In disaster situations, Twitter has become the preferred means of transmitting information to the news media and the public. This study examines the inter-relationship among the various parties who share and produce information in a disaster situation. Student case studies of disaster situations serve as the primary database for analysis. A preliminary examination of the case studies and the Twitter trails of information seem to support the view that Twitter can be a source of gathering and relaying information in a disaster situation and that first-responder agencies, the media, and the informed public can use Twitter for information they can use in decision making.
