GNGTS 2023 - Atti del 41° Convegno Nazionale

Session 2.3 GNGTS 2023 2022): one of the most puzzling questions is to identify different publics’ needs, information collection strategies and favourite channels as to gain attention and to build trust. Our study is aimed at providing an analytic segmentation of a representative sample of Italian population (N = 1500) to identify and classify different recipients’ profiles and their communicational needs in order to carry out a well-tailored tsunami risk communication strategy. We try to identify different groups with homogeneous characteristics and then better address points of strength, weakness and blind spots. Multivariate statistical methods are used in order to identify homogeneous groups or profiles of respondents with respect to behaviour relating to the effectiveness of tsunami risk communication. In particular, the study focuses on the critical publics, namely those groups being characterised by a lower level of risk perception and more limited knowledge, with the aim of highlighting the critical factors that can hinder communication (including, for example, educational degree, region, distance from the sea and choice of channels used to obtain information) and possible strategies to be implemented in the dissemination of messages to counteract perceptual biases and false beliefs.
