There's no doubt that Hurricane Katrina was one of the most devastating weather events to hit the United States-costing lives, property, and prosperity. In "Catastrophic Gumbo, " author Alvin JacQues provides a firsthand look at the facts, drama, details, and aftermath of this powerful storm. A survivor of Hurricane Katrina, JacQues considers himself lucky to be alive, and he credits his strong faith in God for both his survival and the opportunity to tell his story. In this memoir, he examines the enormous devastation and causalities and tells a heroic tale of survival. "Catastrophic Gumbo" includes more than thirty stories that describe what really happened during this natural disaster-including his rescue by the Coast Guard, his experience of six days of chaos at the Superdome, the drowning of his mother, the ever-present death and destruction that he witnessed, and the corruption of the New Orleans Police Department. A compelling account, "Catastrophic Gumbo" gives a behind-the-scenes and personal look at the before, during, and after of this tragedy that hit Louisiana, Mississippi, and Alabama in 2005.

From avalanches to volcanoes, and from the Gulf Oil Spill to bridge collapses, author Alvin JacQues explores the fascinating world of disasters-both manmade and natural. Inspired by his survival of Hurricane Katrina, chronicled in his first book "Catastrophic Gumbo, " JacQues delivers a compilation of facts and commentary on a number of global natural and manmade disasters, both historical and more recent, that have impacted the human race. Gathered from more than sixty locations, JacQues details the mayhem caused by a range of events that include an F5 tornado in Oklahoma, a typhoon in China, a blizzard in the United States, the flood of 1889, the sinking of the Titanic, and the crash of Flight 111. A compelling collection of stories, "Catastrophic Companions" narrates the reality of extreme events and communicates not only the power of Mother Nature, but of the perseverance of the human race to endure these tragedies for which often there is no preparation.

Past storms such as Hurricanes Andrew, Hugo, Charley, Katrina, and Rita, and recent events such as Hurricane Ike continue to show the vulnerability of our built environment. While good design and construction cannot totally eliminate risk, every storm has shown that sound design and construction can significantly reduce the risk to life and damage to property. With that in mind, the Federal Emergency Management Agency (FEMA) has developed this manual to help the community of homebuilders, contractors, and local engineering professionals in rebuilding homes destroyed by hurricanes, and designing and building safer and less vulnerable new homes. The intent of the manual is to provide homebuilders, contractors, and engineering professionals with a series of recommended foundation designs that will help create safer and stronger buildings in coastal areas. The designs are intended to help support rebuilding efforts after coastal areas have been damaged by floods, high winds, or other natural hazards. The foundations may differ somewhat from traditional construction techniques; however, they represent what are considered to be some of the better approaches to constructing strong and safe foundations in hazardous coastal areas. The objectives used to guide the development of this manual are: To provide residential foundation designs that will require minimal engineering oversight; To provide foundation designs that are flexible enough to accommodate many of the homes identified in A Pattern Book for Gulf Coast Neighborhoods prepared for the Mississippi Governor's Rebuilding Commission on Recovery, Rebuilding, and Renewal; To utilize model layouts so that many homes can be constructed without significant additional engineering efforts. The focus of this document is on the foundations of residential buildings. The assumption is that those who are designing and building new homes will be responsible for ensuring that the building itself is designed according to the latest building code (International Building Code(r), International Residential Code(r), and FEMA guidance) and any local requirements. The user of this manual is directed to other publications that also address disaster-resistant construction. Although the foundation designs are geared to the coastal environment subject to storm surge, waves, floating debris, and high winds, several are suitable for supporting homes on sites protected by levees and floodwalls or in riverine areas subjected to high-velocity flows. Design professionals can be contacted to ensure the foundation designs provided in this manual are suitable for specific sites. This edition of FEMA 550 introduces the Case H foundation, which is an open/deep foundation developed for use in coastal high hazard areas (V zones). It is also appropriate to use the Case H foundation in Coastal A and non-coastal A zones. Case H foundations incorporate elevated reinforced concrete beams that provide three important benefits. One, the elevated beams work in conjunction with the reinforced concrete columns and grade beams to produce a structural frame that is more efficient at resisting lateral loads than the grade beams and cantilevered columns used in other FEMA 550 open foundations. The increased efficiency allows foundations to be constructed with smaller columns that are less exposed to flood forces. The second benefit is that the elevated reinforced concrete beams provide a continuous foundation that can support many homes constructed to prescriptive designs from codes and standards such as the IRC, the American Forest and Paper Association's Wood Frame Construction Manual for One- and Two-Family Dwellings (WFCM), and the International Code Council's Standard for Residential Construction in High Wind Regions (ICC-600). The third benefit that Case H foundations provide is the ability to support relatively narrow homes. It is anticipated that Case H foundations can be used for several styles of modular ho

