Book excerpt: Lifeline is an earthquake engineering term denoting those systems necessary for human life and urban function, without which large urban regions cannot exist. Lifelines basically convey food, water, fuel, energy, information, and other materials necessary for human existence from the production areas to the consuming urban areas. Prolonged disruption of lifelines such as the water supply or electric power for a city or urbanized region would inevitably lead to major economic losses, deteriorated public health, and eventually population migration. Earthquakes are probably the most likely natural disaster that would lead to major lifeline disruption. With the advent of more and more advanced technology, the United States has increasingly become dependent on the reliable provision of lifeline related commodities, such as electric power, fuel, and water. A natural question is: What is the potential for major disruption to these lifelines, especially at the regional level? The initiation of this study by the Federal Emergency Management Agency (FEMA) is based in part on a need to better understand the impact of disruption of lifelines, from earthquakes and to assist in the identification and prioritization of hazard mitigation measures and policies. In addition, the report is intended to improve national awareness of the importance of protecting lifeline systems from earthquakes, and of assuring lifeline reliability and continued serviceability. The specific contractual requirements of this project and report are: To assess the extent and distribution of existing U.S. lifelines, and their associated seismic risk; and To identify the most critical lifelines, and develop a prioritized series of steps for reduction of lifeline seismic vulnerability, based on overall benefit. FEMA is also sponsoring a companion study to develop and demonstrate a model methodology for assessing the seismic vulnerability and impact of disruption of water transmission and distribution systems. In this initial study, lifelines of critical importance at the U.S. national level have been analyzed to estimate overall seismic vulnerability and to identify those lifelines having the greatest economic impact, given large, credible U. S. earthquakes. The lifelines examined include electric systems; water, gas, and oil pipelines; highways and bridges; airports; railroads; ports; and emergency service facilities. The vulnerability estimates and impacts developed are presented in terms of estimated direct damage losses and indirect economic losses. These losses are considered to represent a first approximation because of the assumptions and methodology utilized, because several lifelines are not included, and because, in some cases, the available lifeline inventory data lack critical capacity information.

This book was released on 2013-03-15 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lifelines (e.g., systems and facilities that deliver energy fuel and systems and facilities that provide key services such as water and sewage, transportation, and communications are defined as lifelines) are presently being sited in "utility or transportation corridors" to reduce their right-of-way environmental, aesthetic, and cost impacts on the communities that rely upon them. The individual lifelines are usually designed, constructed, and modified throughout their service life. This results in different standards and siting criteria being applied to segments of the same lifeline, and also to different standards or siting criteria being applied to the separate lifelines systems within a single corridor. Presently, the siting review usually does not consider the impact of proximity or collocation of the lifelines on their individual risk or vulnerability to natural or manmade hazards or disasters. This is either because the other lifelines have not yet been installed or because such a consideration has not been identified as being an important factor for such an evaluation. There have been cases when some lifeline collocations have increased the levels of damage experienced during an accident or an earthquake. For example, water line ruptures during earthquakes have led to washouts which have caused foundation damage to nearby facilities. In southern California a railroad accident (transportation lifeline) led to the subsequent failure of a collocated fuel pipeline, and the resulting fire caused considerable property damage and loss of life. Loss of electric power has restricted, and sometimes failed, the ability to provide water and sewer services or emergency fire fighting capabilities. In response to these types of situations, the Federal Emergency Management Agency (FEMA) is examining the use of such corridors, and FEMA initiated this study to examine the impact of siting multiple lifeline systems in confined and at-risk areas. The overall FEMA project goals are to develop managerial tools that can be used to increase the understanding of the lifeline systems' vulnerabilities and to help identify potential mitigation approaches that could be used to reduce those vulnerabilities. Another program goal is to identify methods to enhance the transfer of the resulting information to lifeline system providers, designers, builders, managers, operators, users, and regulators. This report presents the analytic methods developed to define the collocation impacts and the resulting analyses of the seismic and geologic environmental loads on the collocated lifelines in the Cajon Pass. The assumed earthquake event is similar to the 8.3 magnitude, San Andreas fault, Ft. Tejon earthquake of 1857. In this, report a new analysis method is developed and applied to identify the increase in the vulnerability of the individual lifeline systems due to their proximity to other lifelines in the Cajon Pass. A third reports presents an executive summary of the study. The Cajon Pass Lifeline Inventory report and this present report taken together provide a specific example of how the new analysis method can be applied to a real lifeline corridor situation.

Available in PDF, EPUB and Kindle. Book excerpt: Prepared by the Council on Disaster Reduction and the Technical Council on Lifeline Earthquake Engineering of ASCE. This TCLEE Monograph provides engineers and decision makers with tools to help them better understand acceptable risk processes and then develop risk reduction strategies and implement mitigation actions to reduce lifeline losses from future earthquakes. The disruption of lifelines from natural hazards has a direct impact on the world's regional economies and the health of their citizens. Therefore, it is important to understand what natural hazards are, how they can affect infrastructure lifelines, and what can be done to minimize their impact. These three elements, in turn, influence decisions that involve acceptable risk processes. The topic of "acceptable risk" provides one way of bringing integrated systems risk evaluations for disaster explicitly into a decision-making context. Topics include technical issues; risk criteria issues; and communication, administration, and regulation issues.
