The first book on the Bhopal disaster, written on site a few weeks after the accident. "The people knew right away the source of the poisonous air, although it was incredible and shocking. Thousands had fled their homes a few months before upon the occasion of a small discharge of gas and an associated rumor of disaster. Now they choked and screamed at one another to rise and flee, aiding each other when they could, the choking and gagging leading the fully blinded. Some stepped out of their huts at the first whiffs, strangling, and were too blinded to turn back in, were swept in the gathering human torrent and often never saw their families, neighbors and friends again..." "A moving account of a shattering experience." - Arun Gandhi "Rightly, Al de Grazia highlights the important role of a Free Press. The Press has had to battle secrecy and suppression to expose the full extent of the Bhopal tragedy. Conitnuing now to assail the shocking failures of managers and officials in India and the USA, we must demand the reform of the irresponsible liaison between governments and multinational corporations." - S. B. Kolpe
The original Earthquakes -A Teacher's Package for K-6 (FEMA 159) was developed as a joint effort of the Federal Emergency Management Agency (FEMA) and the National Science Teachers Association (NSTA) under contract with FEMA. NSTA's project team produced an excellent product. Since its publication in 1988, over 50,000 teachers have requested copies. This revised version brought members of the original project team together with a group of teachers who had used the materials extensively in their classroom and served as teacher-educators at FEMA's Tremor Troop workshops. About 75% of the original material remains unchanged: a few activities were removed and a few added. A major change was the addition of assessments throughout the units. The examples we provide relate to life outside the classroom and/or activities similar to those of scientists. We also added matrices linking activities to the National Science Education Standards. The Teacher's Package has five units. Each of the first four units is divided into three levels: Level 1, for grades K-2; Level 2, for grades 3-4; and Level 3, for grades 5-6. Since classes and individuals vary widely you may often find the procedures in the other levels helpful for your students. The last unit has four parts with activities for students in all grades, K-6. Unit L, Defining an Earthquake, builds on what students already know about earthquakes to establish a working definition of the phenomenon. Legends from near and far encourage children to create their own fanciful explanations, paving the way for the scientific explanations they will begin to learn in this unit. Unit I, Why and Where Earthquakes Occur, presents the modern scientific understanding of the Earth's structure and composition, and relates this to the cause of earthquakes. Unit II, Physical Results of Earthquakes, provides greater understanding of the processes that shape our active Earth. Earthquakes are put in the context of the large- and small-scale changes that are constantly at work on the continents as well as the ocean floor. Unit IV, Measuring Earthquakes, explains earthquakes in terms of wave movement and introduces students to the far-ranging effects of earthquakes. Unit V, Earthquake Safety and Survival, focuses on what to expect during an earthquake; how to cope safely; how to identify earthquake hazards; and how to reduce, eliminate, or avoid them.
Recent earthquakes around the world show a pattern of steadily increasing damages and losses that are due primarily to two factors: (1) significant growth in earthquake-prone urban areas and (2) vulnerability of the older building stock, including buildings constructed within the past 20 years. In the United States, earthquake risk has grown substantially with development while the earthquake hazard has remained relatively constant. Understanding the hazard requires studying earthquake characteristics and locales in which they occur while understanding the risk requires an assessment of the potential damage to the built environment and to the welfare of people - especially in high risk areas. Estimating the varying degree of earthquake risk throughout the United States is useful for informed decision-making on mitigation policies, priorities, strategies, and funding levels in the public and private sectors. For example, potential losses to new buildings may be reduced by applying seismic design codes and using specialized construction techniques. However, decisions to spend money on either of those solutions require evidence of risk. In the absence of a nationally accepted criterion and methodology for comparing seismic risk across regions, a consensus on optimal mitigation approaches has been difficult to reach. While there is a good understanding of high risk areas such as Los Angeles, there is also growing recognition that other regions such as New York City and Boston have a low earthquake hazard but are still at high risk of significant damage and loss. This high risk level reflects the dense concentrations of buildings and infrastructure in these areas constructed without the benefit of modern seismic design provisions. In addition, mitigation policies and practices may not have been adopted because the earthquake risk was not clearly demonstrated and the value of using mitigation measures in reducing that risk may not have been understood. This study highlights the impacts of both high risk and high exposure on losses caused by earthquakes. It is based on loss estimates generated by HAZUS(r)-MH, a geographic information system (GIS)-based earthquake loss estimation tool developed by the Federal Emergency Management Agency (FEMA) in cooperation with the National Institute of Building Sciences (NIBS). The HAZUS tool provides a method for quantifying future earthquake losses. It is national in scope, uniform in application, and comprehensive in its coverage of the built environmen
