After two major earthquakes in Niigata Prefecture, bump, which occurred mostly near the abutments in fine sand due to faulting. In this paper, the authors investigated mechanism of faulting with soil testing from the point of view of liquefaction in case of the 2007 Niigata-Ken Chuetsu-Oki Earthquake. We analyzed mechanism of land-fill by using the wave propagation based on real-time strong ground motion as to Chuetsu-Oki and Kaihoku for the mitigation in the Tokyo metropolitan area. As a result, it was confirmed that the bump can be reduced to level of approximately 1/10 by proper construction.
