Other AbstractTwo large debris flows caused by ice-snow meltwater and rainfall have occurred on both southern and northern sides of the ice tongue of Hailuogou Glacier in the distance of 5 km from the large icefall at an elevation of 3 720 m on the eastern slope of Mt. Gongga since 1976.In front of the glacier tongue, a fan with about 5.5 × 104m3 material formed by two ice-snow meltwater and rainfall debris flows occurred on the 8th and 26th of July, 1989, in the Guanjingtaixigou. The debris flows carried the superglacial till away, broke the ice-body, cut a ditch with 1.2 km long on the northern side of the Hailuogou Gl., and also made the subglacial river change the way.In Aug., 1976, two sliding debris flows occurred at the moraine fringes, more than 200 m in the relative height, of No. 3 Glacier of Changcaoba, southern side of Hailuogou Gl.. Their occurrence results from the buried ice melted, ice-snow meltwater, rainfall and earthquake etc.According to the influence factors of climate warming, glacier retreating, ice-body thinning, frequent avalanche occurring, melt till increasing, buried ice melting, steep and high moraine unstabilizing, fluid precipitation increasing and earthquake affecting, authors declare that the larger scale of ice-snow meltwater and rainfall debris flow may occur again in the ice tongue sector of Hailuogou Glacier from now on. This will have influence on the action of tourism, climbing and scientific exploration etc. in some degree in the rainy season (June to Aug.) of every year, people should keep vigilant over occurrence of a large calamity.
