Under the National Construction Safety Team Act, the National Institute of Standards and Technology (NIST) investigated the May 22, 2011 tornado in Joplin, Missouri. The investigation was an effort to characterize (1) the wind environment and technical conditions associated with fatalities and injuries, (2) the performance of emergency communications systems and the public response to such communications, and (3) the performance of residential, commercial, and critical buildings, designated safe areas in buildings as well as lifelines. The final report of the investigation concluded with a list of sixteen recommendations, including but not limited to recommendations for action on emergency communications. Specifically, NIST recommended "the development of national codes and standards and uniform guidance for clear, consistent, recognizable, and accurate emergency communications, encompassing alerts and warnings, to enable safe, effective, and timely responses" [1, p.367]. This Technical Note is the third installment in the NIST effort to develop evidence-based guidance on the creation and provision of public alerts. The first publication in this series, "Outdoor Siren Systems: A review of technology, usage, and public response during emergencies," provided both an outline on the current status of outdoor siren systems in the U.S., as well as a literature review of how people respond to these systems [2]. The second Technical Note, "A review of public response to short message alerts under imminent threats," focused on short message alerts, underscoring best practices as well as strategies geared towards improving message design and delivery, based on the methods by which people receive and process these types of alerts [3]. In this publication, first we present an overview of current popular social media platforms and the capabilities that they feature, as well as their potential applications for emergency management. That is followed by an outline of social media use for disaster response and recovery research findings, organized by themes. The response themes relate to: 1) the use of these tools for formal emergency management, 2) innovative social media applications for disaster response, and 3) how the general public uses these platforms. The recovery themes involve: 1) social media during recovery for mental health, 2) recovery assessment, and 3) relationship development post-event. The research findings are followed by the limitations and practical considerations for emergency managers, as well as future research suggestions.
