Living in the shadow of ‘Iddu’, the Stromboli volcano, requires a unique cultural adaptation. This study explores the risk perception of the permanent residents of Stromboli Island (Italy), a complex multi-hazard environment where persistent volcanic activity coexists with tsunami threats. Adopting a qualitative design based on 17 semi-structured interviews and focus groups (May 2024), we analysed residents’ narratives through the Cultural Theory of Risk. The findings reveal a hybrid risk culture: a dominant individualistic orientation (37%), driven by self-reliance, is balanced by a strong egalitarian ethos (33%) rooted in community solidarity. The analysis highlights three critical dynamics: (1) the normalization of volcanic risk versus the fear of rare tsunami events; (2) a ‘Trust Gap’ between the community’s horizontal preparedness strategies and the institutions’ vertical communication protocols; and (3) an ‘Economic Filter’ imposed by tourism, which creates a cognitive dissonance where risk is privately acknowledged but publicly downplayed. The study concludes that effective Disaster Risk Reduction (DRR) cannot rely solely on top-down technology but must integrate local knowledge and participatory approaches to bridge the distance between scientific monitoring and community experience.

This article explores the psychosocial dimensions associated with the study of natural hazards, focusing on research activities and key experiences gained during Italy’s major seismic emergencies from 2009 to the present. Particular attention is given to the perception of seismic and tsunami risks, based on research conducted by the Istituto Nazionale di Geofisica e Vulcanologia (INGV) in Italy since 2012. The article examines the memory of past disasters and its role in fostering community awareness of the natural hazards that affect their regions. It also highlights INGV’s initiatives, including risk awareness campaigns targeting citizens and educational programs designed for schools. Furthermore, the seismic emergency information interventions conducted during the three most recent large-scale emergencies—Abruzzo (2009), Emilia-Romagna (2012), and Central Italy (2016–2017)—are presented. These emergency information activities not only meet the need for reliable information and counter misinformation but also offer opportunities for psychoeducational interventions. Ultimately, these efforts aim to offer psychosocial support and promote the restoration of local social networks. The themes discussed contribute to the development of effective strategies and actions for risk reduction.

This study focuses on the risks that tourists would face during a tsunami on the island of Stromboli and discusses how to best inform and prepare them. Tsunamis affect coastal regions, where many of these are leisure destinations for tourists who often don’t have adequate knowledge of the region's risks. Due to their proximity to the affected areas, near-source or local tsunamis usually allow for a limited warning time, posing great challenges to the planning of effective risk mitigation action. Furthermore, tourist populations have a particular significance in studies on risk perception, since their needs intersect with those of the local population and must be taken into account. To gather key knowledge for developing robust risk communication strategies, a survey (n = 699) was conducted between July and October 2023 to assess tourists' risk perception and preparedness. The findings indicate that tourists often misdescribe tsunamis, leading to underestimation of the security threats posed by smaller events and revealing shortcomings in current communication approaches. Given the tourism industry practices on the island, effective communication strategies for tourists should prioritize providing comprehensive information within the first 24 h of their arrival. Furthermore, given the high percentage of tourists who visit the island for a few hours and within certain time slots, we invite the authorities to provide this information before disembarking on the island.

The Tsunami Alert Centre of the National Institute of Geophysics and Volcanology (CAT-INGV) has been promoting, since 2018, the study of tsunami risk perception in Italy. Between 2018 and 2021 a semi-structured questionnaire on the perception of tsunami risk was administered to a sample of 5842 citizens residing in 450 Italian coastal municipalities, representative of more than 12 million people. The survey was conducted with the computer-assisted telephone interviewing (CATI) methodology, described in Cerase et al. (2019), who published the results of the first pilot survey (about 1000 interviews). The large sample and the socio-demographic stratification give an excellent representation of the resident population in the surveyed Italian coastal municipalities. Moreover, in 2021 an optimized version of the questionnaire was also administered via Telepanel (a tool for collecting proportional and representative opinions of citizens) that was representative of the Italian population and included 1500 people distributed throughout the country. In this work we present the main results of the three survey phases, with a comparison among the eight surveyed regions and between the coastal regions and some coastal metropolitan cities involved in the investigations (Rome, Naples, Bari, Reggio Calabria, and Catania). Data analysis reveals heterogeneous and generally low tsunami risk perception. Some seaside populations, in fact, show a good perception of tsunami risk, while others, such as in Apulia and Molise, reveal a lower perception, most likely due to the long time elapsed since the last event and lack of memory. We do not find relevant differences related to the socio-demographic characteristics (age, gender) of the sample, whereas the education degree appears to affect people's perception. The survey shows that the respondents' predominant source of information on tsunamis is the television and other media sources (such as newspapers, books, films, internet), while the official sources (e.g., civil protection, local authorities, universities and research institutes) do not contribute significantly. Also, we find an interesting difference in people's understanding of the words tsunami and maremoto, the local term commonly used in Italy until the 2004 Sumatra–Andaman event, which should be taken into account in scientific and risk communication. The Telepanel survey, based on a nationwide sample, highlights a lower level of tsunami risk perception in comparison to average risk perception levels found in the coastal-municipality sample. Our results are being used to drive our communication strategy aimed at reducing tsunami risk in Italy, to activate dissemination and educational programs (data driven), to fill the data gap on tsunami risk perception in the North-Eastern Atlantic, Mediterranean and connected seas (NEAM) area, and to implement multilevel civil protection actions (national and local, top-down and bottom-up). Not least, outputs can address a better development of the UNESCO Tsunami Ready program in Italy.