One of the activities authorized by the Dam Safety and Security Act of 2002 is research to enhance the Nation's ability to assure that adequate dam safety programs and practices are in place throughout the United States. The Act of 2002 states that the Director of the Federal Emergency Management Agency (FEMA), in cooperation with the National Dam Safety Review Board (Review Board), shall carry out a program of technical and archival research to develop and support: improved techniques, historical experience, and equipment for rapid and effective dam construction, rehabilitation, and inspection; devices for continued monitoring of the safety of dams; development and maintenance of information resources systems needed to support managing the safety of dams; and initiatives to guide the formulation of effective policy and advance improvements in dam safety engineering, security, and management. With the funding authorized by the Congress, the goal of the Review Board and the Dam Safety Research Work Group (Work Group) is to encourage research in those areas expected to make significant contributions to improving the safety and security of dams throughout the United States. The Work Group (formerly the Research Subcommittee of the Interagency Committee on Dam Safety) met initially in February 1998. To identify and prioritize research needs, the Subcommittee sponsored a workshop on Research Needs in Dam Safety in Washington D.C. in April 1999. Representatives of state and federal agencies, academia, and private industry attended the workshop. Seventeen broad area topics related to the research needs of the dam safety community were identified. To more fully develop the research needs identified, the Research Subcommittee subsequently sponsored a series of nine workshops. Each workshop addressed a broad research topic (listed below) identified in the initial workshop. Experts attending the workshops included international representatives as well as representatives of state, federal, and private organizations within the United States. Impacts of Plants and Animals on Earthen Dams; Risk Assessment for Dams; Spillway Gates; Seepage through Embankment Dams; Embankment Dam Failure Analysis; Hydrologic Issues for Dams; Dam Spillways; Seismic Issues for Dams; Dam Outlet Works. Based on the research workshops, research topics have been proposed and pursued. Several topics have progressed to products of use to the dam safety community, such as technical manuals and guidelines. For future research, it is the goal of the Work Group to expand dam safety research to other institutions and professionals performing research in this field. The proceedings from the research workshops present a comprehensive and detailed discussion and analysis of the research topics addressed by the experts participating in the workshops. The participants at all of the research workshops are to be commended for their diligent and highly professional efforts on behalf of the National Dam Safety Program. The National Dam Safety Program research needs workshop on Hydrologic Issues for Dams was held on November 14-15, 2001, in Davis, California. The Department of Homeland Security, Federal Emergency Management Agency, would like to acknowledge the contributions of the U.S. Army Corps of Engineers, Hydrologic Engineering Center, which was responsible for the development of the technical program, coordination of the workshop, and development of these workshop proceedings. A complete list of workshop facilitators, presenters, and participants is included in the proceedings.
The US Dam Safety community has similar needs and activities to those of the European (EU) Dam Safety community. There has been an emphasis in the EU community on investigation of extreme flood processes and the uncertainties related to these processes. The purpose of this project was to cooperate with the organizations involved in these investigations over a three year period. The purpose of this cooperation was to: 1) coordinate US and EU efforts and collect information necessary to integrate data and knowledge with US activities and interests related to embankment overtopping and failure analysis, 2) Utilize the data obtained by both groups to improve embankment failure analysis methods, and 3) provide dissemination of these activities and their results to the US dam safety community. Dissemination was to be accomplished by: 1) Conducting a special workshop at a professional society meeting involving invited speakers from Europe and the United States. This session was held as a one day workshop at the Annual Conference of the Association of State Dam Safety Officials 2004 Dam Safety. The title of the day long workshop was; "Workshop on International Progress in Dam Breach Evaluation." Ten presentations were included in the workshop (see appendix for manuscripts). 2) A final report integrating EU and US research findings and results related to earthen embankment overtopping failure over the 3-year period would be developing and reporting in the form of a FEMA/USDA document. This report is included in the following pages.
