[O08-P99] Evacuation plan on typhoons, via interviews from victims and disaster management authorities and field investigations
Keywords:weather
Kochi Prefecture, including Muroto City, is known as a typhoon-prone area. The inhabitants of Muroto have long been prepared for typhoons, as can be seen in the 'ishiguro' (stone walls) found in traditional houses in Kiragawa town and concrete walls in the Takaoka area. For example, 1934 Muroto Typhoon, which is named after Muroto, caused extremely heavy damage, with 99 people dead or missing in the area now included in Muroto City. Typhoon Vera (1959) and Typhoon Nancy (1961) also caused extensive damage in Muroto City. Even in the 21st century, there have been major typhoons that caused casualties in Muroto City. Typhoon Tokage (2004) damaged 11 houses and killed three residents in the Nabae area of Muroto City when the typhoon's tidal waves damaged a tide wall and scattered concrete fragments. In Muroto, there are loud calls for damage from the Nankai Trough earthquake, which is certain to occur within a few decades, but damage caused by typhoons also poses a very serious threat to the sustainable development of Muroto City. In this study, therefore, a survey was conducted with the aim of developing an evacuation plan for accurate evacuation in a typhoon approaching. First, interviews were conducted with the persons in charge of the Disaster Prevention Section of Muroto City to collect information on the evacuation plan of Muroto City. Next, interviews were conducted with victims of Typhoon Tokage (2004) about their situation before and after the typhoon attack. Furthermore, the presenters actually walked the evacuation route from their homes to the nearest evacuation center, measured the distance and time required for the evacuation, and verified the possible risks around the evacuation route in the typhoon approaching. Based on these results, this study reports on an evacuation plan formulated to ensure accurate evacuation in the typhoon attack.
