and if all capable tectonic sources that could, based on their orientations, extend to within 8 km (5 mi) of the site are evaluated with respect to their potential for causing surface deformation. In conjunction with these discussions, a plot of the earthquake epicenters superimposed on a map showing the local capable tectonic sources should have been provided. Subsection 2.5.3.4 Ages of Most Recent Deformations. In meeting the requirements of References 1 and 2, this subsection is acceptable when every significant fault, or fold associated with a blind fault, any part of which is within 8 km (5 mi) of the site, is investigated in sufficient detail using geological and geophysical techniques of sufficient sensitivity to demonstrate, or allow relatively accurate estimates of, the age of most recent movement and identify geological evidence for previous displacements if it exists (Ref. 3). An evaluation of the sensitivity and resolution of the exploratory techniques used should be given. Subsection 2.5.3.5 Relationship of Tectonic Structures in the Site Area to Regional Tectonic Structures. In meeting the requirements of References 1 and 2, this subsection is satisfied by a discussion of the structural and genetic relationship between site area faulting or other tectonic deformation and the regional tectonic framework. In regions of active tectonism it may be necessary to conduct detailed geological and geophysical investigations to assess possible structural relationships of site area faults to regional faults known to be seismically active. Subsection 2.5.3.6 Characterization of Capable Tectonic Sources. In meeting the requirements of References 1 and 2, this subsection is acceptable when it 2.5.3-4 Rev. 3 - March 1997 has been demonstrated that the investigative techniques used have sufficient sensitivity to identify all potential capable tectonic sources such as faults, V Xor folds associated with blind faults, within 8 km (5 mi) of the site; and "'__ when the
