation 4.1 page 46.

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Active Shallow Crust'

Supported tectonic region type is active shallow crust.

REQUIRES_DISTANCES = set(['rrup'])

Required distance measure is rupture distance, see equation 4.1 page 46.

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

Required rupture parameters are magnitude and rake see equation 4.1 page 46.

REQUIRES_SITES_PARAMETERS = set(['vs30'])

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