Abstract: Evacuation drills have been developed as part of many risk management programs. However, very few studies have paid attention to the process of evacuation drills. This study employs action research to examine a tsunami risk management strategy called the single-person drill, and applies new technologies in presenting related outcomes presented as multiscreen movies. The drill targets vulnerable people (i.e., older adults), during which a single evacuee moves to a shelter with the aid of a Global Positioning System (GPS) device. Evacuation routes, destination, and duration were used as parameters in an agent-based evacuation simulation shown on movies. The drill has been conducted 58 times in a coastal community (Okitsu, Kochi Prefecture), and 59 multiscreen movies were produced. An analysis of the effectiveness of the drill and related movies was done by collecting both quantitative and qualitative data. Results showed that, with a total of 163 respondents of a semistructured interview, 70.0% of residents were familiar with the drill, and 22.0% wanted to try it. The drill helped elderly people to improve self-efficacy in tsunami risk management, and generated two-way risk communication between experts and participants. This paper contributes new insights into understanding the importance of technology in tsunami risk management.
