人们早就认识到，传统媒体在反映风险方面发挥着关键作用，是重要的信息来源，可以影响人们如何看待和应对灾害事件。早期的工作利用风险的社会放大框架（SARF）试图了解专家和外行的风险和模式的风险加剧和衰减与媒体的看法之间的差异。然而，Web 2.0的出现对传统的通信模式提出了挑战。到目前为止，SARF内部对社交媒体及其在风险认知和沟通过程中的作用的考虑有限。在这种背景下，我们专注于社交媒体平台Twitter考虑与灰枯梢病（Hymenoscyphus fraxineus）有关的风险的社会放大; 2012年在英国首次发现时，这是一个引起媒体强烈关注的树木健康问题。我们提出了一个实证分析的25,600 tweets，以探讨人们在Twitter上说什么灰顶枯，谁在谈论它，他们如何谈论它。我们的讨论概述了主题，围绕它谈论灰顶枯的定向，用户的环境关系的重要性和包括链接（URL）到传统媒体报道的作用。我们利用捎带的概念来展示信息是如何根据群体/个人的身份和兴趣进行定制的，并引入框架片段的概念来说明信息是如何被选择并在Twitter上移动的，强调了信息的某些功能。该文件提供了一个详细的考虑的方式，人们和组织同时适当的，建设和传递风险相关的信息。结论是，社交媒体有可能改变SARF最初构想的媒体格局，为风险沟通提出新的挑战。
It has long been recognised that the traditional media play a key role in representing risk and are a significant source of information which can shape how people perceive and respond to hazard events. Early work utilising the social amplification of risk framework (SARF) sought to understand the discrepancy between expert and lay perceptions of risk and patterns of risk intensification and attenuation with reference to the media. However, the advent of Web 2.0 challenges traditional models of communication. To date there has been limited consideration of social media within the SARF and its role in mediating processes of risk perception and communication. Against this backdrop, we focus on the social media platform Twitter to consider the social amplification of risk in relation to ash dieback disease (Hymenoscyphus fraxineus); a tree health issue that attracted intense media attention when it was first identified in the UK in 2012. We present an empirical analysis of 25,600 tweets in order to explore what people were saying about ash dieback on Twitter, who was talking about it and how they talked about it. Our discussion outlines the themes around which talk about ash dieback was orientated, the significance of users' environmental affiliations' and the role of including links (URLs) to traditional media coverage. We utilise the notion of piggybacking' to demonstrate how information is customised in line with group/individual identities and interests and introduce the concept of the frame fragment' to illustrate how information is selected and moved around Twitter emphasising certain features of the messages. The paper affords a detailed consideration of the way in which people and organisations simultaneously appropriate, construct and pass on risk-relevant information. A conclusion is that social media has the potential to transform the media landscape within which the SARF was originally conceived, presenting renewed challenges for risk communication.
