★Invited Papers
Keywords:geopark, flood, earthquake, tsunami
In the Nanki Kumano Geopark area which located southern part of the Kii Peninsula, it has suffered from “floods” caused by heavy rain and “earthquakes and tsunamis” caused by subductions at Nankai Trough. I will introduce the geohazards and the wisdom of ancestors in our area.
1. Heavy rain disaster
Floods and landslides caused by heavy rain have occurred repeatedly in the same area due to topographic factors. For example, the “Hitari” district in the southeastern part of the Kii Peninsula is an area where floods have frequently occurred. “Hitari” means that the land is submerged in Japanese. There are many other place names that remind us of floods and landslides. Here, we will introduce the wisdom of ancestors make provisions against Geohazard by place name. In addition, we will introduce the wisdom of farming in places with little flat land and flood control to protect people's lives from floods.
2. Earthquake and tsunami disaster and tsunami monument
Our area is very close to Nankai Trough where the plate subduction zone, people have been damaged by earthquakes and tsunamis. It has 29 monuments that convey the record of tsunamis in four towns, our area, and 24 of them are tsunami arrival records. However, even if houses swept away by the tsunami, it is not unusual to build houses in the same place. In fact, there are many cases where people still live around the tsunami monument. We will introduce the distribution of these tsunami tradition monuments, the local industry, and the lives of people since the Great East Japan Earthquake, 2011.
