Witnessing in crisis contexts in the social media age: the case of the 2015 Tianjin blasts on Weibo

This study explores how the act of witnessing takes distinctive discursive shape in social media in the context of large-scale disasters or crisis events. Drawing upon a set of microblogs posted on China’s most widely used social media platform, Weibo, immediately after one of China’s most serious industrial accidents, this study shows how witnessing manifests itself through individual eyewitness accounts foregrounding personal experience but constrained within Weibo’s standard protocol of 140 Chinese characters. Often blending word and image, these accounts are examined using methodologies drawn from discourse analysis. On this basis, we argue that witnessing in social media in China not only demonstrates strong participatory, connective, and self-reflexive characteristics. It also opens up new possibilities for various patterns of meaning, which, when appropriated by other social media users, constitute a public testimony that can challenge official discourses of crisis in China.
