China megaprojects face geological risk at Medog dam

Overview

China’s recent wave of megaprojects continues to confront serious geological challenges. The Motuo (Medog) hydro‑electric scheme on the Yarlung Tsangpo, slated to become the world’s largest at 60 GW and expected to generate about 300 TWh annually, began construction in 2025 near the Indian border.

A July geological study confirmed that the active Paizhen Fault runs directly beneath the dam site. The fault, active since the Pleistocene and linked to the 6.9‑magnitude 2017 Milin earthquake, has fractured surrounding rock, creating weakened foundations and elevating the risk of landslides, slope failures or even dam collapse under seismic loading or prolonged water immersion.

Researchers have urged stronger engineering responses, including extensive slope reinforcement and retaining barriers. The findings have revived concerns from India and Bangladesh over potential reductions in downstream Brahmaputra/Jamuna flows, adding a geopolitical dimension to the technical hazards.

Chinese officials maintain that comprehensive geological assessments have been carried out and that the project will meet safety and environmental standards, but the new data keep safety and cross‑border water‑resource issues under close scrutiny.
