Following a series of natural disasters, including Hurricane Katrina, that revealed shortcomings in the nation's ability to effectively alert populations at risk, Congress passed the Warning, Alert, and Response Network (WARN) Act in 2006. Today, new technologies such as smart phones and social media platforms offer new ways to communicate with the public, and the information ecosystem is much broader, including additional official channels, such as government social media accounts, opt-in short message service (SMS)-based alerting systems, and reverse 911 systems; less official channels, such as main stream media outlets and weather applications on connected devices; and unofficial channels, such as first person reports via social media. Traditional media have also taken advantage of these new tools, including their own mobile applications to extend their reach of beyond broadcast radio, television, and cable. Furthermore, private companies have begun to take advantage of the large amounts of data about users they possess to detect events and provide alerts and warnings and other hazard-related information to their users. More than 60 years of research on the public response to alerts and warnings has yielded many insights about how people respond to information that they are at risk and the circumstances under which they are most likely to take appropriate protective action. Some, but not all, of these results have been used to inform the design and operation of alert and warning systems, and new insights continue to emerge. Emergency Alert and Warning Systems reviews the results of past research, considers new possibilities for realizing more effective alert and warning systems, explores how a more effective national alert and warning system might be created and some of the gaps in our present knowledge, and sets forth a research agenda to advance the nation's alert and warning capabilities.
The Emergency Alert System (EAS) is built on a structure conceived in the 1950¿s when over-the-air broadcasting was the best-available technol. for widely disseminating emergency alerts. It is one of several federally managed warning systems. The NOAA/NWS weather radio system has been upgraded to an all-hazard warning capability. The Dept. of Homeland Security is implementing a program that will disseminate nat. alert messages over digital broadcast airwaves, using satellite and public TV broadcast towers. This program is called the Integrated Public Alert and Warning System (IPAWS).

Following an earlier NRC workshop on public response to alerts and warnings delivered to mobile devices, a related workshop was held on February 28 and 29, 2012 to look at the role of social media in disaster response. This was one of the first workshops convened to look systematically at the use of social media for alerts and warnings-an event that brought together social science researchers, technologists, emergency management professionals, and other experts on how the public and emergency managers use social media in disasters.In addition to exploring how officials monitor social media, as well as the resulting privacy considerations, the workshop focused on such topics as: what is known about how the public responds to alerts and warnings; the implications of what is known about such public responses for the use of social media to provide alerts and warnings to the public; and approaches to enhancing the situational awareness of emergency managers. Public Response to Alerts and Warnings Using Social Media: Report of a Workshop on Current Knowledge and Research Gaps summarizes presentations made by invited speakers, other remarks by workshop participants, and discussions during parallel breakout sessions. It also points to potential topics for future research, as well as possible areas for future research investment, and it describes some of the challenges facing disaster managers who are seeking to incorporate social media into regular practice.
This book presents a summary of the Workshop on Public Response to Alerts and Warnings on Mobile Devices: Current Knowledge and Research Gaps, held April 13 and 14, 2010, in Washington, D.C., under the auspices of the National Research Council's Committee on Public Response to Alerts and Warnings on Mobile Devices: Current Knowledge and Research Needs. The workshop was structured to gather inputs and insights from social science researchers, technologists, emergency management professionals, and other experts knowledgeable about how the public responds to alerts and warnings, focusing specifically on how the public responds to mobile alerting.
Initial priorities for U.S. participation in the International Decade for Natural Disaster Reduction, declared by the United Nations, are contained in this volume. It focuses on seven issues: hazard and risk assessment; awareness and education; mitigation; preparedness for emergency response; recovery and reconstruction; prediction and warning; learning from disasters; and U.S. participation internationally. The committee presents its philosophy of calls for broad public and private participation to reduce the toll of disasters.
