M6。2004年10月23日17时56分，在新泻县王子谷市附近震中深度13公里处发生的新泻县中8级地震。地震引发了362处宽度超过50米的滑坡和12处体积超过100万立方米的大型滑坡（国土交通省2005）。日本文部科学省（文部科学省）组织了由文部科学省科学技术特别协调基金资助的2004年新泻县中部地震灾害调查队。调查包括四个主题，（1）地震灾害，（2）滑坡灾害，（3）地下结构灾害，（4）综合研究。主题二：滑坡灾害调查组（组长：Kyoji Sassa）由防灾研究所的科学家/工程师组成（京都大学）产业科学研究所（东京大学），雪区灾害研究所（新泻大学）、地理调查研究所、国立地球科学和灾害预防研究所、林业和森林产品研究所、国家农村工程研究所、公共工程研究所和国家火灾和灾害研究所。在本报告中，“主题2：滑坡灾害”课题组组长佐佐作了滑坡灾害概要的报告，日本气象厅的冈田贤二报告了地震前降雨的影响，新泻大学的丸井秀明报告了采取的应急措施。作为主题2的一部分，对特定方面进行的其他调查作为独立报告在本期Landslides中报告（Hirata et al. 2005; Konagai 2005; Nakasato and Konishi 2005; Sassa et al. 2005; Sato et al. 2005）。图1显示了由新潟县中部地震引发的部分滑坡的位置。
The M6. 8 Mid-Niigata Prefecture earthquake, occurred at an epicentral depth of 13 km near Ojiya city in Niigata Prefecture at 17: 56 on 23 October 2004. 362 landslides with widths of more than 50 m and 12 large-scale landslides with individual volumes of more than 1 million cubic meters were triggered by the earthquake (Ministry of Land, Infrastructure and Transport 2005). The Ministry of Education, Culture, Sports, Science and Technology (MEXT) of Japan organized the 2004 Mid-Niigata Prefecture Earthquake Disaster Investigation Team funded by the MEXT Special Coordinating Fund for Science and Technology. The investigation consisted of four themes,(1) earthquake disasters,(2) landslide disasters,(3) underground structure disasters, and (4) integrated research. Theme 2: Landslide Disaster Investigation Team (Team leader: Kyoji Sassa) consisted scientists/engineers from the Disaster Prevention Research Institute (Kyoto University), the Research Institute of Industry Science (University of Tokyo), the Research Institute for Hazards of Snowy areas (Niigata University), the Geographical Survey Research Institute, the National Research Institute for Earth Science and Disaster Prevention, the Forestry and Forest Products Institute, the National Institute for Rural Engineering, the Public Works Research Institute, and the National Research Institute of Fire and Disaster. In this report, the outline of landslide disasters is reported by Sassa as the team leader of Theme 2: Landslide disasters; and the influence of rainfall before the earthquake is reported by Kenji Okada of the Japan Meteorological Agency; and emergency measures undertaken are reported by Hideaki Marui of Niigata University. Other investigations on specified aspects conducted as a part of Theme 2 are reported as independent reports in this issue of Landslides (Hirata et al. 2005; Konagai 2005; Nakasato and Konishi 2005; Sassa et al. 2005; Sato et al. 2005). Locations of selected landslides triggered by the Mid-Niigata Prefecture earthquake are shown in Fig. 1.
