| Abstract;In 2004, Niigataken-Chuetsu Earthquake occurred and gave serious damages around Nagaoka City, Ojiya and Yamakoshi Village. Many geotechnical disasters, such as collapse and landslide occurred caused by the earthquake around these areas. In these areas, late Miocene to Pleistocene sediment were covered and made up of strongly folded. In this study, the investigated results are discussed with emphasis on the relations between the earthquake geotechnical damages in terms of slope failure, landslide and geological factors. The present study shows that the earthquake induced slope collapses are concentrated in the areas with slope and volcanic tuff distribution. (author abst.) |