Nearly 1.7 million fires in the United States during 2002 claimed 3,380 lives, injured 18,425 people, and destroyed over $10 billion in property. Incendiary and suspicious acts (including arson), cooking and carelessness with open flames are the leading causes of fires. These causes have a common thread: human activity and human error. As such, most of these fires were likely preventable. Many activities that influence fire incidence change with the season of the year. In the winter, the need for heating increases. Hot, dry weather affects wildland areas and creates fire prone situations. Warm weather tends to bring people and their behaviors outdoors. Behaviors also change as people participate in various holiday customs and traditions. At some holidays, decorations in the home increase the load of combustible material. The use of candles and extra electric lighting may be used to celebrate other events. Fireworks are part of Fourth of July and other celebrations. As part of seasonal celebrations, people may prepare and cook elaborate meals. People also travel more, leaving some homes unoccupied while other homes increase in occupancy. Any of these behaviors can affect both the incidence and the severity of fires. By understanding the nature and scope of seasonal fires, public education and other fire related programs can be specifically targeted at these seasonal fire problems. This report first explores fire patterns by each season of the year; both the changes in incidence and the causes of fire are discussed. The report then focuses on the changes in fire profiles around four seasonal holidays: Independence Day, Halloween, Thanksgiving, and Christmas. These holidays were chosen because of their striking changes in fire patterns.

This guide was developed to fulfill several different objectives and address a wide audience with varying needs. The primary intent is to explain the sources of nonstructural earthquake damage in simple terms and to provide information on effective methods of reducing the potential risks. The recommendations contained in this guide are intended to reduce the potential hazards but cannot completely eliminate them. The primary focus of this guide is to help the reader understand which nonstructural items are most vulnerable in an earthquake and most likely to cause personal injury, costly property damage, or loss of function if they are damaged. In addition, this guide contains recommendations on how to implement cost effective measures that can help to reduce the potential hazards. This guide is intended primarily for use by a lay Audience building owners, facilities managers, maintenance personnel, store or office managers, corporate/agency department heads, business proprietors, homeowners, etc. Some readers may be small-business owners with a small number of potential problems that could be addressed in a few days' time by having at handyman install some of the generic details presented in this guide. Other readers may be responsible for hundreds of facilities and may need a survey methodology to help them understand the magnitude of their potential problems.

One of the goals of the Department of Homeland Security's Federal Emergency Management Agency (FEMA) and the National Earthquake Hazards Reduction Program (NEHRP) is to encourage design and building practices that address the earthquake hazard and minimize the resulting risk of damage and injury. Publication of this edition of the "NEHRP Recommended Provisions for Seismic Regulation of New Buildings and Other Structures" and its "Commentary" ("FEMA 450-2 / Part 2: Commentary") is a fitting end to the 25th year of the NEHRP and reaffirms FEMA's ongoing support to improve the seismic safety of construction in this country. Its publication marks the sixth edition in an ongoing series of updating of both the NEHRP Recommended Provisions and several complementary publications. FEMA was proud to sponsor the Building Seismic Safety Council for this project and we encourage the widespread dissemination and voluntary use of this state-of-the-art consensus resource document. This edition of the "NEHRP Recommended Provisions" contains several significant changes, including: a reformatting to improve its usability; introduction of a simplified design procedure, an updating of the seismic design maps and how they are presented; a modification in the redundancy factor; the addition of ultimate strength design provisions for foundations; the addition of several new structural systems, including buckling restrained braced frames and steel plate shear walls; structures with damping systems has been moved from an appendix to a new chapter; and inclusion of new or updated material industry reference standards for steel, concrete, masonry, and wood. The "NEHRP Recommended Provisions for Seismic Regulations for New Buildings and Other Structures" (referred to hereinafter as the "Provisions") present criteria for the design and construction of structures to resist earthquake ground motions. The purposes of these "Provisions" are as follows: 1. To provide minimum design criteria for structures appropriate to their primary function and use considering the need to protect the health, safety, and welfare of the general public by minimizing the earthquake-related risk to life and 2. To improve the capability of essential facilities and structures containing substantial quantities of hazardous materials to function during and after design earthquakes. The design earthquake ground motion levels specified herein could result in both structural and nonstructural damage. For most structures designed and constructed according to these "Provisions," structural damage from the design earthquake ground motion would be repairable although perhaps not economically so. For essential facilities, it is expected that the damage from the design earthquake ground motion would not be so severe as to preclude continued occupancy and function of the facility. The actual ability to accomplish these goals depends upon a number of factors including the structural framing type, configuration, materials, and as-built details of construction. For ground motions larger than the design levels, the intent of these "Provisions" is that there be a low likelihood of structural collapse. These "Provisions" shall apply to the design and construction of structures-including additions, changes of use, and alterations-to resist the effects of earthquake motions. Every structure, and portion thereof, shall be designed and constructed to resist the effects of earthquake motions as prescribed by these "Provisions."

