Chinese geologists question safety of Brahmaputra Mega-Dam in Tibet being built over active seismic fault line
This article addresses a critical transboundary river issue with direct implications for India-China relations, Himalayan seismicity, and disaster management. Prelims can test factual details: cost, location, energy output, and the Paizhen Fault. Mains may explore impacts on India's water security, environmental risks, and geopolitical tensions. UPSC syllabus covers international relations, geography (Himalayan tectonics), and disaster management. State-specific exams like APSC will focus on downstream effects on Assam and Arunachal Pradesh.
- Chinese geologists have found an active fault line (Paizhen Fault) beneath the world’s largest hydropower project on the Brahmaputra River in Tibet, raising structural stability concerns.
- The $167.8-billion dam, officially under construction since July 2024, is expected to generate over 300 billion kWh annually, meeting the power needs of more than 300 million people.
- The dam site is located near the Indian border in Arunachal Pradesh, within the Himalayan seismic belt, and the researchers cited the 2017 Milin earthquake (magnitude 6.9) as evidence of ongoing seismic activity.
