The objectives were: (1) to develop a seismic hazard characterization methodology for the region east of the Rocky Mountains (EUS), and (2) the application of the methodology to 69 site locations, some of them with several local soil conditions. The method developed uses expert opinions to obtain the input to the analyses. An important aspect of the elicitation of the expert opinion process was the two feedback meetings with all "experts" in order to finalize the methodology and the input data bases. The hazard estimates are reported in terms of peak ground acceleration (PGA) and 5% damping velocity response spectra (PSV). A total of eight volumes make up this report which contains a thorough description of the methodology, the expert opinion's elicitation process, the input data base as well as a discussion, comparison and a summary volume. [Note: The digital version linked here is Volume 1 providing methodology, input data and comparisons to previous results for ten test sites. Remaining volumes are in paper copy] Consistent with previous analyses, the study finds that there are uncertainties associated with the estimates of seismic hazard in the EUS, and it assigns motion modeling as the prime contributor to those uncertainties. The data bases and software are made available to the NRC and to the public uses through the National Energy Software Center (Argonne, Illinois). See also the 2012 updated reports.