Early on the morning of 4th September 2010, a series of seismic events began to unfold in Christchurch, New Zealand. They would eventually take 185 lives and directly affect hundreds of thousands of men, women and children. This book is a compilation of stories from some of these people. Preschoolers, teenagers, families, and retirees tell of the impact of the ongoing earthquakes and aftershocks, the emotional and physical toll they exacted, and their hope for a new Christchurch. They reflect the incredible resilience the people of Canterbury have shown throughout this devastating time. Some of the stories are poignant, some humorous, some shocking and some sad. All of them are from the heart and deserve to be heard. Magnitude 7.1 & 6.3 was put together by Debbie Roome who is an award-winning novelist and freelance writer with 25 years experience.

The Federal Emergency Management Agency (FEMA), which is part of the Department of Homeland Security, works to reduce the ever-increasing cost that disasters inflict on the nation. Preventing losses before they occur by designing and constructing buildings and their components to withstand anticipated forces from various hazards is one of the key components of mitigation and is one of the most effective ways of reducing the cost of future disasters. The National Earthquake Hazards Reduction Program (NEHRP) is the federal program established to address the nation's earthquake threat. NEHRP seeks to resolve two basic issues: how will earthquakes affect us and how do we best apply our resources to reduce their impact on our nation. The program was established by Congress under the Earthquake Hazards Reduction Act of 1977 (Public Law 95-124) and was the result of years of examination of the earthquake hazard and possible mitigation measures. Under the NEHRP, FEMA is responsible for supporting program implementation activities, including the development, publication, and dissemination of technical design and construction guidance documents. Generally, there has not been much technical guidance addressing residential buildings unless they are located in areas of high seismicity or exceed a certain size or height. This is because most residential buildings were thought to perform fairly well in earthquakes due to their low mass and simple construction. While buildings may not normally experience catastrophic collapse, they can still suffer significant amounts of damage, rendering them uninhabitable. This is especially true when construction techniques are less than adequate. What is particularly important from FEMA's point of view is that, given the sheer number of this type of building, even minor damage represents a significant loss potential and temporary housing demand that will need to be addressed after an earthquake by all levels of government. This guide provides information on current best practices for earthquake-resistant house design and construction for use by builders, designers, code enforcement personnel, and potential homeowners. It incorporates lessons learned from the 1989 Loma Prieta and 1994 Northridge earthquakes as well as knowledge gained from the FEMA-funded CUREE-Caltech Woodframe Project. It also introduces and explains the effects of earthquake loads on one- and two-family detached houses and identifies the requirements of the 2003 International Residential Code (IRC) intended to resist these loads. The stated purpose of the IRC is to provide: ..". minimum requirements to safeguard the public safety, health, and general welfare, through affordability, structural strength, means of egress facilities, stability, sanitation, light and ventilation, energy conservation and safety to life and property from fire and other hazards attributed to the built environment." Because the building code requirements are minimums, a house and its contents still may be damaged in an earthquake even if it was designed and built to comply with the code. Research has shown, however, that earthquake damage to a house can be reduced for a relatively small increase in construction cost. This guide identifies above-code techniques for improving earthquake performance and presents an estimate of their cost. Note that the information presented in this guide is not intended to replace the IRC or any applicable state or local building code, and the reader is urged to consult with the local building department before applying any of the guidance presented in this document. The information presented in this guide applies only to one- and two-family detached houses constructed using the nonengineered prescriptive construction provisions of the IRC. Applicable IRC limits on building configuration and construction are described.

