Swiss residents in shock after glacier debris buries village
WILER: Swiss residents were struggling on Thursday to absorb the scale of devastation caused by a huge chunk of glacier that has buried most of their picturesque 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 the mountain on Wednesday, engulfing some 90 percent 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 on Thursday 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 kilometers 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 neighboring village of Wiler. Nearby, the road ran along the valley before ending abruptly at the mass of mud and debris now blanketing her own 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 making preparations 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. 'The worst case scenario is possible flooding.' Up to one 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 some residents of neighboring villages had been evacuated as a precaution.
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 this week's collapse. 'Unexpected things happen at places that we have not seen for hundreds of years, most probably due to climate change,' he said. — Reuters

Pioneer spirit drives Swiss solar-powered plane altitude attempt
SION: Swiss pilot Raphael Domjan on Friday made his first attempt of the year at setting a new aviation record: reaching an altitude of 10,000 meters in a solar-powered aeroplane. The SolarStratos electric plane took off from Sion airport in the Rhone valley in southwestern Switzerland at 1:21pm, in the hope that conditions higher up would prove favorable for record-chasing. But it soon became clear that the rising warm air thermals Domjan needed to boost the ascent were not there, and it was better to save energy and try again another day—all in the pioneer spirit, according to the adventurer. The wildfires in neighboring France were likely among the reasons why the forecast conditions had changed. Domjan touched down 38 minutes later, deciding to preserve the charge in the batteries with a view to another go on Sunday or Wednesday, when the baking hot conditions look more promising. 'The flight was good but we didn't find any thermals,' he told AFP after opening the cockpit and taking off his helmet, sweat rolling down his cheeks. 'We really needed to find something to climb... the sun was there but not the thermal activities. 'It was clear that it would not work. We tried.' 10,000-metre challenge Domjan is aiming to get to 10,000 meters or beyond—flying at the same altitude as airliners. Such a flight would take at least five hours. 'It's more difficult than expected,' said the 53-year-old, who describes himself as an 'eco-explorer' committed to climate protection. 'That's why we are the first to go there,' he said, adding: 'We try because it's difficult.' A warm-up flight on July 31 got to 6,589 meters—the highest-ever for SolarStratos. The propeller plane, made of carbon fibre, is 9.6 meters long. It has a huge wingspan of 24.8 meters to accommodate the 22 square meters of high-spec solar panels topping the wings. The current altitude record for a solar plane stands at 9,235 meters, set in 2010 by the Solar Impulse experimental aeroplane, flown by Swiss pilot Andre Borschberg. 'We'll try and try until we go to 10,000 meters, or it's the winter when there is no sun and we cannot try anymore,' said Domjan. On Friday, Domjan reached 1,769 meters but quickly decided there was no point draining the batteries looking for thermal currents that were not going to show. The slow-charging plane will be parked back out in the sun to fill the batteries for next time. Hanging in the sky Domjan's mother was there to wave him off on his record attempt. After getting strapped into his emergency parachute and making a few last-minute notes on paper, Domjan strode towards his plane. 'Right, see you later,' he said before clambering into the cockpit. The hubbub in the hangar went quiet as he tested his oxygen mask, donned his helmet, checked his instruments and gave a farewell fist-bump before closing the canopy. The plane taxied on the runway to the gentle sound of a traditional Swiss alphorn, with Sion's Tourbillon Castle and Valere Basilica providing a striking backdrop. Almost immediately, SolarStratos was airborne, its slow movement giving it the impression of hanging in the sky as it drifted down the valley. The plane made several turns as it gradually climbed beyond the lower terraced vineyards, above the deep green pine trees, and then towards the snowless Alpine peaks piercing the clear blue sky. But Domjan found no rising thermals as he searched around Mont Gord—and it was better to turn back. In 2012, Domjan became the first person to sail around the world in a fully solar-powered boat. 'If you want to be a pioneer, when you start you will never know if you will be a pioneer of success or a pioneer of failure,' he said, once back in the hangar on Friday. 'To be a pioneer, an adventurer, it means trying something you are not sure will succeed. 'The pioneer spirit for me, the spirit of adventure is to try something that nobody has tried before, and maybe you will not be able to reach success.' - AFP

As a landslide threatens an Alpine village, Swiss authorities expand evacuation order
GENEVA, May 19, (AP): Swiss authorities on Monday expanded the evacuation of an Alpine village threatened by a possible landslide, ordering most of its people to leave. More than 90 people were evacuated on Saturday night from their homes in Blatten, in the Lötschental - a valley above the larger Rhone valley in the southern Valais canton (state). On Monday, authorities in Valais announced the complete evacuation of the village of some 300 people, with the exception of two areas, citing a risk of falling rocks and landslides. It wasn't immediately clear when residents would be able to return home. Local official Matthias Ebener told public broadcaster SRF that "the situation is very acute.' There have been repeated small rockfalls in the area. In 2023, residents of the village of Brienz in eastern Switzerland were evacuated before a huge mass of rock slid down a mountainside, stopping just short of the settlement. Brienz was evacuated again last year because of the threat of a further rockslide.
