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
Supported intensity measure component is the larger of two components
Supported intensity measure types are peak ground acceleration
Supported standard deviation types is total.
The GMPE is derived from induced earthquakes in the Geysers Geothermal field
Required distance measure is hypocentral distance
Required rupture parameters are magnitude
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.
GMPE not tested against independent implementation so raise not verified warning
