Abstract: Recently, many sCIentists have developed a technique for predicting maximum avalanche run-out distance (Lied and Bakkehoi, 1980; Bakkehoi et al., 1983; Martinelli, 1986; McClung and Lied, 1987). The objective of this study also is to know the run-out distance of a long-running avalanche which caused heavy damage in Japan. The relations among the total volume (V) of snow broken in a rupture zone, the vertical avalanche fall height (H), the total horizontal distance (L) and the altitude (h) of the start point of the avalanche were investigated using the records of recent avalanche disasters which occurred in Japan, including several big scale avalanches.
