Characterisation of Slope Failures During the 2004 Niigata-Ken Chuetsu and the 2007 Niigata-Ken Chuetsu-Oki Earthquake
Abstract eng: Slope failures mainly occurred in costal terraces during the 2007 Niigata-ken Chuetsu-oki Earthquake because the earthquake centre was on coastal region in the north of Kashiwazaki City and Kariwa Village. On the other hand, hilly and mountainous areas suffered heavy damage from the 2004 Niigata-ken Chuetsu Earthquake although the distance of epicentre between those two earthquakes was only about 40 km. Topographical and geological characteristics of Chuetsu area were discussed comparing the damaged areas of both earthquakes in the paper. Typical slope failures during the Chuetsu-oki Earthquake including liquefaction in sand dune were reported in detail. In addition, soil samples were obtained from the sites of the slope failures in both earthquakes. Using the samples, physical and shear tests were conducted to elucidate the soils' strength properties.
