Study on Vicissitudes of Dwellings and Settlements due to Disasters

本研究的目的是为了弄清住宅和聚落的变迁对防灾减灾的影响。首先，对沿着三陆沿岸地区因海啸而导致的聚落迁移进行了研究。研究结果显示，海啸对房屋的破坏程度与是否拆除有关。一个小的或大规模的村庄在灾害发生后无法搬迁。拆除定居点有效地减轻了该地区下一次海啸的破坏。然而，很难明确拆迁模式与房屋受损的关系。第二，我们调查了1974年伊豆半岛地震后房屋受损的重建情况。在本研究中，我们无法明确房屋损坏与房屋拆迁之间的关系。

The purpose of this study was to clarify the effect of vicissitudes of dwellings and settlements for natural disaster mitigation and prevention.At first, the removal of settlements caused by tsunami along the Sanriku coastal area was studied. As a result of this study, a grade of housing damage due to tsunami was concerned to remove or not. A small or large scale village could not remove after disasters. The removal of settlements were effective to mitigate the next tsunami damage in this area. However, it was difficult to clarify the relationship between removal patterns and damage.At the second, we investigated on reconstruction of housing damage caused by the 1974 earthquake off the Izu Peninsula. We could not make clear relationship between the damage of housing and removal of housing in this study.
