Sources said Leh had witnessed Glacier Lake Outburst Flood (GLOF) in 1833, 1834, 1841, 1858, 1930 (Shayok Valley); 1907 and 1908 (Leh), 2003 (Domkhar), 2010 (Nidder), 2014 (Gaya), 2015 (Phugtal) and 2017 (Achinathang) etc as due to climate change the glaciers are thinning and retreating resulting into formation of glacier lakes on mountain peaks.
“As Glaciers retreat, the formation of glacial lakes takes place behind moraine or ice dam. These damming materials are generally weak and can burst suddenly due to various triggering factors like formation of lake in weak morain structures leading to floods,” they added.
