[MIS28-P04] Consideration on problems and classification methods of "Disaster Monument"

Keywords:Disaster, Monument, Classification

In recent years, research on monuments related to natural disasters has been actively conducted. The Geospatial Information Authority of Japan added the disaster monument to the map symbol. It is hoped that the monuments about disasters will tell the past disasters. However, the debate on how to organize and classify monuments is delayed. From the perspective of disaster prevention, it is important to convey past natural disasters, and they do not necessarily have to be stone monuments. For example, some trees and faults have the function of handing down disasters. If you stick to the shape too much, you may lose essence.
Unless the nature of the monument is clarified, it may not be possible to properly preserve and use it. The stele indicating the depth of the flood should not be moved easily. Steles about the dead must be treated with dignity. Therefore, appropriate classification needs to be performed.
In this study, we thought that it was necessary to set a higher-level concept to analyze the monument. Next, the monuments were classified into those that describe the disaster by text and those that do not use text. Some monuments that do not use text do not reveal the relationship to the disaster just by looking at them. In addition, there are potential monuments in which the relationship with the disaster has not been scientifically clarified. These are likely to be forgotten unless a connection with the disaster is proved or explanations are provided. The classification method shown here is a private idea. Many researchers' discussions are needed to solve various issues.

This research was conducted as part of the Research Grants for Young Researchers of the Association for Disaster Prevention Research.
