Ghofrani and Atkinson (2014)

class openquake.hazardlib.gsim.ghofrani_atkinson_2014.GhofraniAtkinson2014[source]

Implements the Subduction Interface GMPE of Ghofrani & Atkinson (2014) for large magnitude earthquakes, based on the Tohoku records. Ghofrani, H. and Atkinson, G. M. (2014) Ground Motion Prediction Equations for Interface Earthquakes of M7 to M9 based on Empirical Data from Japan. Bulletin of Earthquake Engineering, 12, 549 - 571

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Average horizontal'

Supported intensity measure component is assumed to be geometric mean

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 peak ground acceleration, peak ground velocity and spectral acceleration

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

Supported standard deviation types is total.

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Subduction Interface'

The GMPE is derived for subduction interface earthquakes in Japan

REQUIRES_DISTANCES = set(['rrup'])

Required distance measure is rupture distance

REQUIRES_RUPTURE_PARAMETERS = set(['mag'])

Required rupture parameters are magnitude

REQUIRES_SITES_PARAMETERS = set(['backarc', 'vs30'])

The GMPE provides a Vs30-dependent site scaling term and a forearc/ backarc attenuation term
