A post GLOF look at parts of Teesta Valley (Part - 2)

More than a year has passed since the devastating GLOF disaster of October 4, 2023, that swept through the Teesta Valley. We have extensively documented the catastrophe and its aftermath in this blog. Following the GLOF, the 2024 monsoon season brought further destruction, exacerbating the damage to already weakened structures, roads, and the environment.

In the photos below, we aim to capture the changes that have unfolded during this time. With another monsoon fast approaching, our repeated calls for mitigation efforts during this dry, non-monsoon period have largely gone unheeded except for the transfer of maintenance of sections of NH10 in West Bengal from the state PWD to NHIDCL, a step forward, which is widely regarded as too little, too late.

Both these bridges on the river bed and a larger bridge which spanned the river were swept away during the monsoons of 2024.

Chungthang: satellite images of BEFORE and AFTER the Glacial Lake Outburst Flood (GLOF) of 04Oct2023


STH has covered the Glacial Lake Outburst Flood (GLOF) from South Lhonak Glacier extensively in this blog with stories, many images and maps of the devastation which followed all along the Teesta River Valley.
The GLOF hit Chungthang town at around 12.35am on 04Oct2023 causing loss of life and livelihoods and tremendous damage to infrastructure.
Placed above are comparative satellite images of BEFORE the GLOF (Google Earth) and AFTER the floods (NRSC)
The scale of devastation is at once visible - with large swathes of Chungthang town totally covered with debris/sand and the humongous (1200MW) Stage III Sikkim Urja dam destroyed, in the NRSC image of 13Oct2023.
