Research on promoting the effectiveness of evacuation planning against volcanic eruption

在这项研究中，我们在大岛进行了大规模调查和深度访谈，在不久的将来可能发生火山爆发。大规模调查的目的是明确火山学家的图像与当地政府或居民的图像之间的任何差距。深度访谈的目的是澄清必要的准备工作和/或工作，以减少伴随疏散的经济损失。结果表明，虽然火山学家、当地政府官员和居民对喷发可能性、喷发类型等方面的认识不存在形象差距，但疏散行动对警戒级别的过度依赖。为了在短时间内进行疏散，需要对疏散计划进行详细的讨论。高发季节一般在11月，温室养殖户在短时间内通过连续的日常作业可以略微减少危害。在此基础上，与当地政府官员进行了一些讨论，并与居民举行了会议。

In this study, we conducted a mass-survey and depth interviews in Oshima Island where a volcanic eruption may be occurred in near future. The aim of mass-survey was to specify any image gaps between those of the volcanologists and those of local government or residents. And the aim of depth interviews was to clarify the necessary preparations and/or works that could reduce the economical damages accompanied with evacuation.The result showed, although there was not image gap between the volcanologist, local government officer and residents on the eruption possibility, eruption types, so on, over-dependency of evacuation operation on the alert level. And in order to evacuate in short time, the evacuation planning should be discussed in detail. Generally high season was November, and greenhouse farmers may reduce the damage slightly by continuous daily working in a short time.Based on result, some discussions was made with local government officers and meeting with residents was held.
