Description

<p>Hazard Map (HM) is one of the non-structural measures for the disaster prevention. It is developed for various Disasters. In addition, there were a lot of previous studies about HM. And it was pointed out in these studies that there are few residents who read HM.</p><p>However, most of them studied for residents who read HM. Therefore, there is little knowledge about actual reference and keeping states conditions of HM of residents. In this paper, we grasp the actual reference and keeping states conditions of HM of residents. And we suggest the standard about the ratio of residents who read and keep HM.</p><p>We carried out meta analysis about the actual reference and keeping states conditions of HM using data of plural surveys. As a result, we clarified a correlative between a personal attribute and HM reference condition. The ratio of residents who read HM for elderly people is higher than it for young people. Then, we performed the multiple regression analysis to analyze the influence that factors of “Local characteristic” and factors of “Survey” gave in HM reference condition. In this analysis, we use the ratio residents who are under 49 years old as factor of “Local characteristics”, and the “Term” and “Response rate” as factors of “Survey”. “Term” means the term from the date when HM was published to the date when the survey was carried out. “Response rate” means the response rate of survey which was carried out to investigate actual reference states conditions of HM. As the result of analysis, we clarified relations that the ratio of residents who did not read HM was low at the long “term” region and the high “response rate” region.</p>