Communities face many challenges following a disaster, including determining where the limited resources for their recovery are to be expended. After the initial "emergency" phase of a disaster response is completed, such as the rescue of those in need, the repair of critical services including water and power, and the restoration of key governmental functions, a community becomes focused on its long-term rebuilding. It is important to understand that there may be multiple funding sources available after a disaster event, but that resources may not be sufficient to undertake all the projects a community may ultimately need for full recovery. A first step for many communities may be to look to existing local comprehensive plans, capital improvement plans, hazard mitigation plans, or other similar documents to identify previously developed project priorities. The process identified in this Recovery Value Tool builds upon those priorities and provides a systematic methodology to evaluate recovery projects for the community. Fundamentally, this tool allows for an evaluation of priorities based upon the impacts of the recent disaster and the physical and community needs that have been caused by the event. Therefore, this process can provide a comprehensive evaluation of the needs, identify the most effective projects for the resources available, and allow for a more holistic combination of resources to accomplish the community's goals. This version of the Long-Term Community Recovery (LTCR) Recovery Value Tool presents a standardized methodology for determining the recovery value of post-disaster reconstruction projects. Prioritizing need, identifying projects to meet the need and determining which projects have the highest recovery value are critical steps to guide a community's long-term recovery from a disaster. The Tool incorporates best practices developed on a number of successful pilot recovery planning initiatives throughout the country. The Tool has been released with expedited review and is intended to meet the immediate needs of the communities impacted by the 2005 hurricane season. It is expected that revisions will be made to this tool as a result of refinement of the Long-Term Community Recovery planning process. The objective of the Recovery Value Tool is to assist in determining a project's value to the long-term recovery of a community from a particular disaster. The Recovery Value Tool will: Define what a Recovery Value is and how it fits into the planning process; Provide an objective assessment of each project's recovery value; Assist in determining implementation priorities; Provide documentation to funding agencies regarding a project's anticipated long-term impact.

The Department of Homeland Security, Federal Emergency Management Agency, would like to acknowledge the contributions of the U.S. Army Corps of Engineers, Hydrologic Engineering Center, which was responsible for the development of the technical program, coordination of the workshop, and development of these workshop proceedings.
In recent years, tremendous strides have been made by Federal, State, Tribal, and local governments to educate the public about natural disasters. Localities are now better able to respond to disasters, recover from their impact, and mitigate future damage. However, it remains a fact that in situations of catastrophic proportions, nothing that technology or preparedness has provided can prevent the inherent discontinuity in our lives caused by major disasters. Such events must be responded to through a cooperative Federal, State, Tribal, and local effort. When a disaster occurs, it is the responsibility first of the local community and then the State to respond. Often, their combined efforts are not sufficient to cope effectively with the direct results of the disaster. This situation calls for Federal assistance to supplement State, Tribal, and local efforts. The Robert T. Stafford Disaster Relief and Emergency Assistance Act, 42 U.S.C. Section 5121 - 5207, authorizes the President to provide such assistance. Assistance is coordinated through the Federal Emergency Management Agency (FEMA), a component of the Department of Homeland Security. This guide explains how FEMA implements that portion of the law that authorizes Federal grants for infrastructure recovery through its Public Assistance (PA) Program. Potential recipients of this funding include State, Tribal, and local governments and certain types of Private Nonprofit (PNP) organizations. A fundamental goal of the PA Program is to ensure that everyone shares a common understanding of the program policies and procedures. To support this goal, FEMA has undertaken an effort to provide the State, Tribal, and local partners with more and better information about the PA Program. This guide describes the PA Program's basic provisions and application procedures. The guide may be of interest to elected leaders, emergency managers, city engineers, public works directors, financial management personnel, managers of eligible PNP organizations, and other individuals who have the responsibility for restoring a community's infrastructure in the wake of a disaster.
