| Outline of Final Research Achievements |
Throughout Japan, large scale residential development on hillsides accompanied by massive grading operations in the suburbs of large cities started in the 1960s. However, the performance of landslide during strong motion has not been discussed based on observed facts. Thus, both earthquake ground motion and pore water pressure observations in the urban slopes including valley fill slopes were conducted in the southwestern Tokyo and the central part of Yokohama city.Notable amplification of seismic response at the edge of terrace and on the valley fill slope, and the characteristic motion of valley fill controlled by valley shape were clearly observed during strong earthquake.These basic information will be valuable for discussing on prediction of valley fills type landslides induced by strong seismic motion in urban region. Precise field observation on landslide movement during earthquake should be significant to mitigate the landslide risk in urban region.
