Many geotechnical disasters, such as slope failure and liquefaction, occurred in the Niigataken Chuetsu-oki Earthquake in 2007. Most of these damages concentrate on geological boundary such as the foot of sandy dune. In order to delineate geological structure in the disaster area, a series of investigations was carried out. The surface-wave method was carried out firstly. Next borings and soundings were conducted at the selected points based on the Swave velocity model obtained from the surface-wave method. Investigation results clearly showed the efficiency of the investigation method by combining the surface-wave method with the following detailed investigation such as the borings and soundings.
