The relationship between political ideology and current earthquake and tsunami preparedness

Previous studies have revealed that political ideology can influence motivations for individual preparedness to mitigate the effects of climate change. Few studies have examined its role in individual preparedness behaviors to reduce the impacts of other natural hazards, such as earthquakes and tsunamis. The purpose of this study is to explore the influence of political ideology on current individual earthquake and tsunami preparedness behaviors among inhabitants of Chile's coastal areas. A statistically representative sample of the Valparaíso Region (N = 500) participated in this study. They were part of a more extensive study conducted between 2018 and 2019 in cities along the Chilean coastline, intending to study preparedness for multiple natural hazards. The survey evaluated trust in government authorities regarding emergency management, current earthquake/tsunami preparedness behaviors, and political ideology. The results reveal that political ideology is a relevant factor in predicting emergency preparedness behaviors and is significantly related to trust in government authorities. The individuals located on the right extreme of both dimensions of political ideology (those self-identified as right-wing and/or pro-market) report a higher level of current earthquake/tsunami preparedness, compared to their respective groups. Thus, for future design and implementation of natural disaster preparedness strategies and programs, the agencies in charge should recognize the role of political ideology.
