How much radial distance should be considered when preparing an earthquake catalogue for Probabilistic seismic hazard analysis? What is the reason behind consideration of that distance? Is there any particular formula or standard distance?
While there are other influencing factors (e.g. Seismic Network configuration, magnitude of earthquakes of interest, heterogeneity, tectonic settings etc.) considered in determining the choice of radial distance in PSHA, common practices for different scales involving Local, Regional, and Global investigations could involve the following:
For Local Probabilistic seismic hazard analysis (PSHA) (e.g., site-specific hazard assessments), a typical radial distance might be 100 km or less. Regional PSHA may extend to 300 km or more, capturing broader tectonic features.
For Global-scale PSHA, the radial distance can be extensive, covering entire tectonic plates.
