The lack of rapid and effective communication between authorities and citizens during a crisis may lead to unimaginable damage and even lost lives.This thesis aimed at exploring how a government agency uses social media to manage a large-scale crisis through the lens of the social media use strategies such as push,pull,and networking strategy.I conducted a content analysis by using the data collected from the social media accounts of the Ministry of Health in Singapore.The findings indicate that the government agency recognized and implemented all three social media use strategies.In particular,the agency mostly used its social media accounts for the push strategy,especially on Twitter.In addition,the agency tended not to use its social media accounts for dialogic communication with constituents.This study contributes to the existing literature on government social media use in crisis management by finding patterns in government social media use strategies.The findings suggest that the governments may purposely apply specific approaches to managing their social media depending on the needs during a particular crisis management phase and use different social media tools to achieve different crisis communication goals.The study also suggests that to achieve the best results from using social media in crisis management,government agencies could implement a more interactive approach that may help authorities build a proactive relationship with the public.Government crisis management organizations and managers could find this study useful,as it may provide a starting point to consider the effective implementation of social media in crisis management.