This study was carried out as part of the international cooperation project “Agua Futura” for the improvement of water resource management and the promotion of water, sanitation, and hygiene (WASH) behaviors in rural communities of Central America. Given the relevant healthcare problem of water pollution, especially in El Salvador, the aim was to detect some key factors affecting the perception of water contamination and its risky consumption from a community clinical psychological perspective. Ninety rural inhabitants of El Salvador were administered a structured interview exploring their perceptions about water quality and the impact of water consumption on health. Data were analyzed through a computer-aided thematic analysis—complemented by a qualitative analysis—allowing the detection of sense-making processes based on lexical variability. Different themes were identified with regard to the perception of water quality (i.e., mistrust, danger, and safety) and the beliefs about the impact of water consumption on health (i.e., rationalization, denial, awareness, displacement, and isolation of affect). The results showed heterogeneous perspectives about water quality and sanitation. However, the perceived negative impact of water consumption on health was mostly denied or minimized through massive distortions. Overall, the study highlights the role of defensive patterns in facing issues of water contamination, which may prevent the community from adopting healthy behaviors and adequate water management behaviors.

The tsunami risk perception survey is promoted by the Tsunami Alert Centre of the National Institute of Geophysics and Volcanology, operating within the Italian System for Tsunami Alert (SiAM) with the Civil Protection Department and ISPRA, and acting as Tsunami Service Provider in the NEAMTWS.Conducting studies on tsunami risk perception is important in order to obtain data on population’s knowledge and awareness, and understanding people’s perception of tsunami risk. These data are going to be added to those from two previous surveys on tsunami risk perception being issued in 2018 and 2020, to integrate the available knowledge on these issues and will provide publics, experts and policy makers with relevant tools to implement risk mitigation policies. The third phase of the survey was completed in January 2021, administering a total of 4,207 questionnaires to the population living on the coastal areas of Sicily, Campania, Latium and Sardinia, in addition to the 1,635 interviewees considered in previous surveys.The survey used a semi-structured questionnaire consisting of 27 items, with closed alternative questions, and four sets of Likert scale questions. The questionnaire was optimized for CATI administration, taking into account the need for conciseness and comprehensibility of the questions.All the studied regions are located in the central Mediterranean basin (including central and southern Tyrrhenian Sea, Sardinian Sea, Sicily Channel), some of which are characterized by high tsunami hazard, and in some cases they have been affected by recorded tsunamis in a close or distant past. Some regions are located in areas where potential seismic tsunami sources are present, others surround waters where active volcanoes exist, both on islands (such as Stromboli, Vulcano) and below the sea (Marsili, Palinuro). In addition, the four studied regions have a high risk exposure due to the high density of population living on, or visiting the coastal areas for tourism. In the areas where the questionnaire was administered, five highly populated regional capitals are located, including Palermo, Messina, Naples, Rome and Cagliari, together with other important towns (such as Catania, Siracusa, Trapani, Salerno, Olbia etc.). Moreover, the coastal shores involved in the survey, live of a significant tourist affluence in the summer period (and not only), with many tourist facilities and large hotels located along the coasts.The survey's main aim is to analyze the perception of tsunami risk by the coastal population and to correlate levels of tsunami risk perception with scientific data from probabilistic tsunami hazard assessment (PTHA) for the considered coastal area. We will present some preliminary results of this last survey, with a comparison with the previous analyses on other regions in southern Italy.

