Deadly Sikkim GLOF: a disaster foretold
At least 14 people were killed and over 100 are missing after South Lhonak glacial lake in the Indian state of Sikkim burst due to incessant rains, inundating downstream areas. The sudden deluge on the Teesta River destroyed the Chungthang dam and flooded several districts. Many residents remain cut off. Scientists had long warned that South Lhonak lake would burst. A detailed study, Future Glacial Lake Outburst Flood (GLOF) hazard of the South Lhonak Lake, Sikkim Himalaya, was published in Geomorphology journal in September 2021. It noted that the lake had witnessed a significant increase in size over the past decades due to glacial retreat. India’s Central Water Commission had initiated an advisory to evaluate the condition of the Himalayan lake system in Sikkim. (Photo via DownToEarth)
