| Abstract: | Due to a continual rainfall, a flowslide occurred in Yamashina area, Kanazawa City, Japan on November 8, 2002 in the Tertiary
mudstone area. The sliding mass was fully fluidized during the motion and moved downward the slope for a long distance. On
December 31, 2003, slope failure was triggered by intensive rainfall and snowmelt water at the same site again, and resulted
in the second occurrence of flowslide. The total displacement of the slope was recorded with an extensometer. Through field
investigation, the difference of the sliding mechanism between the two flowslides was examined. |
