Abstract: The economic effects of lifelines failures, caused by three hypothesized earthquake scenarios, in the city of Everett, Washington are estimated. The project team consists of lifeline seismic vulnerability modeling specialists, earthquake hazard development specialists, the lifeline operators in the city of Everett and two of the major businesses in Everett. The lifeline systems that are modeled are the water, sewer, telephone, natural gas, power and transportation systems. Both repair and replacement costs of damaged lifeline facilities, and loss of business opportunity costs to the lifeline operators and lifeline customers are estimated. The estimates consider individual lifeline system outages and the combined effect of lifeline system outages. In addition to developing Everett specific loss estimates, the study demonstrates how earthquake related losses due to lifeline failures can be estimated for other cities.
