The 2011 disaster at Japan's Fukushima-Daiichi nuclear power plant poses important questions for environmental communication scholarship and practice. This forum examines questions that were emerging one month into the Fukushima crisis, when a panel examined its implications as part of North Carolina State University's second annual research symposium on Communication, Rhetoric, and Digital Media (details available at http://crdm.chass.ncsu.edu/symposium2011/). Expanding those initial analyses, we identify implications across the contexts of environmental communication, expert-public engagement, public discourses of nuclear energy, uses of new media, risk and crisis communication, and organizational and institutional communication. The first essay (Kinsella) addresses some implications of Fukushima from the perspectives of constitutive communication theory, risk analysis, and risk communication. The second essay (Ionescu) examines an effort to foster dialog between technical experts and a concerned public audience, made by a nuclear energy institute in Germany. The third essay (Binder) explores uses of Twitter by people in the USA as a tool for following the rapidly evolving events at Fukushima. The final essay (Kittle Autry and Kelly) analyzes public discourse surrounding a proposed merger of two US energy companies with substantial nuclear operations, before and after the onset of the Fukushima disaster.