Earthquakes represent an enormous threat to the Nation. Although damaging earthquakes occur infrequently, their consequences can be staggering. As recent earthquakes around the world have demonstrated, high population densities and development pressures, particularly in urban areas, are increasingly vulnerable. Unacceptably high loss of life and enormous economic consequences are associated with recent global earthquakes, and it is only a matter of time before the United States faces a similar experience. Earthquakes cannot be prevented, but their impacts can be managed to a large degree so that loss to life and property can be reduced. To this end, the National Earthquake Hazards Reduction Program (NEHRP) seeks to mitigate earthquake losses in the U.S. through both basic and directed research and implementation activities in the fields of earthquake science and engineering. This program is authorized and funded by Congress and is managed as a collaborative effort among the Federal Emergency Management Agency (FEMA), the National Institute of Standards and Technology (NIST), the National Science Foundation (NSF), and the United States Geological Survey (USGS). These four Federal organizations work in close coordination to improve the Nation's understanding of earthquake hazards and to mitigate their effects. The missions of the four agencies are complementary: FEMA, a component of the Department of Homeland Security, works with states, local governments, and the public to develop tools and improve policies and practices that reduce earthquake losses; NIST enables technology innovation in earthquake engineering by working with industry to remove technical barriers, evaluate advanced technologies, and develop the measurement and prediction tools underpinning performance standards for buildings and lifelines; NSF strives to advance fundamental knowledge in earthquake engineering, earth science processes, and societal preparedness and response to earthquakes; and USGS monitors earthquakes, assesses seismic hazard for the Nation, and researches the basic earth science processes controlling earthquake occurrence and effects. Mindful of the increasing threat posed by earthquakes, NEHRP initiated a review of the scientific goals and strategies of the Program and a discussion of the opportunities and priorities for the five-year interval 2001-2005. This review and discussion culminated in the new strategic plan presented here. Shaping the plan are four goals that represent the continuum of activities in the Program, ranging from research and development to application and implementation. These four goals are as follows: A. Develop effective practices and policies for earthquake loss-reduction and accelerate their implementation. B. Improve techniques to reduce seismic vulnerability of facilities and systems. C. Improve seismic hazard identification and risk assessment methods and their use. D. Improve the understanding of earthquakes and their effects.

This publication was equally funded by the National Oceanic and Atmospheric Administration (NOAA), which leads the National Tsunami Hazard Mitigation Program (NTHMP) and by the Federal Emergency Management Agency (FEMA), which is responsible for the implementation portion of the National Earthquake Hazard Reduction Program (NEHRP). This project was originally undertaken to address the need for guidance on how to build a structure that would be capable of resisting the extreme forces of both a tsunami and an earthquake. This question was driven by the fact that there are many communities along our nation's west coast that are vulnerable to a tsunami triggered by an earthquake on the Cascadia subduction zone, which could potentially generate a tsunami of 20 feet in elevation or more within 20 minutes. Given their location, it would be impossible to evacuate these communities in time, which could result in a significant loss of life. This issue came into sharp relief with the December 26, 2004 Sumatra earthquake and Indian Ocean tsunami. While this event resulted in a tremendous loss of life, this would have been even worse had not many people been able to take shelter in multi-story reinforced concrete buildings. Without realizing it, these survivors were among the first to demonstrate the concept of vertical evacuation from a tsunami. Many coastal communities subject to tsunami located in other parts of the country also have the same issue. In these cases, the only feasible alternative is vertical evacuation, using specially designed, constructed and designated structures built to resist both tsunami and earthquake loads. The design of such structures was the focus of the earlier work on this project, which resulted in the FEMA publication, Guidelines for Design of Structures for Vertical Evacuation from Tsunamis (FEMA P646). This is a companion publication intended to present information on how vertical evacuation design guidance can be used and encouraged at the state and local level. It is meant to help state and local government officials and interested citizens by providing them with the information they would need to address the tsunami hazard in their community, to help determine if vertical evacuation is an option they should consider, and if so, how to fund, design and build such a refuge.

This volume of selected readings and the handbook it accompanies have been developed to provide participants in the building process at the local, state, and regional levels with the information they need to adequately address the potential effects on their communities of using new or improved seismic safety design provisions in the development of regulations for new buildings. It represents one product of an ongoing program conducted by the Building Seismic Safety Council (BSSC) for the Federal Emergency Management Agency (FEMA). A brief description of this program is presented below so that readers of the handbook and these selected readings can approach their use with a fuller understanding of their purpose and limitations. In the chapters included in the handbook: The potential impacts identified by the committee are described. Information sources and data bases that may be able to provide communities with general as well as specific information and guidance are listed. General terms related to earthquakes are defined and the modified Mercalli intensity (MMI) scale and the Richter magnitude scale are described. In this accompanying volume of selected readings, the committee has assembled a series of papers that address various aspects of the seismic safety issue. A number of these papers were prepared specifically for the BSSC study and several were presented at the BSSC committee meetings with building process participants. Several other papers were originally presented at a 1984 FEMA workshop but were not published. Included are: An estimate of the impact of the NEHRP Recommended Provisions on design and construction costs developed for the BSSC study; Descriptions of the seismic hazard in various areas of the United States developed for the BSSC study; Explanations of seismic safety codes; Descriptions of current seismic hazard mitigation practices and programs; A description of recent seismic safety policy research developed for the BSSC study; A summary of the BSSC committee meetings with building process participants in Charleston, Memphis, St. Louis, and Seattle; A relatively extensive set of references.

