class openquake.hazardlib.gsim.convertito_2012.ConvertitoEtAl2012Geysers

Implements the PGA GMPE for Induced Seismicity in the Geysers Geothermal field, published in Convertito, V., Maercklin, N., Sharma, N., and Zollo, A. (2012) From Induced Seismicity to Direct Time-Dependent Seismic Hazard. Bulletin of the Seismological Society of America, 102(6), 2563 - 2573

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Greater of two horizontal'

Supported intensity measure component is the larger of two components

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

Supported intensity measure types are peak ground acceleration

DEFINED_FOR_STANDARD_DEVIATION_TYPES = set(['Total'])

Supported standard deviation types is total.

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Geothermal'

The GMPE is derived from induced earthquakes in the Geysers Geothermal field

REQUIRES_DISTANCES = set(['rhypo'])

Required distance measure is hypocentral distance

REQUIRES_RUPTURE_PARAMETERS = set(['mag'])

Required rupture parameters are magnitude

REQUIRES_SITES_PARAMETERS = set(['vs30'])

Required site parameters. The GMPE was developed for two site conditions “with” and “without” site effect. No information is given regarding the soil conditions, so we assume “with site effect” to correspond to NEHRP Classes C, D or E (i.e. Vs30 < 760), and “without site effect” to corresponse to NEHRP Classes A and B (i.e. Vs30 >= 760)

See superclass method for spec of input and result values.

non_verified = True

GMPE not tested against independent implementation so raise not verified warning
