This report is one of a series of reports documenting the methods and findings of a multi-year, multi-disciplinary project conducted by the Pacific Earthquake Engineering Research Center (PEER) with the Lawrence Berkeley National Laboratory (LBNL) and funded by the California Energy Commission (CEC). The overall project is titled “Performance-based Earthquake Engineering Assessment Tool for Natural Gas Storage and Pipeline Systems” henceforth referred to as the “OpenSRA Project.”
The overall goal of the OpenSRA Project is to create an open-source, research-based seismic risk assessment tool for natural gas infrastructure that can be used by utility stakeholders to better understand state-wide risks, prioritize mitigation, plan new gas infrastructure, and help focus post-earthquake repair work.
The project team includes researchers from UC Berkeley, LBNL, UC San Diego, University of Nevada Reno, the NHERI SimCenter at UC Berkeley, and Slate Geotechnical Consultants and its subcontractors Lettis Consultants International (LCI) and Thomas O’Rourke. Focused research to advance the seismic risk assessment tool was conducted by Task Groups, each addressing a particular area of study and expertise, and collaborating with the other Task Groups.
This report is the product of Task Group B: Liquefaction-induced deformation and seismically induced slope displacement. The scope of this report is to summarize the procedures and data available in California for assessing liquefaction triggering, liquefaction-induced lateral spreading and vertical settlement, and seismic slope instability and displacement at statewide, regional, and site-specific scales. A new procedure for probabilistically assessing liquefaction triggering and lateral spread displacement at regional scales is introduced.
