China’s proposal to construct the world’s largest dam on the Brahmaputra River near Arunachal Pradesh has been halted after a geological survey revealed an Ice Age fault zone that could pose significant risks.
China has long aimed to build the world’s largest dam on the Brahmaputra River, a project that would span the border region near Arunachal Pradesh. The proposal, which has attracted international attention for its scale, was recently put on hold after a detailed geological survey identified an Ice Age fault zone in the area.
The fault, dating back to the last glacial period, could potentially trigger seismic activity or landslides if a massive structure were erected nearby. Experts warn that such a fault line could compromise the stability of a dam of this magnitude, raising safety concerns for both China and India.
Indian authorities have expressed apprehension over the project, citing the strategic importance of the Brahmaputra basin and the potential environmental impact. While China continues to pursue hydroelectric development along the river, the discovery of the fault has forced a reassessment of the feasibility and timeline of the dam.
The halt underscores the complex interplay between large-scale infrastructure ambitions and geological realities in the Himalayan region. Both nations are now expected to engage in further studies before any definitive decision is made.
The situation remains fluid, with stakeholders monitoring the outcome of subsequent geological assessments and diplomatic negotiations.
