Abstract: The USGS National Seismic Hazard Model (NSHM) is a flagship product that provides probabilistic estimates of seismic hazard for the United States. Traditionally, the NSHM provides the basis for seismic design and risk assessment of buildings; in turn, these engineering applications provide important feedback for periodic updates of the NSHM. Unlike the context of buildings, a similar feedback loop currently does not exist for the context of critical infrastructure systems such as gas pipelines. To explore how the NSHM can be leveraged for gas pipeline risk, we develop a first-order assessment of earthquake risk to gas pipelines in the conterminous United States, identify key knowledge gaps, and present options for closing these gaps.

Bio: N. Simon Kwong received his BEng degree in Civil Engineering from The Cooper Union in New York City and both MS and PhD degrees in Structural Engineering from the University of California Berkeley. Before joining the Earthquake Hazards Program at GHSC as a Mendenhall researcher, Simon worked on various problems related to selecting input earthquake ground motions for nonlinear dynamic finite-element analyses of structures. Currently, his research focuses on understanding seismic risks and uncertainties related to U.S. gas pipelines, with the goal of delivering knowledge for mitigating risks to critical infrastructure systems in the United States.
