This research evaluates the seismic vulnerability of the Critical Energy Infrastructure (CEI) Hub and the associated fuel repercussions for the expected 9.0 magnitude earthquake along the Cascadia Subduction Zone. The tanks in the CEI hub are analyzed based on size and content. The owners and secondary containment areas are discussed using the same parameters. Various analysis techniques are reviewed to determine the most appropriate seismic fragility estimate for the site. The seismic vulnerability is analyzed using fragility curves by Hazus, American Lifeline Alliance, and D’Amico. The fragility curves are applied to the CEI Hub to determine expected damage and the related fuel loss impacts. Gasoline and diesel have the highest expected damage with a maximum prediction of 13.7 million and 9.5 million gallons respectively experiencing complete content loss.