This document is a comprehensive guide to the National Incident Management System Supporting Technology Evaluation Program (NIMS STEP). Evaluation activities are sponsored by the National Preparedness Directorate (NPD), Federal Emergency Management Agency (FEMA). This guide is designed to provide an orientation to the evaluation process and policies including vendor application requirements, product selection methods, evaluation activities, and post-evaluation review/reporting processes. Homeland Security Presidential Directive (HSPD)-5 directed the Secretary of Homeland Security to develop and administer the National Incident Management System (NIMS). In 2004, the Department of Homeland Security (DHS) released NIMS to provide a consistent nationwide template to enable governments and responders to work together effectively and efficiently to manage incidents and planned events. Although the incident management framework can be adaptable to any situation, NIMS provides a standard structure and management concepts that transcend all incidents, including: Accountability, Common Terminology, Comprehensive Resource Management, Information and Intelligence Management, Integrated Communications, Management Span-of-Control, Modular Organization, Unified Command Structure. The NIMS provides a framework and sets forth, among others, the requirement for interoperability and compatibility to enable a diverse set of public and private organizations to conduct well-integrated and effective incident management operations. Systems operating in an incident management environment must be able to work together and not interfere with one another. Interoperability and compatibility are achieved through the use of tools such as common communications and data standards. Establishing and maintaining a common operating picture and ensuring accessibility and interoperability are the principal goals of the Communication and Information Management component of NIMS. The NIMS STEP supports NIMS implementation by providing an objective evaluation of supporting technologies - the use and incorporation of new and existing technologies to improve efficiency and effectiveness in all aspects of incident management. The Incident Management Systems Integration (IMSI) Division of NPD has tasked the NIMS Support Center (NIMS SC) to support and manage the day-to-day functions of the program.
Hurricane Charley made landfall on Friday, August 13, 2004, at Mangrove Point, just southwest of Punta Gorda, Florida. On August 19, 2004, the Federal Emergency Management Agency's (FEMA's) Mitigation Division deployed a Mitigation Assessment Team (MAT) to Florida to assess damages caused by Hurricane Charley. This report presents the MAT's observations, conclusions, and recommendations in response to those field investigations. Several maps included in our first chapter illustrate the path of the storm, the wind field estimates, the impact on people and infrastructure, and the depth of storm surge along the path. The width of the high-wind field was very narrow even though hurricane force winds affected some portion of the Florida peninsula from Punta Gorda to Daytona Beach. There was little storm surge or coastal flooding because of the narrow size of the storm and the translational speed with which it came ashore and crossed the state. The hurricane is believed to have been a design wind event (the wind speeds equaled or exceeded those delineated in the current version of the Florida Building Code FBC]) for a narrow area from the point of landfall on the west coast inland for 120 miles. The design wind speed for Charlotte County (Punta Gorda) per the FBC is 114 to 130 mph (measured as a 3-second peak gust). The actual measured wind speed near Punta Gorda was 112 mph (3-second peak gust) and measured speeds in other parts of the state suggest that Charley was a design wind event. The storm created a very small area affected by storm surge and most damage was not caused by flooding from storm surge, waves, or erosion. Because Hurricane Charley was a design level wind event, the resultant storm damage provides valuable evidence about the effectiveness of building codes and design practices as they ad-dress design guidelines for high winds. For buildings built prior to the adoption of the current codes, judgments were made about how the observed damage was reflective of the code to which the building was constructed, and the quality of construction or the inspection process that followed construction. Consideration also was given to the type and use of buildings. Many buildings that were expected to function for critical/essential services were severely damaged by the hurricane and lost function for significant periods of time after the event. The recommendations in this report are based solely on the observations and conclusions of the MAT, and are intended to assist the State of Florida, local communities, businesses, and individ-uals in the reconstruction process and to help reduce damage and impact from future natural events similar to Hurricane Charley. The general recommendations presented in Section 8.1 relate to policies and education/outreach that are needed to ensure that designers, contractors, and building officials understand the requirements for disaster resistance construction in hurricane-prone regions.
