项目摘要

In the study on natural disaster science, locality analyzed wth database is one of two main factors which control the law of natural disaster occurrence. In order to make clear the characteristics of natural disaster, it is necessary to follow the recent changes of some dominant factors of the and locality to predict near future trend in acompany with urbanization. Especially, Tokai, Tonankai and Nankai earthquake disasters may sequentially occurs until 2050 and serious damage in the wide area from Tokai district and westward with seismic ground motion and tsunamis. The overall damage was introduced with Geographycal Information Systems. The maximum tsunami height and the shortest arrival time of the first tsunami are predicted to make tsunami evacuation manuals. The numerical simulation technique is useful to reduce loss of human lives due to quick arrived tsunami. Another main factor is history of occurrence of catastrophic natural disaster. In the study, the Hanshin district suffered from Great Hanshin-Awaji earthquake disaster was examined from the view points of historical disaster. The severely damaged area was overlapped with lawland in the process of formation of coplex fan-shaped landform. In the Kinki district, the excavation of remains shows that large scale flooding changed the social systems due to largeness of damage.

在自然灾害学研究中，利用数据库进行局部性分析是控制自然灾害发生规律的两个主要因素之一。为了弄清自然灾害的特点，有必要跟踪本地区某些主导因素的近期变化，并结合城市化进程，预测近期趋势。特别是东海、东南海和南海地震灾害可能在2050年前相继发生，并伴随地震地面运动和海啸，在从东海地区向西的广大地区造成严重破坏。地理信息系统引入了整体损坏。预测第一次海啸的最大海啸高度和最短到达时间，编制海啸疏散手册。数值模拟技术对于减少海啸快速到达造成的人员伤亡具有重要意义。另一个主要因素是历史上发生的重大自然灾害。本研究从历史灾害的角度考察了遭受坂神淡路大地震灾害的坂神地区。在复杂的扇形地貌形成过程中，严重破坏区与草地重叠。在近畿地区，对遗迹的挖掘表明，由于大规模的破坏，大规模的洪水改变了社会制度。
