新闻和警报是社会备灾的关键组成部分，因为它们补充规划和业务协调。社交媒体越来越成为用户在这些事件中传播有用的公共安全和紧急信息的手段。有影响力的用户的出现在改善在线社交网络以广泛传播信息方面起着至关重要的作用。这项研究的重点是Twitter上有影响力的个人用户的出现，并探讨他们在最具破坏性的灾难之一：飓风哈维期间获得大量追随者的原因。新兴影响者的追随者增加的不同模式可以分为几种类型。在这些类型中，以明确的语言和一致的方式发布客观的灾害相关信息的Twitter用户往往会增加追随者，并成为有影响力的用户。此外，来自媒体行业、公共机构和部门以及研究组织的专业人员在飓风期间为公共信息和预警做出了重大贡献。调查结果突出了新兴的有影响力的社交媒体用户的共同属性，以及他们在自我组织的灾害信息传播中发挥的关键作用。
Public information and warning represent key components of society's disaster preparedness, as they complement planning and operational coordination. Social media has increasingly become a means by which users spread useful public safety and emergency information during these events. The emergence of influential users plays a critical role in the improvement of online social networks for widespread information diffusion. This study focuses on the emergence of influential individual users on Twitter and explores the reason why they achieved a significant number of followers during one of the most devastating disasters: Hurricane Harvey. The diverse patterns of increases in followers for the emerging influencers may be separated into several types. Among those types, Twitter users who posted objective disaster-related information in clear language and a consistent fashion tended to show an increase in followers and emerged as influential users. Additionally, professionals (from the media industry, public agencies and departments, and research organizations) made significant contributions to public information and warning during the hurricane. The findings highlight the common attributes of emerging influential social media users and the crucial role they play in the self-organized dissemination of disaster information.
