Active Fault Found Under China's Brahmaputra Dam Project
Scientists in China found an active fault under a huge dam project on the Brahmaputra River.
This dam, called the Medog Hydropower Project, is very big and expensive.
China says it's safe, but other countries are worried.
They think the dam could cause problems like earthquakes and affect the river's water.
China hasn't shared much information about how they plan to handle these risks.
The dam is important for China's energy needs, but it's also a big change to a very important river in Asia.
An active tectonic fault, the Paizhen Fault, runs beneath China's Medog hydropower project on the Brahmaputra River.
The project is estimated to cost USD 137 billion and is located near the Indian border.
Chinese researchers have raised concerns about the geological stability of the project due to the active fault and loose rock formations.
China maintains that the project is scientifically planned and poses no significant downstream risks.
Downstream countries are concerned about the lack of comprehensive water-sharing and basin management frameworks.
