This report summarizes the final assessments of geologic hazards at the Lawrence Livermore National Laboratory (LLNL). Detailed discussions of investigations are documented in a series of reports produced by LLNL's Site Seismic Safety Program and their consultants. The Program conducted a probabilistic assessment of hazards at the site as a result of liquefaction, landslide, and strong ground shaking, using existing models to explicitly treat uncertainties. The results indicate that the Greenville and Las Positas-Verona Fault systems present the greatest hazard to the LLNL site as a result of ground shaking, with a lesser contribution from the Calaveras Fault. Other, more distant fault systems do not materially contribute to the hazard. No evidence has been found that the LLNL site will undergo soil failures such as landslides or liquefaction. In addition, because of the locations and ages of the faults in the LLNL area, surface ground rupture during an earthquake is extremely unlikely.
