class openquake.hazardlib.gsim.rietbrock_2013.RietbrockEtAl2013SelfSimilar[source]

Implements the ground motion prediction equation of Rietbrock et al (2013):

Rietbrock, A., Strasser, F., Edwards, B. (2013) A Stochastic Earthquake Ground-Motion Prediction Model for the United Kingdom. Bulletin of the Seismological Society of America, 103(1), 57 -77

The GMPE is derived for the United Kingdom, a low seismicity region. Consequently ground motions are generated via numerical simulations using a stochastic point-source model, calibrated with parameters derived from local weak-motion data. This implementation applies to the case when stress drop is considered to be self-similar (i.e. independent of magnitude).

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Average horizontal'

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

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

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

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

Supported standard deviation types are inter-event, intra-event and total

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Stable Shallow Crust'

Supported tectonic region type is stabe continental crust,

REQUIRES_DISTANCES = set(['rjb'])

Required distance measure is Rjb

REQUIRES_RUPTURE_PARAMETERS = set(['mag'])

Required rupture parameters are magnitude

REQUIRES_SITES_PARAMETERS = set([])

No site parameter is required

class openquake.hazardlib.gsim.rietbrock_2013.RietbrockEtAl2013MagDependent[source]

Implements the Rietbrock et al (2013) GMPE for the case in which the stress parameter is magnitude-dependent (Table 6, Page 65)
