Abstract

The inclusion of epistemic uncertainties, generally via logic trees (Kulkarni et al., 1984), within probabilistic seismic‐hazard assessments (PSHAs) is becoming standard for all types of studies (commercial, governmental, or research; site specific, national, regional, or global). Consequently many studies publish expected ground motions for a given annual frequency of exceedance (AFE) or return period derived from the hazard curves for the mean, median, and various fractiles (percentiles).
