Does the provision of emergency information on social media facilitate citizen participation during a disaster?

While public management has investigated how citizens participate in disasters, few studies have examined how public organisations encourage citizens to communicate on social networking services (SNSs). To fill this gap, this research investigates how public organisations provisioned information to help citizens participate more during a disaster response. We analysed the 2013 Seoul Emergency Management Survey to highlight how organisations communicated more effectively during the 2013 Seoul Floods and implies that SNS can help organisations share information and communicate decisions in emergency situations. The findings support the hypothesis that governments can share and provision information on SNS to positively affect citizen participation in a disaster. This research concludes with the notion that public organisation can use SNS not only to transmit information but also to reduce uncertainty by facilitating citizens to participate in risk communication on SNS.