The Italian Tsunami Alert Centre of the Istituto Nazionale di Geofisica e Vulcanologia (Centro di Allerta Tsunami, hereinafter CAT-INGV) supported a computer-assisted telephone interview (CATI) survey to investigate tsunami risk perception in two pilot regions of southern Italy. The survey was carried out on a stratified sample of 1021 interviewees representing about 3.2 million people living in 183 coastal municipalities of the two regions, namely Calabria and Apulia. The main goal of this research is to verify whether and how people's perception of tsunami hazard compares to the results of (PTHA) – probabilistic tsunami hazard assessment (TSUMAPS-NEAM project; Basili et al., 2018). As shown by the results of this project, both investigated regions are characterised by high tsunami hazard. Nonetheless, the long return time of such events could lead people to consider the occurrence of a tsunami in the Mediterranean Sea to be very unlikely. The survey results reveal that people's risk perception is low: for almost half of the whole sample the occurrence of a tsunami in the Mediterranean Sea is considered quite unlikely, with a clear difference between Apulia and Calabria. In the latter region the risk perception is much higher than in the former, probably due to the shorter time elapsed since the last event. Also, belonging to different coastal areas ¹ appears to have a significant influence on the way tsunami hazard is conceived, having a stronger effect on risk characterisation: the interviewees of Tyrrhenian Calabria are indeed more likely to associate tsunami risk with volcanoes than the Ionian citizens. This is coherent considering the presence of active volcanoes and related tsunami precedents in the Tyrrhenian. Television emerged as the most relevant source of knowledge for almost 90 % of the sample, and the influence of media also results in the way tsunami risk is characterised. In particular, the survey showed that people's perception and understanding of tsunamis are affected by media accounts of large events, such as the 2004 Sumatra and the 2011 Japan tsunamis. At the same time, it is evident that the risk posed by smaller events is underrated. Furthermore, the survey's results show that the word “tsunami” occupies a different semantic space in comparison to the Italian traditional headword maremoto, with differences among sample strata. In other words, the same physical phenomenon would be understood in two different ways by younger, educated people and elders with a low education level. The results of this study, although limited to two regions, provide a first assessment of tsunami risk perception in Italy, also entailing important consequences for both risk communication practice and mitigation policies.

According to a deep-rooted conviction, the occurrence of a tsunami in the Mediterranean Sea would be very rare. However, in addition to the catastrophic event of Messina and Reggio Calabria (1908) and the saved danger for the tsunami occurred on Cycladic sea in 1956, 44 events are reported in the Mediterranean Sea between 1951 and 2003, and other smaller tsunamis occurred off Morocco, Aegean and Ionian seashores between 2017 and 2018. Such events, that are just a little part of the over 200 historically events reported for the Mediterranean (Maramai, Brizuela & Graziani, 2014) should remind geoscientists, civil protection officers, media and citizens that 1) tsunami hazard in the Mediterranean is not negligible, and 2) tsunamis come in all shapes and colours, and even a small event can result in serious damages and loss of lives and properties. Recently, a project funded by the European Commission (TSUMAPS-NEAM, Basili et al., 2018) has estimated the tsunami hazard due to seismic sources in the NEAM region (one of the four ICG coordinated by the UNESCO IOC) finding that a significant hazard is present in most coasts of the area, particularly in those of Greece and Italy. In such a scenario, where low probability and high uncertainty match with poor knowledge and familiarity with tsunami hazard, risk mitigation strategies and risk communicators should avoid undue assumptions about public’s supposed attitudes and preparedness, as these may results in serious consequences for the exposed population, geoscientists, and civil protection officers. Hence, scientists must carefully shape their messages and rely on well-researched principled practices rather than on good intuitions (Bostrom, & Löfstedt, 2003). For these reasons, the Centro Allerta Tsunami of the Istituto Nazionale di Geofisica e Vulcanologia (hereinafter CAT-INGV) promoted a survey to investigate tsunami’s risk perception in two pilot regions of Southern Italy, Calabria and Apulia, providing a stratified sample of 1021 interviewees representing about 3.2mln people living in 183 coastal municipalities of two regions subjected (along with Sicily) to relatively high probability to be hit by a tsunami. Results show that people’s perception and understanding of tsunami are affected by media accounts of large tsunamis of 2004 (Sumatra) and 2011 (Tohoku, North East Japan): television emerged as the most relevant source of knowledge for almost 90 % of the sample, and the influence of media also results in the way tsunami risk is characterized. Risk perception appears to be low: for almost half of the sample the occurrence of a tsunami in the Mediterranean sea is considered quite unlikely. Furthermore, the survey’s results show that the word tsunami occupies a different semantic space with respect to the Italian traditional headword maremoto, with differences among sample strata. In other words, the same physical phenomenon would be understood in two different ways by younger, educated people and elders with low education level. Also belonging to different coastal areas appears to have a significant influence on the way tsunami hazard is conceived, having a stronger effect on risk characterization, for instance the interviewees of Tyrrhenian Calabria are more likely to associate tsunami risk to volcanoes with respect to other considered coastlines. The results of this study provide a relevant account of the issues at a stake, also entailing important implication both for risk communication and mitigation policies.

Polar sciences represent a unique opportunity for scientific dissemination, not only for importance, multidisciplinary values and relapse of the polar researches, but, mainly, because it addresses and transmits ethical and social values as example of strong integration between human beings and extreme environments.In this frame, the idea to communicate and to share the experience of the scientific research in Antarctica with general public and with pupils is a challenge that a team of INGV researchers, engaged for many years in scientific missions in Antarctica, carries on with great enthusiasm. The initiative contributes to several outreach activities of the Italian National Program for Antarctic Research (PNRA). The present work reports the experience of the laboratory “Expedition to the South Pole”, realized by INGV and addressed to the pupils of the primary school. The laboratory game “Expedition to the South Pole” is based on the role playing method and experiential activities.
