Abstract

Social media are quickly becoming the channel of choice for disseminating emergency warning messages. However, relatively little data-driven research exists to inform effective message design when using these media. The present study addresses that void by examining terse health-related warning messages sent by public safety agencies over Twitter during the 2013 Boulder, CO, floods. An examination of 5,100 tweets from 52 Twitter accounts over the course of the 5-day flood period yielded several key conclusions and implications. First, public health messages posted by local emergency management leaders are most frequently retweeted by organizations in our study. Second, emergency public health messages focus primarily on drinking water in this event. Third, terse messages can be designed in ways that include imperative/instructional and declarative/explanatory styles of content, both of which are essential for promoting public health during crises. These findings demonstrate that even terse messages delivered via Twitter ought to provide information about the hazard event, its impact, and actionable instructions for self-protection.
