Since the last glacial age, climate warming led to the drastic changes in glacier environment in the global mountain areas, and the decrease of the stability of the Moraine Lakes leads to the increase of outburst frequency, which has become one of the frequent glacial disasters in more than 10 countries and regions all over world included China, Nepal, Russia, Peru and etc. Flood and debris flow induced by moraine lake outburst, due to its large scale, fast forming and wide spread, cause heavy losses of infrastructure, life and property in the downstream area. Through the summarization and analysis on the research situation and development status of Moraine Lake outburst flood events, outburst causes, outburst patterns and features of GLOF, this paper provides reference for the research and evaluation of moraine lake outburst.