Nonstructural failures have accounted for the majority of earthquake damage in several recent U.S. earthquakes. Thus, it is critical to raise awareness of potential nonstructural risks, the costly consequences of nonstructural failures, and the opportunities that exist to limit future losses. Nonstructural components of a building include all of those components that are not part of the structural system; that is, all of the architectural, mechanical, electrical, and plumbing systems, as well as furniture, fixtures, equipment, and contents. Windows, partitions, granite veneer, piping, ceilings, air conditioning ducts and equipment, elevators, computer and hospital equipment, file cabinets, and retail merchandise are all examples of nonstructural components that are vulnerable to earthquake damage. The primary purpose of this guide is to explain the sources of nonstructural earthquake damage and to describe methods for reducing the potential risks in simple terms. This guide is intended for use by a non-engineer audience located within the United States; this audience includes building owners, facility managers, maintenance personnel, store or office managers, corporate or agency department heads, business proprietors, risk managers, and safety personnel. The guide is also designed to be useful for design professionals, especially those who are not experienced with seismic protection of nonstructural components. It addresses nonstructural issues typically found in schools, office buildings, retail stores, hotels, data centers, hospitals, museums, and light manufacturing facilities. FEMA 74 explains the sources of earthquake damage that can occur in nonstructural components and provides information on effective methods for reducing risk associated with nonstructural earthquake damage. It is intended for use by a non-engineer audience that includes building owners, facility managers, maintenance personnel, store or office managers, corporate or agency department heads, and homeowners. The reference material contained within the third edition of FEMA 74 is now approaching 20 years old. A considerable amount of new information now exists as a result of ongoing National Earthquake Hazard Reduction Program (NEHRP) activities, local and state government programs, private sector initiatives, and academic work focused on reducing the potential for nonstructural earthquake damage.

Earthquakes damage structures - buildings, roads and bridges, utility and communications systems - and those damaged structures kill and injure people and cost a great deal to fix. And while the structures are not functioning, the businesses that rely on them either fail or face great financial hardship. Seismic safety advocates attempt to reduce all earthquake losses in various ways. Structures can be strengthened to resist shaking, either when they are built or later in their lives, or they can be sited in areas less subject to violent shaking. But increasing seismic safety requires knowledge of the earthquake hazard in a community or area, an understanding of how to reduce structural damages, and a willingness to spend the money and time necessary to do so. Decisions to invest in seismic safety are made by individuals, private and public sector organizations, and governments, so the goal of seismic safety is served by risk education, community activism, and political activism. Promoting seismic safety can be challenging because people seem indifferent to its benefits or decision-makers dismiss good ideas about ways to make buildings and communities more resistant to the damaging effects of earthquakes. Advocates work hard and care deeply, yet often feel that their efforts are ignored. Given these frustrations, advocates sometimes give up, or wait for another day. This resource kit is meant to inspire all advocates to keep working toward their goal. The briefs assembled here distill what we have learned-through research and experience over the last 40 years-about promoting seismic safety in the United States. Advocates can be almost anyone: people whose jobs involve public safety; design professional who want to make a difference; those who work in organizations with missions to increase seismic safety; and citizen-activists who have a personal stake in earthquake safety. Many potential advocates do not think of themselves as such because they are not trying to change seismic safety policy. But seismic safety can be increased at levels as various as design and building professional practices, planning commission and special district procedures, and implementation of public safety programs. Across the U.S., advocates have improved seismic safety in areas with moderate to very high degrees of seismic risk by arguing for reduction of future losses in damaging earthquakes, and by calling attention to the economic and social vulnerability of their community to the losses an earthquake could inflict. Especially important to consider are buildings that are built to out-of-date and inferior codes, where people nonetheless live and work. Successful advocates point out another rationale for seismic safety - more earthquake resilience in highways, power and utility systems, buildings, and communities means increased resilience to other types of damaging events, both natural and human-caused. Talking about seismic issues often has the benefit of raising questions about the condition of facilities or the readiness to respond to any extreme event.

