Tsunami disaster prevention of Seto Inland Sea is slow to take action for lack of knowledge of generation mechanism of Tsunami damages. According to previous research papers, there is a possibility of appearance of sudden water level raising and long-term water level fluctuation in sympathetic vibration with characteristic vibration in some bay. Therefore, this study focuses on period characteristics and hazardous sea area. As a result of numerical analysis, temporal period characteristics of each sea area, distribution of largest tsunami heights and time of occurrence, distribution of maximum tsunami velocity and time of occurrence and a map of hazardous sea area are clarified. Moreover, generation mechanisms of Tsunami damages are examined.

We examined values and applications of earthquake and tsunami stone monuments in Tokushima. The results of the study are as follows; (1) the purposes of stone utilization were to hand down records and lessons of earthquake and tsunami to posterity for its "presence", "conspicuousness" and "durability". (2) We recognized three cultural values of earthquake and tsunami stone monuments in Tokushima such as academic material, disaster prevention education material and disaster cultural asset. (3) We found that about 70% of earthquake and tsunami stone monuments in Tokushima have problems of their location and decipherment, and "teaching" function decreased remarkably. On the other hand, some stone monuments signs of their locations and/or explanations in modern Japanese were newly set up. (4) We collected the application cases of the earthquake and tsunami stone monuments in local municipals, areas and primary and junior high schools.
1 0 0 0 OA サブリーマン幾何からトロピカル幾何まで実代数幾何的綜合研究
サブリーマン幾何やトロピカル幾何と関連する外微分式系の積分曲線に付随する特異曲面に関して,実代数幾何の見地から特異性の分類を実行し,ジェネリックな標準形を完成させた.ルジャンドル双対性と制御理論の見地から,枠付き曲線や曲面の接線ヴァライティーの特異性を分類し,写像のオープニング構成の概念を発展させ,一般の部分多様体の接線ヴァライティーの特異性の分類問題に応用した.また,G2サブリーマン幾何を非線形制御理論と実代数群の表現論の側面などから研究し,関連する特異性を分類した.さらにD4幾何の三対性とD型特異点論を進展させた.以上について論文を執筆し,国際的学術雑誌に発表済みまたは現在投稿中である.
