Effective risk communication is essential for disaster risk management.Apart from empowering com-munities to make informed risk choices,risk information disclosure can also drastically enhance their disaster pre-paredness,especially concerning conjoint scenarios of technological and natural hazards(Natech).A fundamental precondition is the actual demand for such information.This study ventures to assess whether residents around Osaka Bay have this demand,or"appetite,"for risk information disclosure,as well as to understand their communicative behavior and perceived challenges in the Japanese context through the prism of the Situational Theory of Problem Solving.To test this framework under realistic conditions,data were collected through a house-hold questionnaire survey from two urban areas near industrial complexes in Osaka Bay.The results show that identifying Natech risk information deficiency as a prob-lem was not a statistically significant predictor for indi-viduals'motivation to communicate.However,their motivation increased as their perceived personal involve-ment with the situation rose,while the perceived obstacles in doing something about it exerted a negative influence on their motivation.Individuals'motivation intensified their communicative actions to solve this problem.Public seg-mentation underscored the elevated public perceptions concerning the issue of risk information deficiency in nearly nine out of ten respondents.These findings indicate a strong community appetite for chemical and Natech risk information,which subsequently led to high situational motivation to engage in communicative action,particularly information acquisition.Risk management policy is sug-gested to focus on introducing chemical risk information disclosure regulatory initiatives to encourage citizen engagement.
