Imja Glacier |
The Global Warming is causing the Glaciers to melt fast and ultimately it will cause Glacier to explode causing damage of life and property in large scale.The major six Glaciers facing dangers are:
1. Thulagi glacial
lake in Manang
2. Cho-Rolpa
3. Imja
4.Lumding
5. Lower Barun
6.Western Chamjang
According to this recent
study conducted in the mountainous regions, temperature in the region was
increasing at a rate of 0.09 degree Celsius every year and this was posing
threat to glaciers.The Thulagi lake is situated 2500-meter long,
500-meter wide and 80-meter deep.According to the report published by
International Centre for Integrated Mountain Development (ICIMOD)
the Thulagi lake is getting 22m meter narrower every year.If
the lake is exploded the property worth of billions will be destroyed
and it will claim a life of thousands.This will also
hit hydro power projects in the Marsyangdi watershed area, the report
says.If the lake gets burst, it will hit Manang, Gorkha, Lamjung and
Tanahu districts hard. Similarly, Kaski, Syangja, Baglung, Myagdi, Mustang and
Parbat will also be affected.
How Glacier is Formed?
Glacial lakes form when a glacier retreats leaving the debris mass at the end of the glacier – the end moraine – exposed. The moraine wall can act as a natural dam, trapping the melt water from the glacier and leading to the formation of a lake. The moraine dams are composed of unconsolidated boulders, gravel, sand, and silt. As with landslide dams, they can eventually break catastrophically, leading to a glacial lake outburst flood or GLOF. GLOFs have the potential to cause extensive destruction in the downstream valley.
