LIOTARD, Alan et al. Risk perception of tsunamis at Sines, Portugal: the importance of landscape in social risk perception. Finisterra [online]. 2017, n.105, pp.29-47. ISSN 0430-5027.  https://doi.org/10.18055/Finis8561.

ASTARTE is a research program that aims to improve the resilience of European populations to tsunamis. A survey at the European scale was conducted during 2014-2015 on several coastal sites at risk of tsunamis. This article presents a few results by questioning the role that a regular, even daily, perception of a rough sea landscape - here the Atlantic Ocean, on the Portuguese coast of Sines - can play in the identification of a “tsunami landscape” and in the spontaneous behavior of people. The role of the landscape in the social perception of the risk was assessed by questioning a sample of individuals - directly on the littoral field - putting them into situation by showing multiple pictures of maritime scenes (tsunamis, storms and low tide). People inquired were asked to assess the level of risk they perceived on each picture. The main conclusion is that tsunamis' waves apprehended through pictures during the survey were perceived as a less risky situation than those showing storm waves. Thus in Portugal, the importance of precursor signs should be better considered in awareness campaigns rather than the height of the waves. This article aims to show why it is important to take the « landscape » factor into consideration for awareness campaigns
