Massive landslide blocks major rivers in Sikkim, officials assess damage

A massive landslide has swept down the slopes of the Eastern Himalayas in Sikkim, creating a natural dam that has choked the flow of multiple rivers in the region. The sudden blockage has raised concerns about rising water levels upstream and reduced water supply downstream, affecting villages that rely on these rivers for irrigation and drinking water.
State disaster management officials arrived at the site within hours and are coordinating with the National Disaster Response Force to evaluate the stability of the landslide mass. Engineers are deploying remote sensing equipment to monitor any further movement and to gauge the risk of a potential breach that could trigger flash floods.
Local residents have been evacuated from low‑lying areas as a precaution, and relief camps have been set up in nearby towns. The administration has also warned commuters about possible disruptions to road and rail links that run alongside the affected river valleys.
Authorities are urging the public to stay clear of the danger zone and to follow instructions from emergency services while a comprehensive rescue and mitigation plan is being formulated.