Although earthquakes are an inevitable hazard, they are not inevitable disasters. Experiences in recent years have shown consistently that lifelines properly designed to resist earthquakes perform well in spite of severe earthquakes; those not so designed are subject to failure. Assessments of earthquake hazards indicate that one or more severe earthquakes can be expected to strike U.S. metropolitan areas in the next decade. Until actions are taken to improve the design and construction of lifelines, failures can be expected to result in substantial losses--estimated at billions of dollars and many lives for a single severe earthquake. The plan described in this document defines a process that, if activated, will begin the development of seismic design guidelines and standards for both new and existing lifelines. Lifelines are the public works and utility systems that support most human activities: individual, family, economic, political, and cultural. The various lifelines can be classified under the following five systems: electric power, gas and liquid fuels, telecommunications, transportation, and water supply and sewers. This plan for developing and adopting seismic design and construction guidelines and standards for lifelines has been prepared in response to Public Law 101-614, the National Earthquake Hazards Reduction Program (NEHRP) Reauthorization Act. The act requires the Federal Emergency Management Agency (FEMA), in consultation with the National Institute of Standards and Technology (NIST), to develop "a plan, including precise timetables and budget estimates, for developing and adopting, in consultation with appropriate private sector organizations, design and construction standards for lifelines" and "recommendations of ways Federal regulatory authority could be used to expedite the implementation of such standards." The Plan focuses on developing recommendations, encouraging and supporting the approval of these recommendations by the standards and professional organizations serving the lifeline community, and working with the lifeline community to achieve their effective implementation. Design guidelines lay out a set of principles, which for lifelines may include performance criteria, materials characteristics, and testing procedures for design, construction, maintenance, repair, and retrofitting of both existing and proposed systems. Guidelines provide a basis for making judgments or determining a course of action; they may evolve into recommendations for standards. A standard, according to the National Standards Policy Advisory Committee, is "a prescribed set of rules, conditions, or requirements concerning definitions of terms; classification of components; specification of materials, performance, or operation; delineation of procedures; or measurement of quantity and quality in describing materials, products, systems, services, or practices." Properly developed and effectively implemented lifeline seismic guidelines and standards will significantly reduce the vulnerability of both existing and proposed lifeline systems to future earthquakes. Guidelines and standards should (1) establish performance criteria for the construction, maintenance, and operation of existing and proposed lifeline systems, equipment, and materials for selected levels of seismic risk; (2) provide a basis for technical specifications for use by buyers and sellers of lifeline products and services to reduce the vulnerability of lifeline systems to earthquakes; and (3) provide a reliable basis for regulations to protect the public health, safety, and welfare.

This FEMA 154 Report, Rapid Visual Screening of Buildings for Potential Seismic Hazards: A Handbook, is the first of a two-volume publication on a recommended methodology for rapid visual screening of buildings for potential seismic hazards. The technical basis for the methodology, including the scoring system and its development, are contained in the companion FEMA 155 report, Rapid Visual Screening of Buildings for Potential Seismic Hazards: Supporting Documentation. The rapid visual screening procedure (RVS) has been developed for a broad audience, including building officials and inspectors, and government agency and private-sector building owners, to identify, inventory, and rank buildings that are potentially seismically hazardous. Although RVS is applicable to all buildings, its principal purpose is to identify (1) older buildings designed and constructed before the adoption of adequate seismic design and detailing requirements, (2) buildings on soft or poor soils, or (3) buildings having performance characteristics that negatively influence their seismic response. Once identified as potentially hazardous, such buildings should be further evaluated by a design professional experienced in seismic design to determine if, in fact, they are seismically hazardous. The RVS uses a methodology based on a "sidewalk survey" of a building and a Data Collection Form, which the person conducting the survey (hereafter referred to as the screener) completes, based on visual observation of the building from the exterior, and if possible, the interior. The Data Collection Form includes space for documenting building identification information, including its use and size, a photograph of the building, sketches, and documentation of pertinent data related to seismic performance, including the development of a numeric seismic hazard score. Once the decision to conduct rapid visual screening for a community or group of buildings has been made by the RVS authority, the screening effort can be expedited by pre-planning, including the training of screeners, and careful overall management of the process. Completion of the Data Collection Form in the field begins with identifying the primary structural lateral-load-resisting system and structural materials of the building. Basic Structural Hazard Scores for various building types are provided on the form, and the screener circles the appropriate one. For many buildings, viewed only from the exterior, this important decision requires the screener to be trained and experienced in building construction. The procedure presented in this Handbook is meant to be the preliminary screening phase of a multi-phase procedure for identifying potentially hazardous buildings. Buildings identified by this procedure must be analyzed in more detail by an experienced seismic design professional. Because rapid visual screening is designed to be performed from the street, with interior inspection not always possible, hazardous details will not always be visible, and seismically hazardous buildings may not be identified as such. Conversely, buildings initially identified as potentially hazardous by RVS may prove to be adequate.

