A comprehensive review of online, official, and scientific literature was carried out in 2012-13 to develop a framework of disaster social media. This framework can be used to facilitate the creation of disaster social media tools, the formulation of disaster social media implementation processes, and the scientific study of disaster social media effects. Disaster social media users in the framework include communities, government, individuals, organisations, and media outlets. Fifteen distinct disaster social media uses were identified, ranging from preparing and receiving disaster preparedness information and warnings and signalling and detecting disasters prior to an event to (re)connecting community members following a disaster. The framework illustrates that a variety of entities may utilise and produce disaster social media content. Consequently, disaster social media use can be conceptualised as occurring at a number of levels, even within the same disaster. Suggestions are provided on how the proposed framework can inform future disaster social media development and research.

This study examines the “Twitter election of 2012,” and specifically young citizens’ “social watching” behaviors while live-tweeting a 2012 nationally televised Republican primary debate. We find several important relationships between key demographic, social, and political engagement variables and participants’ social watching activity (frequency of tweeting while watching the debate). We also find important links between tweet content (frequency of candidate mentions in tweets) and debate viewers’ candidate evaluations.

Using an experiment and probability sample of Chicago and Los Angeles adults ( N = 1211), this study tested how tweet characteristics (tone, space) and participant age (younger, middle, older) affected attitudes about tweets from a local newspaper. Results indicate that non-opinionated tweets were perceived as more useful and credible than opinionated tweets, and local tweets resulted in more engagement than national tweets. Younger participants (19–36 years) reported more positive affect, usefulness, engagement, and credibility related to tweets than did middle/older age groups. Younger participants were generally more negative about opinionated national tweets and preferred opinionated local tweets compared with middle/older groups.
