This timely book provides the inside story of the development of mobile public alert and warning technology in the United States and addresses similar systems being used in Australia, Canada, Japan, and the Netherlands. This book provides a comprehensive account of how mobile-smartphone systems are transforming the practice of public alert and warning in the United States. Recent events have vaulted mobile alert and warning technology to the forefront of public debates concerning the hazards of the digital age. False alarms of ballistic missile attacks on Hawaii and Japan, the non-use of mobile alerts during the Northern California wildfires, and the role this technology plays in supporting police manhunts and counterterrorism efforts have prompted reconsideration of how these systems are used. Drawing upon interviews with officials, executives, experts, and citizens, the book provides an in-depth analysis of the events and contexts influencing the trajectory of mobile public alert and warning and charts a course for its improvement. The book first introduces readers to the high stakes involved in the transformation of public alert and warning, explaining how new research is revealing the benefits, limitations, and risks of mobile technology in the disaster communication context. Three case studies then illustrate issues of risk, trust, and appropriateness in mobile public alert and warning.

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.

The world is wrought with risks that may harm people and cost lives. The news is riddled with reports of natural disasters (wildfires, floods, earthquakes, hurricanes), industrial disasters (chemical spills, water and air pollution), and health pandemics (e.g., SARS, H1NI, COVID19). Effective risk communication is critical to mitigating harms. The body of research in this handbook reveals the challenges of communicating such messages, affirms the need for dialogue, embraces the role of instruction in proactively communicating risk, acknowledges the function of competing risk messages, investigates the growing influence of new media, and constantly reconsiders the ethical imperative for communicating recommendations for enhanced safety.

A much-needed look at the growth of emergency media and its impact on our lives In an emergency, we often look to media: to contact authorities, to get help, to monitor evolving situations, or to reach out to our loved ones. Sometimes we aren’t even aware of an emergency until we are notified by one of the countless alerts, alarms, notifications, sirens, text messages, or phone calls that permeate everyday life. Yet most people have only a partial understanding of how such systems make sense of and act upon an “emergency.” In Case of Emergency argues that emergency media are profoundly cultural artifacts that shape the very definition of “emergency” as an opposite of “normal.” Looking broadly across a range of contemporary emergency-related devices, practices, and services, Elizabeth Ellcessor illuminates the cultural and political underpinnings and socially differential effects of emergency media. By interweaving in-depth interviews with emergency-operation and app-development experts, archival materials, and discursive and technological readings of hardware and infrastructures, Ellcessor demonstrates that emergency media are powerful components of American life that are rarely, if ever, neutral. The normalization of ideologies produced and reinforced by emergency media result in unequal access to emergency services and discriminatory assumptions about who or what is a threat and who deserves care and protection. As emergency media undergo massive growth and transformation in response to digitization and attendant entrepreneurial cultures, Ellcessor asks where access, equity, and accountability fit in all of this. The first book to develop a typology of emergency media, In Case of Emergency opens a much-needed conversation around the larger cultural meanings of “emergency,” and what an ethical and care-based approach to emergency could entail.

The second edition of this vital text integrates theory, research, and application to orient readers to the latest thinking about the role of social media in crisis communication. Specific crisis arenas such as health, corporate, nonprofit, religious, political, and disaster are examined in depth, along with social media platforms and newer technology. Social Media and Crisis Communication, Second Edition provides a fresh look at the role of visual communication in social media and a more global review of social media and crisis communication literature. With an enhanced focus on the ethics section, a short communication overview piece, and case studies for each area of application, it is practical for use in a variety of learning settings. A must-read for scholars, advanced students, and practitioners who wish to stay on the leading edge of research, this book will appeal to those in public relations, strategic communications, corporate communications, government and NGO communications, and emergency and disaster response.
