"Videos are commonly used by emergency services agencies in natural hazard emergencies to communicate to the public about the hazard, its possible risks, and to promote protective action. To evaluate the efficacy of the videos being disseminated and amplified during an event, this research examined ... the extent to which different types of videos trigger risk perceptions, promote protective action, and improve knowledge about the hazard and impact. The findings suggest a video containing a smaller number of facts is most useful at impacting the public’s hazard knowledge, visualisations (real-life or infographics) of facts helps improve knowledge, and videos highlighting the impact an emergency is having (or had) through people’s experiences helped improve hazard knowledge, risk perceptions, and protective action intentions. Finally, while footage of a bushfire triggers threat perceptions and some coping appraisal, the style is not as useful for building hazard knowledge. The research extends visual risk literacy knowledge and offers practical guidance for agencies operating in high-risk environments seeking to achieve behavioural compliance. The research argues videos will continue to be an important tool in the public information and warning milieu for any risk event." (Abstract) more

"An online survey was conducted in which participants were exposed to one of 16 mock emergency warnings about either a bushfire or a riverine flood and were then asked a series of questions relating to their demographic characteristics, message comprehension and effectiveness, threat appraisal, copi ... ng appraisal, protection motivation and maladaptive coping behaviour. Mock emergency warnings were developed using existing end-user emergency warnings to improve realism and maximise the usefulness of the findings, as well as building on previous QUT-conducted BNHCRC research (see Greer et al., 2019). A total of 2,482 Australians living across all states and territories were recruited to participate in the research. Participants were recruited by the Market Research firm Dynata. Approximately 150 participants responded to each of the 16 stimuli. Overall, the research results show that adding colours and/or icons to the Evacuate Now (Bushfire) message creates improvements, albeit small ones, in message comprehension, effectiveness, perceived probability and perceived self-efficacy. The other three messages showed no improvement (or loss) in message comprehension, effectiveness, threat appraisal, or coping appraisal as a result of adding colours and/or icons." (Abstract) more
