25、corporating a consideration of the deployment of social mediaaround risk and crisis communication by stakeholders and publics rep-resents a considerable research agenda. This would need to attend to,for example, how soci

27、f amplification), how traditional mediainteracts with social media, and, of particular interest to this paper,how particular features of social media platforms enable – or constrain– risk communication and how they might

28、 best be deployed at differentstages in the development and management of a crisis.There has been a great deal of work that focuses on the role of socialmedia and crisis communication more generally as noted in earlyrevi

29、ews of this area (Rains et al., 2014; Veil et al., 2011; Wendlinget al., 2013) and the role of microblogs in this has received sustainedattention with Twitter being highly influential and distinctive. Twitterstarted in 2

30、006 as a brief announcement service where users could fol-low others (with ‘following’ not being a reciprocal relationship).Twitter's conversational features were gradually established to supportuser interactions and

31、 the structuring of information (e.g. Marwick andBoyd, 2013). First, users are enabled to directly address other users orrefer to them in conversations using the symbol ‘@’ (e.g. @XXX). Second,users can ‘retweet’ or repr

32、oduce another user's message in its original ormodified form. Third, users can follow streams of updates through key-words which are thematically organised around the symbol ‘#’(hashtag), which is self-assigned to me

33、ssages by users themselves(e.g. #LondonRiots). In addition, tweets often contain media contentor hyperlinks to other material.Due to these features, Twitter has radically changed the way emer-gency information is sociall

34、y distributed. Without replacing traditionalmedia sources, Twitter has become a virtual space where many Internetusers turn to seek emergency details; tweets might even come fromusers from the epicentre of disasters such

35、 as earthquakes (Murthy,2013). During events that draw attention, tweets can be propagatedon the ad hoc networks of users and quickly reach outside previouslyestablished relationships (Marwick and Boyd, 2013). Network ef
