概要: The Niigata Chuetsu earthquake (M6.8) occurred on October 23, 2004. It caused widespread hazards and damages in the Chuetsu area, Niigata Prefecture, which including 46 deaths, house destruction of more than 100,000, a great deal of land deformation and structures. Especially, a seismometer installed in the Kawaguchi Town, where located in the eastern part of the epicenter, recorded seismic intensity of 7. We investigated the earthquake hazards and property damages in the Wanazu district, Kawaguchi Town, and preliminary examined the geomorphological and geological aspects of land on which the houses are situated. Most of properties in this district are situated on four terrace surfaces, flood plain, natural levee and two alluvial fans. The house damages are concentrated on steep slopes of alluvial fans overlying terrace and gently slopes of alluvial fan deposits, and are also comparatively concentrated on terraces in the left bank of the Uono River. On the other hand, the house damages situated on terraces in the right bank of the Uono River are less than on which in the left one. Therefore, it is inferred that ground in the Wanazu district were received strong motion by the Niigata Chuetsu earthquake on the left bank of the Uono River. 続きを見る

概要: The central city area of Nakanoshima Town, Niigata Prefecture was flooded by the rapid levee breach of the Kariyata River on 13 July 2004, which caused damages to many houses. Main flood streams flowed into the central city area, and changed the flow pass westward (clockwise) due to the presence of natural levee high. House damages of the central city area were concentrated approximately 250m around the point of levee breach. The damages were conspicuously occurred in vacant lots and/or streets which became passes of the flows with a hydraulic bore. Locality, house damages were reduced probably by rubbish and grove belts that contributed to reduction of the flow energy. Some house damages were observed 400m from the levee breach that may be caused by a reconcentration of streams. 続きを見る

概要: Niigata-ken Chuetsu earthquake (M6.8) was occurred in the Chuetsu district in Niigata Prefecture at 17:56 23rd October, 2004. Damage becomes the large disaster of fatalities 46 persons, serious or slight injury person 4,791 persons, complete collapsed house 2,827, half collapsed house 12,746, partly failure house 100,453 at 18th March. Serious damages such as Kawaguchi Town and Ojiya City, which recorded seismic intensity of 7, are unevenly distributed. The localization of this damage seemed to appear by many factors such as strong motion, surface geology, structure and actual age of the houses etc. ln this study, distribution of building damage and subsurface deformation were mapped out in the western part of the Uonuma City (ex-Horinouchi Town) at the eastern part of the hypocenter. From the distribution of the completely collapsed house, the concentration of the damage of the western part of the Shin-Doujima were caused by the strong motion from the hypocenter. In the future, ground and geological structure will be examined from field investigations, seismic prospecting, etc. 続きを見る

概要: A tragic flood disaster was occurred by the unprecedented heavy rainfall around the Chuetsu area of Niigata Prefecture on July 13, 2004. The levees of the Ikarashi-, Kariyata-, and Chigoshimizu Rivers were broken in many places, and the many houses, then, were swept away and the wide area was under muddy flood water in Sanjo and Mitsuke Cities and Nakanoshima Town. The writers made the survey of this disaster and report on the situation of damage of houses, the area and depth of the flood, the scouring and orientation of flood current, and the relation of the damaged area to the geographical condition in this paper. 続きを見る

概要: The Niigata Chuetsu earthquake occurred on October 23, 2004 (magnitude 6.8), caused severe hazards and extensive damages in the Chuetu area, Niigata Prefecture. This region is characterized by agricultural lands and hence, there is little variation of buildings and houses. Many Japanese style wooden houses were severely damaged. We investigated the damage of Japanese wooden houses and structures in the Tamugiyama district, Kawaguchi Town. Initially we examined the geomorphological and geological aspects of the land on which the houses are situated. Most of the houses and buildings in the district are situated on poor-sort admixture consisting of sand and mud gravel beds that has low resistance to ground motion. The house damages are concentrated in the east of the district probably due to the intensive spread of strong motion and earthquake energy. Also, the damages are obvious on the edges of terrace surfaces and on steep slopes of small-scale alluvial fans (taluses) accompanied with rupture of ground surfaces. 続きを見る
