What is Recurrence of Exceedence of Threshold Seismic Ground Motion from Earthquake Recurrence, Ground-Motion Attenuation, and Hypocentral-Depth Relations about?

In evaluating potential sites of major engineered facilities for purposes of preliminary screening, feasibility, or conceptual design it is important to establish the recurrence interval (return period) of critical levels of seismically-induced ground motion. An essential element in estimating this parameter both in regions with and without known seismogenic faults, is the analysis of "random" earthquakes. A useful tool in performing this analysis is the well known earthquake size-to-recurrence equation, \(\log _{10} \mathrm{~N}=\mathrm{a}-\) bM. This paper illustrates how this equation can be used with attenuation relations and hypocentral depths to estimate recurrence of exceedence of threshhold values of seismic ground-motion parameters. Intended for preliminary site screening, feasibility, and conceptual design studies in regions of "random" earthquakes, with or without seismogenic faults, the illustrated method of approach provides reasonable constraints to preliminary evaluation and site selection decisions when recurrence of threshhold ground motion is considered.
