Communicating tsunami risk and uncertainties

This is Chapter 8 of "Probabilistic Tsunami Hazard and Risk Analysis: A Cookbook". The chapter aims to provide scientists with guidance and background information on how to appropriately engage in, co-design, prepare, and deliver tsunami risk communication, with and to different audiences. Risk communication is not only about classical, typically unidirectional science communication (from science to public or end users), but also about a range of different, multidirectional, interactive, and iterative communication approaches with all relevant actors related to tsunami risks.

The chapter covers the three main pillars of tsunami risk communication and the process of building an effective communication strategy for the respective problem. First, we have to deal with understanding the context of what has to be communicated, by and to whom. Then it comes to the choices of the appropriate methods and tools for risk communication. Last but not least, the evaluation of the effectiveness of the communication process will give indications for possible improvements.
