Exploring the changes in risk perceptions and adaptation behaviors based on various socioeconomic characteristics before and after earthquake disasters – a case study in Taiwan
2020
Abstract. Resilience, which has rapidly become an area of interest in
multiple disciplines, is regarded as being key in disaster mitigation and
adaptation. The objective-indicator framework is a common way to evaluate
resilience, but limited attention has been paid to measuring the risk
perceptions and adaptation behaviors of individuals. In addition, due to
limitations related to predicting potential earthquake events, past studies
have placed more emphasis on predisaster discussions. Fortunately, this
paper explores the changes in risk perceptions and adaptation behaviors in
different socioeconomic groups through a comparative analysis between pre-
and postearthquake disasters and through one-way analysis of variance (ANOVA) with
a post hoc test applied to examine the changes in risk perceptions and
adaptation behaviors. The results show that people tend to have greater risk
perceptions of future earthquakes but are less willing to retrofit their
houses after a serious disaster. Females show greater fear and worry
accompanied by a higher willingness to retrofit their houses compared to
males. In addition, people with a higher education level and a better
occupation might be more willing than others to adopt adaptation behaviors.
The results can serve as
a reference to provide risk communication, risk education, and diverse
disaster adaptation options. Although limitations exist, the results of
comparative analysis between the predisaster and postdisaster conditions
could serve as a reference for adequate strategies and government decisions
on the prioritization of risk management policies.
