Understanding individuals' evacuation decisions is crucial for emergency policy making and long-term social reconstruction. This study identifies five socio-psychological factors that contribute to individuals' evacuation intention under natural hazard conditions, including attitude towards advice, risk perception, social norm, perceived behavioral control, and preparedness intention. Based on these factors, a conceptual framework is proposed and implemented using a structural equation modeling approach. The results support the proposed framework and provide insights into the interrelationships between the predictive factors.
Understanding evacuation decisions of individuals is imperative to establish policies and procedures during emergencies and for long-term societal reconstruction. Five socio-psychological factors contributing to individuals' evacuation intention under natural hazard conditions are identified from a literature review. These include attitude towards advice given by the authorities, risk perception, social norm, perceived behavioural control and preparedness intention. A conceptual framework is proposed based on the socio-psychological approach to model and analyse the evacuation intention. An online behavioural expectations questionnaire survey is conducted in Auckland, New Zealand, to investigate the evacuation decision-making behaviour of Aucklanders under a hypothetical volcanic eruption scenario. The proposed framework is implemented using the structural equation modelling approach. The results support the proposed model and provide some insights into interrelationships between the predictive factors. Psychological factors, including attitude towards advice given by the authorities, preparedness intention and risk perception, have a significant positive impact on individuals' evacuation intentions.
