"Information sharing between public safety organizations and communities is critical in emergency situations, especially large-scale events such as floods, earthquakes, and hurricanes. In recent years, according to the U.S. Department of Homeland Security (DHS), 'Social media and collaborative technologies have become critical components of emergency preparedness, response, and recovery.' Through the use of social media, members of the public who witness incidents can provide public safety organizations with timely, geographic-based information. This information can be used by decision-makers in planning response strategies, deploying resources in the field, and, in turn, providing updated and accurate information to the public. [...] The purpose of this report is to provide an overview of current and innovative social media strategies used by public safety organizations to engage interactively with the public during all phases of emergency situations. The information presented here was obtained from an Internet-based literature review and case study interviews conducted on-site and by telephone."