Since earthquake shaking is possible almost everywhere in the United States, earthquake safety should be practiced by everyone. There is a great deal that you and your students can do to take care of yourselves during and after an earthquake. The lessons in this booklet cover planning, preparation, practice, and more practice. The classroom activities are designed for students in kindergarten through sixth grade. We provided teaching notes; "Learning Links" summarizing interdisciplinary connections; and a set of masters ready to reproduce for transparencies, handouts, and worksheets. Students find the topic of earthquakes fascinating. Their fascination may contain an element of fear, like the fear that arises in teaching fire safety. That fear can be reduced by reminding them that they are learning how to take care of themselves if an earthquake happens. Parents' fears may also need to be addressed. Let your students know that fear is a normal reaction to any danger. Make your message clear: We can't do anything to prevent earthquakes, but we can prepare ourselves to cope with them. We can help ourselves and others to do many things that will make our homes and schools safer. This publication provides ready-to-use, hands-on activities for students and teachers explaining what happens during an earthquake, how to prepare for earthquake shaking, and how to stay safe during and after an earthquake. The Federal Emergency Management Agency (FEMA) and the National Science Teachers Association have also prepared Earthquake: A Teacher's Package for K-6, which includes hands-on classroom activities to support all elementary subject areas: creative writing, art, mathematics, social studies, and science. Known as Tremor Troop, this publication contains matrices that link the classroom activities to the National Science Education Standards. For middle and high school teachers, FEMA and the American Geophysical Union have prepared Earthquake: A Teacher's Package for Grades 7-12. Classroom activities are described, and activity sheets for students and background material for teachers are provided in each of the volume's six units. Known as Seismic Sleuths, this publication also contains matrices that link the classroom activities to the National Science Education Standards.

The purpose of this manual is to assist interested states, coalitions of states, or confederations of local governments to develop and nurture seismic safety advisory boards. The first part contains "how-to" tips and advice to assist states that already have such panels in upgrading their advisory boards. The second part of the manual contains advice on strategic planning for improving seismic safety. Specifically, it includes guidelines for developing a model seismic risk management program by which to gauge progress. A seismic advisory board is a multi-disciplinary panel composed of volunteers with expertise in fields related to earthquakes and preparation for and response to earthquakes, such as earth sciences, engineering, emergency services, local government, social services, and public policy. They are drawn from the private sector, academia, and government. The board's functions are to: advise, the legislature and administrative agencies; advocate earthquake programs; promote improvements to seismic safety and procedures; identify seismic hazards; coordinate plans and actions of responsible agencies, programs, and government levels; gather, integrate, and transfer information from a wide range of sources; plan for the long-term implementation, review, and maintenance of seismic safety programs. The need for seismic safety advisory boards and for model seismic risk management programs is based on the following assumptions: A damaging earthquake can occur with little or no warning. With each passing year, the potential for one increases; Positive, goal-oriented leadership is a prerequisite to starting an effective advisory board; Organizations at many levels of government and in the private sector have responsibilities in seismic safety. The boar can help develop comprehensive and consistent programs for seismic safety and risk management; earthquakes can cause extensive property damage and endanger lives, but this risk can be reduced and managed by prudent policies for locating and designing structures; managing earthquake risks has collateral benefits, bringing about improved buildings, dams, transportation facilities, building stock, communications, fire safety, toxic materials management, and emergency response; concerted efforts bring long-term progress toward seismic safety. This manual is meant to help in the creation of a seismic safety advisory board - either as an autonomous agency or as part of an existing entity. It proved advice gained from dealing with existing hazards and offers options to consider when establishing a new board or revitalizing an existing board to meet the unique needs of a region.

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.

It is one of a series of companion publications addressing the issue of the seismic performance of steel moment-frame buildings. The set of companion publications includes: FEMA-350 - Recommended Seismic Design Criteria for New Steel Moment-Frame Buildings. This publication provides recommended criteria, supplemental to FEMA 302 - 1997 NEHRP Recommended Provisions for Seismic Regulations for New Buildings and other Structures, for the design and construction of steel moment-frame buildings and provides alternative performance-based design criteria. FEMA-351 - Recommended Seismic Evaluation and Upgrade Criteria for Existing Welded Steel Moment-Frame Buildings. This publication provides recommended methods to evaluate the probable performance of existing steel moment-frame buildings in future earthquakes and to retrofit these buildings for improved performance. FEMA-352 - Recommended Postearthquake Evaluation and Repair Criteria for Welded Steel Moment-Frame Buildings. This publication provides recommendations for performing postearthquake inspections to detect damage in steel moment-frame buildings following an earthquake, evaluating the damaged buildings to determine their safety in the postearthquake environment, and repairing damaged buildings. FEMA-353 - Recommended Specifications and Quality Assurance Guidelines for Steel Moment-Frame Construction for Seismic Applications. This publication provides recommended specifications for the fabrication and erection of steel moment frames for seismic applications. The recommended design criteria contained in the other companion documents are based on the material and workmanship standards contained in this document, which also includes discussion of the basis for the quality control and quality assurance criteria contained in the recommended specifications. The information contained in these recommended postearthquake damage assessment and repair criteria, hereinafter referred to as Recommended Criteria, is presented in the form of specific damage assessment, safety evaluation and repair procedures together with supporting commentary explaining part of the basis for these recommendations.

