The intensity measure component is the component of interest of ground shaking for an intensity measure.
Usually defined as the geometric average of the maximum of the two horizontal components (which may not occur at the same time).
The geometric mean of the records rotated into the most adverse direction for the structure.
An orientation-independent alternative to AVERAGE_HORIZONTAL. Defined at Boore et al. (2006, Bull. Seism. Soc. Am. 96, 1502-1511) and is used for all the NGA GMPEs.
The largest value obtained from two perpendicular horizontal components.
The horizontal component.
The median horizontal component.
A randomly chosen horizontal component.
An orientation-independent alternative to AVERAGE_HORIZONTAL. Defined at Boore et al. (2006, Bull. Seism. Soc. Am. 96, 1502-1511) and is used for all the NGA GMPEs.
The vertical component.
GSIM standard deviation represents ground shaking variability at a site.
Standard deviation representing ground shaking variability within different events.
Standard deviation representing ground shaking variability within a single event.
Total standard deviation, defined as the square root of the sum of inter- and intra-event squared standard deviations, represents the total ground shaking variability, and is the only one that is used for calculating a probability of intensity exceedance (see openquake.hazardlib.gsim.base.GroundShakingIntensityModel.get_poes()).
