NEW DELHI — A piece of a glacier broke off high in the Himalayas on Sunday, causing a deadly flash flood that smashed through a hydroelectric power plant and destroyed homes in India. More than 125 people were reported missing.
Ashok Kumar, Uttarakhand’s police chief, said the avalanche occurred at 11 a.m. Authorities evacuated several villages downstream.
Television channels aired footage of water barreling down a narrow canyon and sweeping away the power plant at its base. A second state-run power plant nearby also suffered extensive damage.
Most of the missing were workers at the two power plants. Troops dug a ditch to rescue about a dozen workers trapped in a tunnel. Videos of the operation showed rescue workers pulling out a man, who flung his arms in the air victoriously. Rescue operations continued the next morning at another tunnel, where an estimated 30 people remain trapped. Vivek Kumar Pandey, a spokesperson for the Indo-Tibetan Border Police overseeing the rescue said 300 men were on the job. “There is a huge amount of debris and slush in front of the tunnel. We are using earthmovers and excavators to remove it,” he said.
Girish Joshi, a consultant with the state’s disaster management authority, said that an eight-mile stretch of the valley was affected but that there was no further danger. “The river levels are normal now,” he said of the Dhauliganga and Alaknanda rivers. Joshi said there is “minimal chance” of those missing being found.
Authorities in the neighboring state of Uttar Pradesh said they were on alert and monitoring water levels.

Uttarakhand suffered a devastating flood in 2013 that claimed thousands of lives. Analysts have blamed climate change and unchecked construction for such disasters.
“This looks very much like a climate change event,” said Anjal Prakash, a professor at the Indian School of Business in Hyderabad. “The glaciers are melting due to global warming.”
Prakash, who serves on a United Nations panel on climate change, said that the Himalayan area is one of the least monitored in the region and that the disaster Sunday shows how vulnerable it can be.
Farooq Azam, a specialist in glaciology and hydrology at the Indian Institute of Technology in Indore, said glacial bursts are rare. He said more information is needed to understand the Sunday event, but “climate change-driven erratic weather patterns” such as increased snowfall and rainfall and warmer winters have led to the melting of “a lot of snow.”
Trivendra Singh Rawat, the chief minister of Uttarakhand, said that experts will look into the cause of the disaster but that the priority is to “save lives.” Prime Minister Narendra Modi said the nation “prays for everyone’s safety.”
