Based on a literature review on factors that explain media effects and previous findings on media coverage and public opinion on nuclear power, this article examines the effects of Fukushima on media coverage and public opinion in Germany in two studies. The first study uses content analysis data to analyse changes in media coverage, and the second one is based on panel survey data to examine attitude changes on an individual level. The results of both studies show changes in media coverage and public opinion on nuclear power. Furthermore, the second study reveals that individual attitude changes cannot necessarily be explained by the same factors as the distribution of attitudes.
