are contained in the referenced SRP section of the corresponding primary branch. The geologic and seismic information which must be provided in order for the site review to proceed is divided into the following three categories: 1. Geologic features: mass-wasting, differential subsidence, faulting, chemical weathering, cavernous or karst terrains, evidence of pre- consolidation, for example, by means of overburden removal through erosional processes. 2. Seismic features: ground failure under dynamic loading, liquefaction, vibratory ground motion, tsunami, and residual stresses. 3. Man-made conditions: changes in groundwater conditions, subsidence or collapse caused by withdrawal of fluids or mineral extraction, induced seismicity and fault movement caused by fluid injection (including reser- voir impoundment) or withdrawal. Information relating to the above conditions as presented in SAR Sections 2.5.1.1 (Regional Geology) and 2.5.1.2 (Site Geology), should be reviewed in terms of the regional and site physiography, geomorphology, stratigraphy, lithology, and tectonics. In addition, with specific reference to site geology, the follow- ing subjects should be reviewed as they relate to the above-mentioned conditions: topography, slope stability, fluid injection or withdrawal, mineral extraction, faulting, shearing, jointing, seismicity and fracturing. The above information should be documented by appropriate references to all relevant published and unpublished materials. Illustration should include but should not be limited to physiographic, topographic, geologic, tectonic, gravity, and magnetic maps, structure and stratigraphic sections, boring logs, and aerial photographs. Certain sites will require illustrations of specialized character such as maps of subsidence, irregular weathering conditions, landslide potential, hydrocarbon extraction (oil or gas wells), faults, joints, and karst features. Some site characteristics must be documented by reference to seismic
