Nepal rescue efforts stalls as relentless rain fuels fresh fears

China has constructed dozens of underground hydropower projects near Nepal's Rasuwagadhi Valley adjoining Tibet, including operational projects along the Yarlung Tsangpo River and the planned Midog Dam.

Analysts express serious concerns regarding the environmental and seismic implications of this unprecedented construction in a fragile, environmentally unpredictable region.

Massive underground tunneling and interconnected hydropower projects are suspected to have played a role in recent disasters.

With China warning that future disasters could be five times stronger, concerns grow over the ecological impact downstream reaching the shores of India.
