Vernacular epistemologies of risk : The crisis in Fukushima

On 11 March 2011, an earthquake of a 9.0 magnitude and the consequent tsunami destroyed Japan’s Fukushima Dai-ichi power plant. Known as 3/11 in Japan, the effects of this triple disaster will continue for decades. How did the media covering the catastrophe articulate issues of risk to the general public? This article is a textual analysis of accounts about the Fukushima disaster published between 11 March 2011 and 11 March 2013 in four of the most prominent media outlets in the United States. In particular, the analysis explores the practices through which these US media constructed the presence and meaning of public health risks resulting from the nuclear meltdown. The article illustrates how systematic media practices minimized the presence of health risks, contributed to misinformation, and exacerbated uncertainties. In the process, the study demonstrates how the media created vernacular epistemologies for understanding and evaluating the health risks posed by nuclear radiation. The article concludes by weighing the implications of the vernacular epistemologies deployed by media.
