Keywords:2024 Noto Peninsula earthquake, tsunami evacuation, difficult-to-evacuate areas
In the 2024 Noto Peninsula Earthquake on January 1, 2024, a tsunami was observed over a wide area on the coast of the Sea of Japan. This study aimed to clarify the characteristics and issues of tsunami evacuation in Minato-cho 1, Naoetsu, Joetsu City, Niigata Prefecture. In this study, we conducted interviews with neighborhood associations, disaster prevention specialists, and Joetsu City’s Crisis Management Division, as well as a questionnaire survey of residents. We also analyzed possible evacuation areas and difficult-to-evacuate areas using a Geographic Information System (GIS).
At the time of the disaster, many residents evacuated. The reason for the evacuation was suggested to be a high level of disaster prevention awareness, based on the proactive activities of disaster prevention specialists of neighborhood associations. It was also suggested that images of the tsunami disaster at the time of the 2011 off the Pacific coast of Tohoku Earthquake influenced evacuation decisions. In addition, more than half of the people evacuated by car. However, the results revealed the existence of difficult-to-evacuate areas and issues with evacuation by car.
The target area is expected to experience larger earthquakes and tsunami in the future. It is expected how to improve evacuation behavior, but evacuation issues such as delays in starting evacuation have remained.