A comprehensive system to alert the American people in times of hazard allows people to take action to save lives. FEMA is responsible for the current Emergency Alert System (EAS) and the development of the new Integrated Public Alert and Warning System (IPAWS). This report examined: (1) the current status of EAS; (2) the progress made by FEMA in implementing an integrated alert and warning system; and (3) the challenges involved in implementing an integrated alert and warning system. The report conducted a survey of states, reviewed FEMA and other documentation, and interviewed industry stakeholders and officials from federal agencies responsible for public alerting. Includes recommendations. Charts and tables.
The Emergency Alert System (EAS) is built on a structure conceived in the 1950's when over-the-air broadcasting was the best-available technology for widely disseminating emergency alerts. It is one of several federally managed warning systems. The Federal Emergency Management Agency (FEMA) jointly administers EAS with the Federal Communications Commission (FCC), in cooperation with the National Weather Service (NWS), an organization within the National Oceanic and Atmospheric Administration (NOAA). The NOAA/NWS weather radio system has been upgraded to an all-hazard warning capability. Measures to improve the NOAA network and the new Digital Emergency Alert System (DEAS) are ongoing. The Department of Homeland Security (DHS), working with the Association of Public Television Stations, is implementing a program that will disseminate national alert messages over digital broadcast airwaves, using satellite and public TV broadcast towers. This program, referred to as the Integrated Public Alert and Warning System (IPAWS), is part of the Department's response to an Executive Order requiring the Secretary of Homeland Security to meet specific requirements for an alert system as part of U.S. policy. Legislation was passed at the end of the 109th Congress (the Warning, Alert, and Response Network Act, or WARN Act, as signed into law as Title VI of P.L. 109347) to assure funding to public television stations to install digital equipment to handle national alerts. The law also required the establishment of a committee to provide the FCC with recommendations regarding the transmittal of emergency alerts by commercial mobile service providers to their subscribers. Committee recommendations provided the structure for a Commercial Mobile Alert System (CMAS). In addition to presidential alerts, which clearly are a federal responsibility, the service would transmit emergency alerts generated by state, local, and other nonfederal authorities. In the 110th Congress, S. 1223 (Senator Landrieu) and its companion bill, H.R. 2331 (Representative Melancon), would authorize funds to strengthen the radio broadcasting infrastructure that supports the Emergency Alert System. It would also provide for a pilot Broadcast Disaster Preparedness Grant Program. H.R. 2787 (Representative Ellsworth) would require the installation of weather radios in new manufactured (mobile) homes. H.R. 2787, known as CJ's Law, was passed by the House and is awaiting action in the Senate. Three bills would place statutory requirements on the development of IPAWS and would authorize funding to implement the program and conduct pilot tests. These are the Integrated Public Alert and Warning System Modernization Act of 2008 (H.R. 6038, Graves); the Alerting Lives Through Effective and Reliable Technological Systems (ALERTS) Act (H.R. 6392, Cuellar), which also addresses federal participation in operating parts of the CMAS alerting capability; and the Disaster Response, Recovery, and Mitigation Enhancement ACT (H.R. 6658, Oberstar). H.R. 6658 contains provisions covering a wide range of FEMA activities; in addition to reiterating the IPAWS provisions of H.R. 6038, the bill would create an advisory committee to make recommendations to FEMA concerning IPAWS and report to Congress on the committee's actions.
Since the dawn of medical science, people have recognized connections between a change in the weather and the appearance of epidemic disease. With today's technology, some hope that it will be possible to build models for predicting the emergence and spread of many infectious diseases based on climate and weather forecasts. However, separating the effects of climate from other effects presents a tremendous scientific challenge. Can we use climate and weather forecasts to predict infectious disease outbreaks? Can the field of public health advance from "surveillance and response" to "prediction and prevention?" And perhaps the most important question of all: Can we predict how global warming will affect the emergence and transmission of infectious disease agents around the world? Under the Weather evaluates our current understanding of the linkages among climate, ecosystems, and infectious disease; it then goes a step further and outlines the research needed to improve our understanding of these linkages. The book also examines the potential for using climate forecasts and ecological observations to help predict infectious disease outbreaks, identifies the necessary components for an epidemic early warning system, and reviews lessons learned from the use of climate forecasts in other realms of human activity.