On August 24, 1992, Hurricane Andrew struck southern Dade County, Florida, generating high winds and rain over a vast area of the county. Although the storm produced high winds and high storm surge, the effects of the storm surge and wave action were limited to a relatively small area of the coastal floodplain. It was evident from the extensive damage caused by wind, however, that wind speeds are significant. In September 1992, the Federal Emergency Management Agency's (FEMA's) Federal Insurance Administration (FIA), at the request of the FEMA Disaster Field Office Staff, assembled a Building Performance Assessment Team. The task of the team was to survey the performance of residential buildings in the storm's path and to provide findings and recommendations to both the Interagency Hazard Mitigation Team and the Dade County Building Code Task Force. The basis for performing the survey is that better performance of building systems can be expected when causes of observed failures are corrected using recognized standards of design and construction. The assessment team developed recommendations for reducing future hurricane damage such as that resulting from Hurricane Andrew. Recommendations included areas of concern such as building materials, construction techniques, code compliance, quality of construction, plan review, inspection, and reconstruction/retrofit efforts. The recommendations presented in this report may also have application in other communities in Florida. This report presents the team's observations of the successes and failures of buildings in withstanding the effects of Hurricane Andrew, comments on building failure modes, and provides recommendations for improvements intended to enhance the performance of buildings in future hurricanes.
Earthquakes are a serious threat to safety in hotel and motel buildings and pose a significant potential liability to owners and operators. Hotel and motel buildings in 39 states are vulnerable to earthquake damage. Unsafe existing buildings expose hotel and motel building owners, operators, and guests to the following risks: Death and injury to guests, visitors, and staff; Damage to or collapse of buildings; Damage to and loss of furnishings, equipment, and other building contents; and Disruption of hospitality functions and building operations. The greatest earthquake risk is associated with existing hotel and motel buildings that were designed and constructed before the use of modern building codes. For many parts of the United States, this includes buildings built as recently as the early 1990s. Although vulnerable hotel and motel buildings should be replaced with safe, new construction or rehabilitated to correct deficiencies, for many building owners, new construction is limited, at times severely, by budgetary constraints, and seismic rehabilitation is expensive and disruptive. However, incremental seismic rehabilitation, an innovative approach that phases in a series of discrete rehabilitation actions over a period of several years, is an effective, affordable, and non-disruptive strategy for responsible mitigation action that can be integrated efficiently into ongoing facility maintenance and capital improvement operations to minimize cost and disruption. This manual and its companion documents are the products of a Federal Emergency Management Agency (FEMA) project to develop the concept of incremental seismic rehabilitation-that is, building modifications that reduce seismic risk by improving seismic performance and that are implemented over an extended period, often in conjunction with other repair, maintenance, or capital improvement activities. It provides operators of hotels and motels and their owners, be they Real Estate Investment Trusts (REITs), pension funds, partnerships, individuals, or other forms of ownership, with the information necessary to assess the seismic vulnerability of their buildings and to implement a program of incremental seismic rehabilitation for those buildings.
Britain and the world were shocked in October 1966 by live television pictures coming from a small mining village in Wales. They showed a human tragedy unfolding after thousands of tons of coal waste fell from a mountainside onto its primary school and surrounding houses. The majority of the 144 people killed were children under 12. After more than 50 years the survivors of that disaster -- among the worst in Britain's peacetime history -- still live with painful memories and all-too-real after effects. In this first ever oral history of the tragedy, people who were there tell their stories, some speaking publicly for the first time. Built around 27 extensive interviews, Surviving Aberfan is a story of official neglect and betrayal, horror and great sadness. But it also demonstrates how courage, hope and effort can rebuild a devastated community and move forward.
Horrified, saddened, and angered: That was the American people's reaction to the 9/11 attacks, Hurricane Katrina, the Virginia Tech shootings, and the 2008 financial crisis. In Consuming Catastrophe, Timothy Recuber presents a unique and provocative look at how these four very different disasters took a similar path through public consciousness. He explores the myriad ways we engage with and negotiate our feelings about disasters and tragedies-from omnipresent media broadcasts to relief fund efforts and promises to "Never Forget." Recuber explains how a specific and "real" kind of emotional connection to the victims becomes a crucial element in the creation, use, and consumption of mass mediation of disasters. He links this to the concept of "empathetic hedonism," or the desire to understand or feel the suffering of others. The ineffability of disasters makes them a spectacular and emotional force in contemporary American culture. Consuming Catastrophe provides a lively analysis of the themes and meanings of tragedy and the emotions it engenders in the representation, mediation and consumption of disasters.
