The National Disaster Management Authority is surveying the Eastern Himalayas to map all glacial lakes in the country.
As a part of the national survey to preempt the Glacial Lake Outburst Flood (GLOF), the National Disaster Management Authority (NDMA) has started surveying the Eastern Himalayas to map all glacial lakes in the country and assess the feasibility of installing early warning sensors and other mitigation measures. The agency is conducting surveys in Arunachal Pradesh and Sikkim, the two important areas of the Eastern Himalayas along the China border.
Expert teams have fanned out to carry out a survey-cum-study at six high-risk glacial lakes in Tawang and Dibang Valley districts in Arunachal Pradesh, which shares a 1,080 km-long border with China. There are reports of the washing away of more than five bridges due to a glacial lake outburst from Sangnga Nehgu Lake in the Tawang district. It is also the first such survey of glacial lakes in the border state.
Sikkim has also sent an expedition of 32 experts to five under-threat glacial lakes - Gurudongmar A, B, and C, Sakho Chu, and Khangchu, all in the Mangan district, which borders Tibet.
