Rescue Effort Narrows to Three Mud‑Choked Hydropower Tunnels as Nepal Toll Exceeds 1,350

Attempts to reach about 121 people believed trapped in tunnels are slowed by deep silt, damaged roads, overwhelmed forensic capacity, limited helicopter access

Overview

  • A sudden ice‑and‑rock avalanche on August 26 sent a debris flood down the Bhotekoshi and Trishuli corridors, killing more than 1,350 people and leaving roughly 4,900–5,400 missing across Nepal and Tibet.
  • Authorities now concentrate search teams on three tunnel sites — Chilime and Upper Trishuli 3A/3B — where the army says about 121 of the hydroelectric workers could still be trapped inside interconnected, mud‑filled tunnels.
  • Rescuers report heavy technical limits: excavators and equipment sink in thick sludge, narrow valleys block large helicopter lifts, and teams must use specialist tunnel methods and manual clearance to reach buried passages.
  • Mortuary and identification systems are overwhelmed, with only a small share of recovered bodies formally identified, prompting temporary burials and large DNA‑sample efforts that are slowing family notifications.
  • Nepal has accepted international help and is prioritising emergency bridge and road repairs to restore access, while families hold protests and pressure authorities for faster, clearer rescue and accountability.