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.
The financing of hazard mitigation continues to, be one of the more difficult impediments to creating a seismically safe environment for Californians. Both State and local governments have undertaken mitigation utilizing a variety of funding mechanisms. California is one of the most seismically active States in the U.S. The statistics generated by seismologists are sobering. Over the coming decades variously sized earthquakes can be expected throughout the State, some with catastrophic damage potential. A sample statistic: there is a 90% probability that either the San Francisco Bay Area or the Los Angeles basin will suffer a magnitude 7 or larger earthquake by the year 2020. Each of the many large earthquakes predicted throughout the State can cause billions of dollars in property damage, loss of human life, injury, and disruptions in transportation, communications and utilities. As one response to this threat, because unreinforced masonry buildings (URMs) are susceptible to serious damage in a major earthquake, in 1986 the State of California adopted what is commonly referred to as "the URM Law." As discussed later in this Handbook, this law requires municipalities and counties within the most seismically active zones in the State to identify and create hazard mitigation programs for the unreinforced masonry buildings in their jurisdiction. A number of earthquake experts are now recommending that such identification and mitigation be applied to other seismically hazardous structures as well, including concrete frame structures lacking ductile connections, poorly designed tilt-up concrete buildings with inadequate roof-wall connections, and older (pre-1960) homes with inadequate strength in their foundations or cripple walls. The URM Law stopped short of requiring the owners of URM buildings to upgrade their structures. Many communities, however, have taken the initiative and mandated retrofitting of privately-owned URMs and other hazardous buildings. A few jurisdictions have mitigated the URM hazard in their community and more are in the process of doing so. The vast majority of jurisdictions, however, having identified some or all of the hazards, are wondering what they might do to mitigate them. This Handbook has been designed with that group in mind. The Handbook was conceived as part of an effort to find sources of financing for retrofit of privately owned hazardous buildings. The first step in the research process was to survey the 520 cities, towns and counties in California as to the status of their URM retrofit programs, and to gather information on any financial and non-financial incentive programs they may have established. Although more than 35% of those surveyed did respond, very few respondents had implemented any retrofit incentive programs. While the survey did not reveal the pot of gold, we were excited and encouraged by the creativity and resourcefulness of the few jurisdictions which have found ways to leverage or develop financing while promoting retrofitting in their communities. Their efforts are described in this Handbook. The heart of the Handbooklies in the CASE STUDIES, which describe steps to promote retrofitting taken by jurisdictions throughout California that may serve as models for others. The case studies were selected from responses to our survey. We met with staff at these municipalities to develop the case studies, which include descriptions of these jurisdictions' programs, as well as discussions of their programs' development, the resources they require, and their effectiveness.
This book provides background information and educational materials to help state officials promote the adoption and enforcement of state and local model building codes that contain the latest seismic provisions. These codes can reduce the damage that will inevitably occur when future earthquakes strike at-risk parts of the country. This book is intended for state officials, especially for earthquake program managers and hazard mitigation officers in the emergency management agencies of the states and territories prone to earthquakes. It is designed to help you convince your state and local governments that codes are effective, inexpensive, and a good investment for the future of our communities. Chapters 2 and 3 of this book contain background material on the purpose, function, and effectiveness of building codes in general and seismic codes in particular. Chapters 3,4, and 5 describe step-by-step processes for adopting state or local codes and for administering codes. Several appendices contain: the history and principles of seismic design, current seismic design practices in the United States, examples of state building code requirements, examples of state legislation, examples of local code Administration, the services of the three model code organizations in the United States, sources of further information and addresses, recommended readings, educational material for making local presentations, sample press releases for the media, sample brochures aimed at local audiences, a glossary of relevant terms.