Recent decades have seen a dramatic earthquake related losses. In the past ten years estimated losses were twenty times larger than in the previous 30 years combined. FEMAs expenditures related to earthquake losses have become an increasing percentage of its disaster assistance budget. Predictions are that future single earthquakes, which will inevitably occur, may result in losses of $50-100 billion each. Losses are rising due to several factors. These include: a denser population of buildings being located in seismically active regions. an aging building stock and the increasing cost of business interruption. Nonstructural and contents damage are also large contributors to loss, especially in regions with high-technology manufacturing and health-care industries. It is this increase in losses from all hazards that has led FEMA to support actions to reduce future losses. One of these is Project Impact, an initiative to encourage loss reduction activities through partnerships at the local community level. One of the key components of Project Impact is the community's adoption and enforcement of an adequate building code. Performance Based Seismic Design (PBSD) is a methodology that provides a means to more reliably predict seismic risk in all buildings in terms more useful to building users. PBSD will benefit nearly all building users. The PBSD methodology will be used by code writers to develop building codes that more accurately and consistently reflect the minimum standards desired by the community. A performance based design option in the code will facilitate design of buildings to higher standards and will allow rapid implementation of innovative technology. When performance levels are tied to probable losses in a reliability framework, the building design process can be tied into owner's long-term capital planning strategies, as well as numerical life cycle cost models. PBSD is not limited to the design of new buildings. With it, existing facilities can be evaluated and/or retrofitted to reliable performance objectives. Sharing the common framework of PBSD, existing buildings and new buildings can be compared equitably. It is expected that a rating system will develop to replace the currently used Probable Maximum Loss (PML) system. Such a system is highly desirable to owners, tenants, insurers, lenders, and others involved with building financial transactions. Despite its inconsistency and lack of transparency, the PML system is widely used and a poor rating often creates the financial incentive needed for retrofit decisions. This Action Plan presents a rational and cost effective approach by which building stakeholders: owners, financial institutions, engineers, architects, contractors, researchers, the public and governing agencies, will be able to move to a performance based design and evaluation system. The Plan recognizes that there is a strong demand from stakeholder groups for more reliable, quantifiable and practical means to control building damage. It also recognizes that there is not a focused understanding among these groups as to how these goals can be obtained. This Plan describes how performance based seismic design guidelines can be developed and used to achieve these goals. It will be a vehicle to bring together the diverse sets of demands from within the stakeholder groups and distill them into cohesive and practical guidelines. It engages each of the groups in the development these guidelines, by which future building design will become more efficient and reliable.

The Interagency Committee on Dam Safety (ICODS) was established to provide the Federal agencies involved in dam safety with the opportunity to coordinate their dam safety activities. One of the goals of ICODS is to provide a common forum for the Federal agencies and State officials to exchange ideas and procedures that are used for dam safety and to provide an efficient mechanism for technology transfer. The purpose of this document is to establish a common Glossary of Terms for Dam Safety.

Damage to earthen dams and dam safety issues associated with tree and woody vegetation penetrations of earthen dams is all too often believed to be a routine maintenance situation by many dam owners, dam safety regulators, and engineers. Contrary to this belief, tree and woody vegetation penetrations of earthen dams and their appurtenances have been demonstrated to be causes of serious structural deterioration and distress that can result in failure of earthen dams. For the first time in the history of dam safety, a Research Needs Workshop on Plant and Animal Impacts on Earthen Dams (Workshop) was convened through the joint efforts of the Federal Emergency Management Agency (FEMA) and the Association of State Dam Safety Officials (ASDSO) in November 1999 to bring together technical resources of dam owners, engineers, state and federal regulators, wildlife managers, foresters, and members of academia with expertise in these areas. The Workshop highlighted the realization that damage to earthen dams resulting from plant and animal penetrations was indeed a significant dam safety issue in the United States. The purpose of this Technical Manual for Dam Owners, Impacts of Plants on Earthen Dams is to convey technology assembled through the Workshop by successful completion of four objectives. These objectives are as follows: 1. Advance awareness of the characteristics and seriousness of dam safety problems associated with tree and woody vegetation growth impacts on earthen dams; 2. Provide a higher level of understanding of dam safety issues associated with tree and woody vegetation growth impacts on earthen dams by reviewing current damage control policies; 3. Provide state-of-practice guidance for remediation design considerations associated with damages associated with tree and woody vegetation growth on earthen dams; and 4. Provide rationale and state-of-practice techniques and procedures for management of desirable and undesirable vegetation on earthen dams.
