The incident occurred on Thursday evening inside the Tail Race Tunnel (TRT) of the under-construction Vishnugad-Pipalkoti Hydroelectric Project on the Alaknanda River. The workers were reportedly engaged in welding reinforcement bars when the landslide caused a large quantity of debris and water to enter the tunnel, trapping several workers inside.

Another worker has been referred to a higher medical facility for further treatment. The search for the remaining three workers trapped inside the tunnel is continuing.