A considerable number of buildings in the existing building stock of the United States present a risk of poor performance in earthquakes because there was no seismic design code available or required when they were constructed, because the seismic design code used was immature and had flaws, or because original construction quality or environmental deterioration has compromised the original design. The practice of improving the seismic performance of existing buildings-known variously as seismic rehabilitation, seismic retrofitting, or seismic strengthening-began in the U.S. in California in the 1940s following the Garrison Act in 1939. This Act required seismic evaluations for pre-1933 school buildings. Substandard buildings were required to be retrofit or abandoned by 1975. Many school buildings were improved by strengthening, particularly in the late 1960s and early 1970s as the deadline approached. Local efforts to mitigate the risks from unreinforced masonry buildings (URMs) also began in this time period. In 1984, the Federal Emergency Management Agency (FEMA) began its program to encourage the reduction of seismic hazards posed by existing older buildings throughout the country. Recognizing that building rehabilitation design is far more constrained than new building design and that special techniques are needed to insert new lateral elements, tie them to the existing structure, and generally develop complete seismic load paths, a document was published for this purpose in 1992. FEMA 172, NEHRP Handbook of Techniques for the Seismic Rehabilitation of Existing Buildings (FEMA, 1992b), was intended to identify and describe generally accepted rehabilitation techniques. The art and science of seismic rehabilitation has grown tremendously since that time with federal, state, and local government programs to upgrade public buildings, with local ordinances that mandate rehabilitation of certain building types, and with a growing concern among private owners about the seismic performance of their buildings. In addition, following the demand for better understanding of performance of older buildings and the need for more efficient and less disruptive methods to upgrade, laboratory research on the subject has exploded worldwide, particularly since the nonlinear methods proposed for FEMA 273 became developed. The large volume of rehabilitation work and research now completed has resulted in considerable refinement of early techniques and development of many new techniques, some confined to the research lab and some widely used in industry. Like FEMA 172, this document describes the techniques currently judged to be most commonly used or potentially to be most useful. Furthermore, it has been formatted to take advantage of the ongoing use of typical building types in FEMA documents concerning existing buildings, and to facilitate the addition of techniques in the future. The primary purpose of this document is to provide a selected compilation of seismic rehabilitation techniques that are practical and effective. The descriptions of techniques include detailing and constructability tips that might not be otherwise available to engineering offices or individual structural engineers who have limited experience in seismic rehabilitation of existing buildings. A secondary purpose is to provide guidance on which techniques are commonly used to mitigate specific seismic deficiencies in various model building types. The goals of the document are to: Describe rehabilitation techniques commonly used for various model building types, Incorporate relevant research results, Discuss associated details and construction issues, Provide suggestions to engineers on the use of new products and techniques.
In 2003, the U.S. Fire Administration (USFA) announced a goal to reduce firefighter fatalities by 25 percent within 5 years and 50 percent within 10 years. It also committed to doing research that would support that goal. The consistently high annual percentage of fatalities related to fire department response and roadway scene operations prompted the USFA to look at several aspects related to these collisions in an effort to improve responder safety. Firefighters who are killed in privately owned vehicles (POVs) during the course of their duties account for the largest percentage of vehicle-related deaths. These are typically volunteer firefighters who are responding to or returning from emergency calls. However, career firefighters are also occasionally killed in POVs while performing their duties. The original edition of this "Traffic Incident Management Systems" (TIMS) report was released in 2008 as part of a cooperative agreement between the UFSA and the International Fire Service Training Association (IFSTA) at Oklahoma State University (OSU). The project was funded by the DOT Federal Highway Administration (FHWA). This latest edition of TIMS was developed in response to the release of the 2009 edition of the DOT/FHWA's Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD). It becomes evident that injuries and deaths that occur at roadway emergency scenes are a major concern to emergency responders. The purpose of this report is to focus on the causes of firefighter injuries and deaths when working on roadway incidents. This report will focus on the causes of these incidents and provide strategies for mitigating them in the future. The occurrence and severity of these incidents can be reduced through proper roadway incident scene tactics and incident management, information which will be covered in the remaining chapters of this document.
