onsibilities addressed in SRP Section 2.5.2. Close coordination between geologists, geophysicists, seismologists, and geotechnical specialists is essential for a thorough review. The reviewer confirms that sufficient information is provided to estimate the potential for strong earthquake ground motions and surface tectonic deformation at the site and to enable assessment of the Ground Motion Response Spectrum (GMRS) proposed for the site. This information includes proximity and character of potential seismic sources, geologic evidence for Quaternary deformation (faulting or folding), evidence of prehistoric earthquakes (i.e., paleoliquefaction features), and other seismically-induced features. Adequate information on characteristics of subsurface materials beneath the site, including basic data addressing soil and rock stability (e.g., rock quality designations) and liquefaction potential, must be provided or cross-referenced with SRP Section 2.5.4. These data must be reviewed by the staff so potential for amplification of vibratory ground motion or ground failure under dynamic loading conditions can be assessed. Potential ground failure modes include liquefaction, collapse of unstable slopes, excessive settlement, differential settlement, and failure induced by high tectonic stresses. In addition, for sites adjacent to large bodies of water, information pertinent to assessing hazards from probable maximum tsunami and seiche must be provided or cross-referenced to SRP Section 2.4.12. 2. Non-Tectonic Deformation Information The reviewer confirms that the application provides adequate information for assessment of potential for non-tectonic deformation, including landslides and other mass-wasting phenomena; subsidence, to include differential subsidence; slip along 2.5.1-3 Revision 4 - March 2007 growth faults; glacially-induced deformation; and potential for collapse or subsidence in areas underlain by carbonate rocks.
