Glacier Collapse Floods Tibet and Nepal, Raising Questions About China
A large piece of ice reportedly broke away near Langtang Lirung in the Himalayas.
It fell more than two kilometres and caused powerful floods.
The floods affected villages in Tibet and Nepal.
The falling ice shook the ground like a magnitude-5.2 earthquake.
A report said Chinese authorities did not openly share information about the disaster in Tibet.
That could make it harder for people to receive warnings or find missing family members.
The report also said Himalayan glaciers are being affected by warming temperatures.
Rivers crossing borders can carry flood dangers from one country to another.
The article presented the disaster as both an environmental emergency and a political controversy.
A glacier collapse near Langtang Lirung reportedly triggered flash floods across villages in Tibet and Nepal.
The ice avalanche released seismic energy equivalent to a magnitude-5.2 earthquake, according to the report.
Khedroob Thondup accused Chinese authorities of suppressing information about the disaster inside Tibet.
The report said the lack of communication hindered warnings, relief coordination and information about missing relatives.
It linked the event to rising Himalayan temperatures, glacier instability and concerns about cross-border risks.
