Revision 5 – July 2014 (4) Correlation of Earthquakes with Tectonic Features. The reviewer assesses how the applicant has investigated correlation of earthquakes with potential tectonic sources in conjunction with consideration of SRP Section 2.5.2. Historical earthquake data derived from review of SRP Section 2.5.2 are compared with known tectonic features in the site vicinity and a determination is made regarding whether any earthquakes can reasonably be associated with these tectonic structures. This determination includes an evaluation of the hypocentral error estimates of the earthquakes. When available, earthquake source mechanisms should be evaluated with respect to fault type (reverse, normal, strike-slip) and characteristics such as orientation and slip history. The applicant shall evaluate the relationship of fault parameters to earthquake magnitude. This type of assessment will likely provide insights on the potential for future surface displacements. In addition, small earthquakes correlated to growth fault movements or fluid injection or withdrawal should be considered in appropriate areas to discern between tectonic activity and man induced events or to determine potential future movements on growth fault systems. (5) Relationship of Geological Features in the Site Vicinity to Regional Geological Features. The reviewer evaluates relationships of tectonic structures in the site vicinity with regional tectonic structures by using a literature review to determine that the applicant's evaluation of the regional tectonic framework is reasonable. The reviewer confirms that conclusions reached by the applicant are based on acceptable geologic principles and have considered appropriate geologic and geophysical data. The reviewer considers the resolution accuracy of the investigation methods used by the applicant. (6) Potential for Surface Deformation at the Site. The reviewer evaluates the information provided by the applicant to characterize past surface
