"The Central and Eastern United States Seismic Source Characterization for Nuclear Facilities (CEUS-SSC) Project was conducted from April 2008 to December 2011 to provide the nuclear industry a new, regional seismic source model for use in conducting probabilistic seismic hazard analyses (PSHAs) for nuclear facilities. PSHA is used as a method for accounting for uncertainty in seismic design and in calculating seismic risk. Unlike previous seismic hazard studies, the CEUS-SSC Project was sponsored through an industry-government partnership. The study was conducted using the Senior Seismic Hazard Analysis Committee (SSHAC) Study Level 3 assessment process. The SSHAC process ensures consideration of the knowledge and uncertainties of the larger technical community within a robust and transparent framework."

The data includes geological information and other aspects relevant to other studies such as the Appalachian Basin Project.
