註釋

Using standard methods of probabilistic seismic risk analysis, estimates of the seismic hazards for six Minuteman missile wings were evaluated. The wings are located at Malstrom, Ellsworth, Minot, Whiteman, F.E. Warren and Grad Forks Air Force Bases. For each site, estimates of the site intensity, acceleration, velocity and displacement annual risk curves were made based on the historical seismicity within 1000 km of each site. Based on these curves, composite design response spectra for 10-, 100-, and 1000-year return period motions were calculated. Plots of the reported earthquake epicenters near each site were also generated. To conduct these studies, a new method for regional modification of peak acceleration attenuation functions was developed and is presented in the appendix to this report. Modifications to this scheme are presently being made and are expected to result in some change in the risk estimates for Whiteman AFB. (Author).
