This chapter examines the social media use by local governments, and other policy actors (government agencies, non-governmental organizations and citizens) after the 2011 Van Earthquake in Turkey. This study is different from others examining social media use of just one policy actor after a disaster; as it compares and contrasts the performance of different policy actors with that of local governments. To this end, contents of the messages posted on selected Facebook pages after the earthquake are analyzed. The findings include examples of effective social media use for disaster relief and recovery, as well as detailed information about the nature and functioning of "multiple/parallel systems of public service/information delivery", more than one electronic channel of communication and coordination simultaneously connecting people and organizations. The findings suggest that, if institutional arrangements conducive to collaborations are present, social media platforms can be effective means of disaster relief and recovery, especially for communication among citizens after a disaster.