The Nation has made measurable strides toward improving preparedness for the full range of hazards at all levels of government and across all segments of society. National preparedness has improved not only for the countless threats posed by those who wish to bring harm to the American homeland but also for the many natural and technological hazards that face the Nation's communities. Presidential Policy Directive 8: National Preparedness (PPD-8) describes the Nation's approach to preparing for the threats and hazards that pose the greatest risk to the security of the United States. The Directive requires a National Preparedness Report (NPR), an annual report summarizing the progress made toward building, sustaining, and delivering the 31 core capabilities described in the National Preparedness Goal (the Goal). As the NPR coordinator, the U.S. Department of Homeland Security's (DHS's) Federal Emergency Management Agency (FEMA) worked with the full range of whole community partners-including all levels of government, private and nonprofit sectors, faith-based organizations, communities, and individuals-to develop the NPR. Specifically, FEMA collaborated with federal interagency partners to identify quantitative and qualitative performance and assessment data for each of the 31 core capabilities. In addition, FEMA integrated data from the 2011 State Preparedness Reports (SPRs), statewide self-assessments of core capability levels submitted by all 56 U.S. states and territories through a standardized survey. Finally, FEMA conducted research to identify recent, independent evaluations, surveys, and other supporting data related to core capabilities. FEMA synthesized, reviewed, and analyzed all of these data sources in order to derive key findings that offer insight on critical issues in preparedness, including areas where the Nation has made progress and where areas of improvement remain. During the development of specific core capability key findings, eight broader trends in national preparedness emerged. As shown below, these overarching key findings synthesize information from across multiple core capabilities and mission areas and reflect national-level results on preparedness progress and gaps. With the September 2011 release of the Goal, the Nation is transitioning to a new set of core capabilities. As a result, whole community partners are updating their efforts to collect, analyze, and report preparedness progress according to the Goal's core capabilities and preliminary targets. The 2012 NPR therefore relies on a range of existing assessment approaches and associated quantitative and qualitative data to present the Nation's preparedness progress and to report key findings. Assessment processes, methodologies, and data will evolve in future years to align more directly with the Goal and its capabilities. Efforts are already underway to refine the Goal's capabilities and preliminary targets; future efforts will focus on developing agreed-upon measures and assessment methodologies that will guide the annual development of the NPR.
One of the primary goals of the Department of Homeland Security's Federal Emergency Management Agency (FEMA) is prevention or mitigation of this country's losses from hazards that affect the built environment. To achieve this goal, we as a nation must determine what level of performance is expected from our buildings during a severe event, such as an earthquake, blast, or hurricane. To do this, FEMA contracted with the Applied Technology Council (ATC) to develop next-generation performance-based seismic design procedures and guidelines, which would allow engineers and designers to better work with stakeholders in identifying the probable seismic performance of new and existing buildings. These procedures could be voluntarily used to: (1) assess and improve the performance of buildings designed to a building code "life safety" level, which would, in all likelihood, still suffer significant structural and nonstructural damage in a severe event; and (2) more effectively meet the performance targets of current building codes by providing verifiable alternatives to current prescriptive code requirements for new buildings. Advancement of present-generation performance-based seismic design procedures is widely recognized in the earthquake engineering community as an essential next step in the nation's drive to develop resilient, loss-resistant communities. This Program Plan offers a step-by-step, task-oriented program that will develop next-generation performance-based seismic design procedures and guidelines for structural and nonstructural components in new and existing buildings. This FEMA 445 Program Plan is a refinement and extension of two earlier FEMA plans: FEMA 283 Performance-Based Seismic Design of Buildings - an Action Plan, which was prepared by the Earthquake Engineering Research Center, University of California at Berkeley in 1996, and FEMA 349 Action Plan for Performance Based Seismic Design, which was prepared by the Earthquake Engineering Research Institute in 2000. The state of practice for performance-based assessment, performance-based design of new buildings, and performance-based upgrades of existing buildings will all be significantly advanced under this Program Plan. The preparation of this Program Plan, and developmental work completed to date, has been performed by the Applied Technology Council (ATC) under the ATC-58 project entitled Development of Next-Generation Performance-Based Seismic Design Guidelines for New and Existing Buildings. The technological framework developed under this program is transferable and can be adapted for use in performance-based design for other extreme hazards including fire, wind, flood, and terrorist attack. The decision-making tools and guidelines developed under this Program Plan will greatly improve our ability to develop cost-effective and efficient earthquake loss reduction programs nationwide. |
