Abstract

In this paper, we consider the transition process of a disaster prevention consciousness and action as a disaster subculture, and present an analytical framework using a mathematical simulation in order to enable quantitative consideration. After an unknown parameters estimation by using a questionnaire survey data, we describe the actual situation in this simulation model, and evaluate an influences imparted to the population ratio of four states related with the disaster prevention consciousness and action by some explanatory variables such as a force of contagion, a move-out ratio, and so on. As a result, we receive valuable suggestions that it is impossible to avoid a fading of the disaster prevention consciousness, and that it is possible to vitalize the disaster prevention action continuously if some social conditions are satisfied.

Vernacular Abstract

本研究では,地域住民の防災意識や防災対応行動の状態の時間経過に伴う変遷過程について,簡便な数理シミュレーションによって記述する分析フレームを提示するとともに,そこでの未知パラメータの値を実態調査データを利用して同定することにより現況再現・感度分析・シナリオ分析を行った.その結果,調査対象地域においては,どのような条件下においても最終的な防災意識の低下は免れ得ないことが示唆されると同時に,ある種の社会条件が整うことにより防災対応行動が持続的に活性化される状況が生じ得ることが示された.
