Alluvial fans and cones on the foot of volcanoes have high hazard potential because of frequent inundation of debris flows and floods accompanying marked topographic changes. However, the social needs for the development of such lands are ever increasing, because of their high demand for recreational sites. Assessment of hazard potential and regulation of land use are thus urgent problems. This paper proposes fundamental principles for the assessment of hazard potential on the basis of a case study carried out at the Kikkakezawa Fan on the southern foot of Mt. Yatsugatake, central Japan . History of land use is summarized in Fig. 3. Existing villages are located below a major spring zone in the alluvial fan, which is fed by the groundwater in the volcanic body. Construction of a new road (PR) stimulated land developments along it and further upstream part of the fan. According to Kosaka (1992) the debris-flow deposits cover the fan in three geologically distinct ages (Fig.5). The ages of the deposition of the debris flows in the new and middle ages are estimated according to a close examination of aerial photographs (Fig.6) and a reconnaissance study of the microtopography (Fig.7). It then enables an estimation of the frequency of the debris flow inundation in the future. The site-by-site assessment of hazard potential and risk of disasters is usually difficult because the past occurrences of inundation are not always recorded and a reliable estimation of its future possibility is hardly available. It is, therefore, essential to regulate land use for individual areas on the basis of the assessment of the hazard potential from the regional viewpoint using the data about the geomorphic processes of a large time scale. In Fig.3,for example, it is obvious that the areas above the prefectural road (PR) constitute a zone of high hazard potential and high risk, among which the area of the planned extension of the golf courses (Gp) are extremely dangerous.

唐の実又難陀訳「華嚴經」80巻のうちの巻19、20を合冊したもの。料紙は黄檗染紙、界線は淡い朱線。界高23.3cm、界幅1.9cm、毎行17字。巻頭表題下方に、千字文帙号とみられる「章」字、紙数、「大和寧国蔵」字を記す。字様は勤直、墨色は漆黒。幅広の折帖に仕立て、板表紙を付して、それに隷書で「華嚴經第十冊」と刻し、緑青を入れてある。後代の改装とみられる。この一類は国内外10か所余の所蔵が知られる。書写時期・地点については諸説ある。奈良時代、唐・宋・元代、渤海、さらに明初にモンゴル族オイラートの建てた大和寧国説など。最近の研究では、料紙・朱界線・書風など、北宋代の写本大蔵経の特徴と共通点が多いとされている。
