We developed the following new technologies to improve the total risk evaluation involved in the slope failure due to torrential rain and earthquake(1) slope failure analysis support system containing latest geospatial information databases(2) advanced prediction scheme for strong earthquake motion(3) field survey for the effect of soil water contents on slope failure and debris flow run-out area(4) slope failure and debris flow simulator using particle method(5) fragility function of slope failure, and(6)risk analysis scheme of road damage due to slope failure.
