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 seriously damage by the Niigata-ken Chuetsu Earthquake in October 23, 2004, was occurred in the south-eastern area of Nagaoka City, which was distant about 10km from its epicenter. Many wooden buildings and dozohs (mud-walled buildings) were transformed, and collapsed, but damage to reinforced concrete building was slight. The damage to wooden buildings was focusing on the range of 80-100m width, extending toward the northeast-southwest, which is identical with the boundary of alluvial plain and more higher plain. 続きを見る
