    Community preparedness for natural hazards in two Chilean coastal cities
    (2024) Castaneda, Javiera V.; Repetto, Paula B.; Bronfman, Nicolas C.; Cisternas, Pamela C.
    Chile is a country with high exposure to earthquakes and tsunamis. However, cities present different levels of community preparedness. Understanding the decision-making process for adopting preparedness measures is essential to motivating community participation while considering the local needs of each city. Considering the Protective Action Decision Model (PADM) to understand community preparedness, this study explores the role of risk perception, risk awareness, and trust in authorities in community preparedness in two coastal cities in Chile. A sample of 1093 inhabitants of two coastal cities, Valpara & iacute;so and Concepci & oacute;n, participated in the study. The results indicate significant differences between coastal cities' preparedness levels and their determinants, particularly risk perception and awareness. Despite these differences, our results show that trust in authorities is related to Chile's community preparedness levels in both locations.

    The influence of risk awareness and government trust on risk perception and preparedness for natural hazards
    (WILEY, 2023) Cisternas, Pamela C.; Cifuentes, Luis A.; Bronfman, Nicolas C.; Repetto, Paula B.
    Risk perception is considered the primary motivator for taking preparedness actions. But people with prior experience and a high-risk perception are not necessarily more prepared. This relationship is even more complex when assessing preparedness levels for hazards with different characteristics. These inconsistent findings can be explained by how preparedness has been measured and the influence of other factors, such as trust and risk awareness. Thus, the main goal of this study was to analyze the role of risk awareness and trust in authorities on risk perception and intention to prepare for natural hazards in a coastal city in Chile. A representative sample of the city of Concepcion, located in the center-south zone of Chile (n = 585), completed a survey. We measured risk awareness, risk perception, trust in authorities, and intention to prepare for two hazards: earthquakes/tsunamis and floods. Through structural equation models, we tested five hypotheses. We found that the perception of risk maintained a direct and positive influence on the intention to prepare for both hazards. The results showed that awareness and risk perception influence the intention to prepare and should be considered different concepts. Finally, trust did not significantly influence risk perception when faced with known hazards for the population. Implications for understanding the relationship between risk perception and direct experience are discussed.
