Debris flow disasters are widely distributed in high-elevation or high-latitude mountain areas (referred to as debris flow in high mountains, DFHM), especially in areas where mountain glaciers and permafrost have receded rapidly. In the context of global climate change (temperature rising and higher possibility of occurrence of strong precipitation events), the actual hazards and potential risks of DFHM have drawn increasing attention. Unlike debris flows developing in low elevation environments which are mainly triggered by precipitation, the outbreak of DFHM is also significantly affected by temperature conditions, making its formation mechanism more complicated. Although a lot of research has been carried out on DFHM at home and abroad, effective prediction and early warning and prevention and control are still very difficult. It is of great scientific value and practical significance to further strengthen the starting conditions and mechanisms of glacial debris flow. This review summarizes the recent progress on initiation study of glacial debris flow, including: the relationship between glacial debris flow outbreak and meteorological conditions, causes of typical DFHM outbreaks, failure mechanisms and models of glacier (rock, or moraine deposits), and characteristics of moraine initiation. In the future, we should strengthen the acquisition of high spatial-temporal resolution meteorological data and the analysis and judgment of dynamic changes of material sources, and further clarify the formation conditions and development process of debris flow in alpine areas from the perspective of dynamic mechanism.

Key words: debris flows in high mountains, outbreak causes, mechanism of stability failure, initiation characteristics, hydrothermal conditions
