ABSTRACT

Lifeline Infrastructure and Collocation Exposure to the HayWired Earthquake Scenario -- A Summary of Hazards and Potential Service Disruptions   [open pdf - 41MB]

From the Abstract: "This chapter provides a comprehensive exposure analysis of five interacting lifeline infrastructure systems (comprised of facilities and conveyances) to six different HayWired earthquake scenario hazards. The lifeline infrastructure systems examined are transportation, water supply and wastewater, oil and gas, electric power, and telecommunications. The hazards considered are the HayWired mainshock ground shaking, surface rupture (represented as coseismic slip and afterslip), liquefaction, landslides, fire following the earthquake, and aftershocks. New geographic information system methods were developed to: (1) create a more detailed liquefaction probability map for the San Francisco Bay region that is not limited to a census-tract scale; (2) map relative levels of earthquake hazard intensities into a single multi-hazard intensity map; and (3) map collocation and density of infrastructure systems in a multihazard environment. Using these new methods, we look at the interaction between lifeline infrastructure systems and hazards in several ways: the exposure of single lifeline infrastructure types to single hazards; the exposure of single lifeline infrastructure systems to combinations of multiple hazards; and potential interactions between systems in hazardous areas after an earthquake."
