Progress to Date - continued GIR Findings (partial) Geology, Seismicity and Potential Hazards Seismicity Faulting: indicated that the peninsula-section of the San Andreas fault passes ~2. 5 miles SW of the site and has the potential to generate a maximum earthquake of Mw = 7. 1 The site is not located within a earthquake Fault Hazard Zone Jan 25, 2005 CF Overview Status David Saenz saenzd@slac. stanford. edu

Progress to Date - continued Ground Shaking Reports indicates that a number of past earthquakes have affected the area, 1906 and the Loma Prieta earthquake of Oct 17, 1989 During the Loma Prieta earthquake, movements of <0. 4” vertically and ~0. 2” horizontally occurred in the LINAC concrete housing near its junction with the SLC tunnel Future earthquakes as estimated by USGS estimated the chance of one or more major (>M 6. 7) along the San Andreas fault have a 21% chance of occurrence between 2003 and 2032 The probability of major faults in the SF Bay area during the same time period is estimated to be 62% Jan 25, 2005 CF Overview Status David Saenz saenzd@slac. stanford. edu

Progress to Date - continued Geology, Seismicity and Potential Hazards Summary Potential Hazards for faulting is considered low! Potential Hazard due to ground shaking is considered to be high! Potential Hazard of flooding is low! Potential Hazard of Slope Instability, in the form of slumps, is considered moderate to high during a major earthquake or rainy season at east/west sides of the berm and at the slope/bowl at the CEH Jan 25, 2005 CF Overview Status David Saenz saenzd@slac. stanford. edu

Progress to Date - continued Recommendations for Surface Structures (partial) BTH Since the structural loads from the thick concrete walls are required, the structural loads on the foundations are expected to be high. Therefore, a drilled pier foundation system is recommended using minimum 24” dia piers with a spacing of 6 times the pier diameter Interface with Existing Buried Structures Potential for some heave of the PEP tunnel during the construction phase of the X-Ray Transport tunnel Tunnels and Caverns Tunnel sections with larger cross sections should not be advanced full-face but sub-divided with a segmental approach Jan 25, 2005 CF Overview Status David Saenz saenzd@slac. stanford. edu
