This research explored how we can improve tsunami evacuation behavior, which has been a major social issue since the 2011 Great East Japan Earthquake and Tsunami. We introduce Nige-Tore, a smartphone app for supporting tsunami evacuation drills, which was developed within an interdisciplinary research framework. Nige-Tore serves as an effective interface tool that successfully visualizes the dynamic interactions between human actions (evacuation behavior) and natural phenomena (tsunami behavior). Drill participants can check, on their smartphone, the estimated inundation area of the approaching tsunami, along with their own current evacuation trajectory. The results of real-world trials using Nige-Tore show that the app is more powerful than conventional devices and methods that have been used in tsunami evacuation training, such as hazard maps and traditional drills that do not make use of any apps, because Nige-Tore provides an interface that enables commitment and contingency thinking—which at first glance appear to represent different orientations—to not only coexist but to synergize. “Commitment” (devotion or involvement) refers to the act of immersing oneself in and viewing as absolute one particular scenario or its potential to be actualized, given conditions in which infinite scenarios may be actualized, depending on the interactions between human systems and natural systems. “Contingency” thinking (an accidental or incidental state) refers to the act of relativizing and separating oneself from any particular scenario or its potential to be actualized, given the same conditions. The synergistic effect of “commitment” and “contingency” thinking also expands people’s capacity to cope with unexpected and unforeseen events.

这项研究探索了如何改善海啸避难行为，自2011年东日本大地震和海啸以来，这一直是一个主要的社会问题。我们介绍Nige-Tore，这是一个在跨学科研究框架内开发的，用于支持海啸疏散演习的智能手机应用程序。Nige-Tore是一种有效的界面工具，可以成功地可视化人类行为（撤离行为）与自然现象（海啸行为）之间的动态交互。演习参与者可以在其智能手机上查看即将到来的海啸的估计淹没面积，以及他们当前的疏散轨迹。使用Nige-Tore进行的现实世界试验结果表明，该应用程序比海啸疏散训练中使用的常规设备和方法功能更强大，例如危险地图和不使用任何应用程序的传统演习，因为Nige-Tore提供了一个界面，使承诺和应急思想（乍一看似乎代表了不同的方向）不仅可以共存，而且可以协同工作。“投入”（奉献或参与）是指在一定条件下可能实现无限场景的情况下，完全沉浸在一种特定场景或其绝对可能实现的行为，具体取决于人类系统与自然系统之间的相互作用。“应急”思维（偶然或偶然的状态）是指在相同条件下使自己与任何特定方案或可能实现的潜力相对立和分离的行为。
