Residents in shock after glacier destroys Swiss village

Residents were struggling to absorb the scale of devastation caused by a huge chunk of glacier that buried most of their picturesque Swiss village, in what scientists suspect is a dramatic example of the impact of climate change on the Alps.
A deluge of ice, mud and rock crashed down a mountain yesterday, engulfing some 90% of the village of Blatten. Its 300 residents had already been evacuated earlier in May after part of the mountain behind the Birch Glacier began to crumble.
However, rescue teams with search dogs were still scouring the area today for a missing 64-year-old man after an initial scan with thermal drones found nothing.
As the Swiss army closely monitored the situation, some experts warned of the risks of flooding as vast mounds of debris almost two kilometres across are clogging the path of the River Lonza, causing a huge lake to swell amid the wreckage.
"I don't want to talk just now. I lost everything yesterday. I hope you understand," said one middle-aged woman from Blatten, declining to give her name as she sat alone disconsolately in front of a church in the neighbouring village of Wiler.
Nearby, the road ran along the valley before ending abruptly at the mass of mud and debris now blanketing the village. Just a few roofs poked up through the sea of sludge.
A thin cloud of dust hung in the air over the Kleines Nesthorn Mountain where the rockslide occurred while a helicopter buzzed overhead.
Martin Henzen, another Blatten resident, said he was still trying to process what had occurred and did not want to speak for others in the village, saying only, "Most are calm, but they're obviously affected."
They had been preparing for some kind of natural disaster but "not for this scenario," he added, referring to the scale of destruction.
'Enormous plug'
But the immediate dangers might not be over.
"The water from the River Lonza cannot flow down the valley because there is an enormous plug," Raphael Mayoraz, a cantonal geologist, told Swiss national broadcaster SRF, saying floods in downstream villages were a possibility.
Up to 1 million cubic meters of water are accumulating daily as a result of the debris damming up the river, said Christian Huggel, a professor of environment and climate at the University of Zurich.
Matthias Ebener, a spokesperson for local authorities, said that buildings which had emerged intact from the landslide are now flooded and that some residents of neighbouring villages had been evacuated as a precaution.
The army said in a statement that water pumps, diggers and other heavy equipment are on standby to provide relief when it is safe.
Authorities were airlifting livestock out of the area today said Jonas Jeitziner, a local official from neighbouring Wiler, as a few sheep scrambled out of a container lowered from a helicopter.
Asked how he felt about the future, he said, gazing at the debris, "Right now, the shock is so profound that one can't think about it yet."
The incident has revived concern about the impact of rising temperatures on Alpine permafrost which has long frozen gravel and boulders in place, creating new mountain hazards.
For years, the Birch Glacier has been creeping down the mountainside, pressured by shifting debris near the summit.
Matthias Huss, head of the Glacier Monitoring in Switzerland (GLAMOS), pointed to the likely influence of climate change in loosening the rock mass in the permafrost zone, which triggered the collapse.
"Unexpected things happen at places that we have not seen for hundreds of years, most probably due to climate change," he told Reuters.
