Development of a Geographical Information Method on Inhabitants'Disaster Risk Perception and Application of it to Improve Disaster Damage Reduction Measures

为了建立居民灾害风险感知的地理信息方法，我们进行了两次调查。其中一项是对2011年在太平洋沿岸发生的东北大地震造成巨大液化和破坏的茨城县伊塔科市日野区居民进行问卷调查，另一项是对茨城县大井町大井阳光海滩海滨游泳区的游客进行访谈调查。基于所获得的数据，我们分析了居民迁出/继续居住的意愿和游客在海啸中撤离行动的意愿。

In order to contribute to develop a Geographical Information Method on Inhabitants' Disaster Risk Perception, we conducted two surveys. One was a questionnaire survey on inhabitants in Hinode district, Itako city, Ibaraki prefecture where tremendous liquefactions and damage occurred due to the 2011 off the Pacific coast of Tohoku Earthquake, and the other was a interview survey on visitors to Oarai Sun Beach seaside swimming area in Oarai town, Ibaraki prefecture. Based on obtained data, we analyzed about the inhabitants’ intention of moving from/continuous habitation in thedistrict and the visitors’ intention of evacuation action from Tsunami.
