“With climate change causing the rapid melting of glaciers, the glacial lakes are growing so quickly that the risk of a disaster occurring throughout the Himalayas is increasing,” said Pradeep Mool, of the International Centre for Integrated Mountain Development (ICIMOD), a Kathmandu-based organization funded by eight countries that researches climate change and mountain ecosystems.
“GLOFs come very fast, carry great big boulders; they can push down rock walls and destroy river banks. The destructive impact is very, very high,” Mool told IRIN by phone from Kathmandu.
GLOFs occur when the natural dams of ice or rock containing glacial lakes collapse because the lake has rapidly increased in size or its walls are shattered by earthquakes or avalanches. The resulting floods can cause rivers downstream to rise up to 35 metres, destroying everything in their path for up to 100km in only eight hours, he added….
