Abstract: A big powder avalanche occurred at 23:00 on January 26, 2986 at Maseguchi, Niigata prefecture in Japan. Thirteen people were killed, eleven people injured, eight houses crushed and three houses partially destroyed by this avalanche. The avalanche occurred on the east slope of Mt. Gongen (1,108 ma.s.l.). The relative height of Mt. Gongen to Maseguchi Village was 800 m. and horizontal distance between them was 2000 m. The location of Maseguchi Village, Nou Town, Niigata Prefecture is shown in Fig. 1, and the profiles of the avalanche track and slope are shown in Fig. 2. The angles of a steep mountain slope and a gentle mountain foot were 45 degrees and 12 degrees respectively. At once we organized a research party as shown in Table 1, and it was supported by the Grant-in-Aid for Cooperation Research and Science Research of the Ministry of Education, Science, and Culture, Japan, and we published a report including 14 papers written by Japanese at the end of March, 1986 (Kobayashi et. al., 1986).
