2016 , and also surges which were frequently found in this vast region , threatening the security of the local and down streaming societies .The total amount and area of glacier lakes increased during last decade  . Himalayan rivers are frequently hit by catastrophic floods caused by the failure of glacial lakes . In Kedarnath, India , a flash flood was triggered by glacier lake outburst flood  released from the Chorabari glacial lake in June 2013 which caused extensive flooding, erosion of riverbanks and damage to downstream villages and towns, as well as the loss of several thousand lives . Nepal has experienced 24 GLOF events which have caused considerable loss of life and damage to property and infrastructure . There is high confidence that current glacier shrinkages have caused more glacial lakes to form in most mountainous regions, including HMA, but there is limited evidence that the frequency of GLOF has changed . Veh et al.  reported no clear trend of increasing GLOF events in the Himalayan region, although the southern Himalaya was identified as a hotspot region compared with the western Himalaya. Research has shown a decrease in glacier area of 24% in Nepal between 1980 and 2010 .
