Research on information management for systematization and practical use technology of soil structure using IT technology
1995年兵庫県南部地震、2000年鳥取県西部地震,2001年芸予地震の発生は、我が国が世界でも有数な地震災害の多発国であることとともに、地震被害における地盤条件が大きく影響していることを再認識させた。これらの地震災害からの教訓を十分に認識し、地震被害を低減させ,安全かつ安心できる社会環境を整備して共通のコンセンサスを構築していくことは、現在から将来への重要な課題である。このため地震災害を考える上で基本的で重要な地盤情報は、IT技術を利用しデジタル化して蓄積、管理し有効活用する必要があると考える。従来から、点情報として得られる地盤情報については、多数の点情報を集めて面に広げた分析が求められている。本研究は,GISを活用して面的に広げ震災時の被害予測、震災後の被害実態の解明・復旧活動の支援などに有効利用することを目的としている。The foundation conditions in earthquake damage made a new appreciation of having influenced greatly, as for the occurrence of the 1995 Hyogo southern part earthquake, the 2000 Tottori western earthquake, and the 2001 Geiyo earthquake, have with our country being a frequent occurrence country of an earthquake calamity leading also in the world. It is an important subject from present to the future to fully recognize the teachings from these earthquake calamities, to reduce earthquake damage, to improve safety and the social environment about which he can feel easy, and to build common consensus. For this reason, I think that it is necessary to use foundation information fundamental when considering an earthquake calamity, and important, and it needs to be accumulated, and it is necessary to digitize and manage it, and it needs to use IT technology effectively. The analysis which collected many point information and was extended from the former to the field about the foundation information acquired as point information is called for. This research aims at utilizing GIS, extending in field and using effectively for support of elucidation / restoration activities of the damage prediction in case of an earthquake disaster, and the damage actual condition after an earthquake disaster etc
An urban flood in the kashio river basin
An urban flood is one of knotty problems derived from land development. Taking the Kashio River basin of Kanagawa Prefecture as an example, the relationships between urbanization and flood hazards were historically discussed. It was explained that a flood prevention work in one area affects other areas. The historical change in conditions for flood hazards can be divided into six stages
An introductory note on earthquake damage and measures
A phase of earthquake disaster was divided into four stages. Outlines of each stage were given along with some examples. Also, a variety of measures to counter an earthquake disaster explained in line with its phase. It is emphasized that comprehensive measures are indispensable to mitigate earthquake damage
The cyclone disaster of 29-30 april, 1991 in bangladesh
I carried out field studies on the catastrophe of the April, 1991 cyclone hazard in Bangladesh. Vulnerability to cyclone hazard was discussed from the point of view of both social and physical conditions. Although losses of property and social facilities were larger in 1991 than in 1970, human casualty figures showed the reverse tendency. This fact indicates to the effectiveness of the shelters constructed after the 1970 disaster. Fact-finding on refuge taking behavior and living conditions soon after the disaster are necessary to plan countermeasures in the vulnerable coastal lowlands. Control of population growth and land reformation are indispensable to counter natural hazards in Bangladesh
Refuge-seeking behavior during rain-induced disaster : in the case of four districts damaged by typhoon number 10, 1986
The refuge-seeking behavior of those who were affected by Typhoon Number 10 in 1986 was investigated through field work and a questionnaire survey which were conducted in four study areas whose natural and social conditions differed from one another. Two results were obtained by examining the facts surrounding this refuge-seeking behavior. One is that the heavier the damage in a given region, the lower the refuge ratio was. The other is that a normalcy bias was recognized in every study area. Three factors which related closely with refuge-seeking behavior could be extracted by discriminant analysis on taking refuge. These are the depth of the flood waters, the frequency of participation in training for flood fighting and the number of stories in a house. Several existing articles on refuge-seeking behavior during heavy rains were reviewed in order to examine the results obtained in this study and to generalize the characteristics of human behavior during a flood disaster
