The 2011 off the Pacific coast of Tohoku Earthquake caused extensive damage from the tsunami disaster, mainly in coastal areas, in addition to the collapse of buildings caused by the earthquake. Ten years have passed since the earthquake, and reconstruction of the affected cities are underway. However, reconstruction plans hastily formulated after the earthquake have resulted in a mismatch between residential and industrial areas, and in many cities, plans that have erased the history and culture of the city.
The Nankai Trough earthquake, which has a 70% probability of occurring within the next 30 years, is predicted to cause tsunami disaster of the same 2011 over the wide area from Shikoku to nearly Aichi Pref. However, many municipalities including Anan City, the subject of this study, have postponed to promote Pre-disaster Recovery Planning (PRP), which could lead to 2011.
This study hypothesizes that the reason for the lack of PRP is the lack of an "engineering education approach”. The authors considered that the present PRP has only provided fear of tsunamis and has not provided technological solutions such as architecture, civil engineering, and urban planning. Therefore, in the Tachibana district of Anan City, where the risk of tsunami disaster is extremely high, this study proposes new PRP to relocate residential and industrial areas currently located in the coastal area to inland areas and turn the coastal area into a coastal park. This plan is intended to increase tsunami safety and maintain industrial and cultural sustainability.
This paper describes the effectiveness and challenges of the engineering education approach by presenting the proposed plan to residents of the Tachibana area, including elementary school students, interviewing them, and organizing them through qualitative research methods.
