Satellite images show Swiss village wiped out by glacier collapse
New terrifying satellite images have revealed how a tiny Swiss village was completely wiped out by a massive glacier collapse. The remote Alpine village of Blatten was flattened after an avalanche of rock, mud and ice was sent crashing down into the valley. Once home to around 300 people, it now lies buried beneath a vast expanse of debris after the Birch Glacier broke off on Wednesday afternoon. Authorities say 90 per cent of the village has been destroyed. New satellite pictures reveal the true scale of the disaster, showing where homes, farmland and roads once stood, now completely smothered by mud and rubble. The river Lonza, which runs through the valley, has been blocked by the landslide, which had raised fears of further flooding. But as reconnaissance flights and inspections continued, authorities said water from the newly formed lake, which has been slowly submerging the remaining houses in the obliterated village of Blatten, was beginning to find its way over, through and around the blockage. 'This development is positive, but we remain cautious,' said Stephane Ganzer, head of the regional security department. 'The risk remains, even if it is diminishing,' he told a press conference, adding that 'no evacuations are planned' in the villages downstream in the Lötschental valley, one of the most picturesque regions in southern Switzerland. The outflow "makes us optimistic and suggests that the water is finding a good path", explained Christian Studer of the Wallis canton's Natural Hazards Service. However, work to pump water from the lake has still not begun as the ground remains too unstable, particularly on the mountainside. One 64-year-old man is still missing. He was believed to be in the area at the time. Switzerland's president has pledged support for those forced to flee the Alpine village of Blatten, telling evacuees they are 'not alone' after a devastating glacier-triggered landslide wiped out homes and businesses. Karin Keller-Sutter made the comments on Friday after surveying the destruction by helicopter. She said the government was now working to calculate ways to help those affected by the disaster. 'The force with which the mountain here wiped out an entire village is indescribable,' said Keller-Sutter. 'I'd like to tell you all that you're not alone. The whole of Switzerland is with you — and not just (people) in Switzerland.' Officials have limited access to the area and warned that huge deposits of debris, stacked tens of metres high across a 2-kilometre stretch of the valley, have blocked the Lonza River and formed a new lake. The future course of the water remains uncertain. 'Unfortunately, the danger has not yet been averted,' Keller-Sutter added. Separate drone footage shown by national broadcaster SRF showed a vast plain of mud and soil completely covering part of the village and the river running through it. At around 3:30pm local time, a huge chunk of the Birch glacier broke off, according to emergency services in the Wallis region. Local police said the missing 64-year-old man was a local resident who was in the area at the time of the incident. A search and rescue operation was launched, with three specialists airlifted to the scene, while a drone with a thermal imaging camera was also used. 'Despite significant efforts, the man has still not been found,' police said. The village, including residents and a herd of 52 cows, had mostly been evacuated this week amid fears the 52mn cubic ft glacier was days away from collapse. 'We've lost our village,' Matthias Bellwald, the mayor of Blatten told a press conference after the slide. 'The village is under rubble. We will rebuild.' The glacier collapse had been expected for several days, and there have been no reports of injuries. 'An unbelievable amount of material thundered down into the valley,' said Matthias Ebener, a spokesperson for local authorities in the southwestern canton of Valais. Stephane Ganzer, an official in the canton of Valais where Blatten is located, told Swiss media that about 90% of the village was covered by the landslide. 'it's a major catastrophe that has happened here in Blatten,' he said, adding: 'There's a risk that the situation could get worse,' alluding to the blocked river. He said the army had been mobilised after earlier indications that the movement of the glacier was accelerating. Experts consulted by Reuters said it was difficult to assess the extent to which rising temperatures spurred by climate change had triggered the collapse because of the role the crumbling mountainside had played.

Swiss glacier collapse: Situation stabilizes overnight – DW – 05/31/2025
Water that had accumulated behind the collapsed glacier has began to flow downstream, alleviating some fears. Forecast rain means that residents will likely have to remain alert. with dpa along with Austrian and Swiss media Following the dramatic rock fall and glacier collapse on Wednesday in the Swiss Lötschental valley, officials said on Saturday that the situation had eased. One fear had been that the Lonza River, which had been backed up behind the ice, rock and debris, could result in a flood wave. However, officials said the river had found new paths down the valley in the southern Swiss canton of Valais. Construction machinery has been deployed to control the run-off of accumulated water. The municipalities of Gampel and Steg informed residents of the work, saying: "The aim is to ensure the smooth flow of debris and alluvial debris through the bed of the Lonza stream within the villages." Authorities expressed relief that the Lonza River has begun to flow down the valley, reducing the risk of a flood swell Image: Jean-Christophe Bott/KEYSTONE/picture alliance What did authorities say about the Swiss glacier on Saturday? Stephane Ganzer, from the Valais state council, said that there had been no major problems overnight. The situation on Saturday was "currently satisfactory" and the night had been "quite quiet," Austrian public broadcaster ORF reported. The council decided on Friday evening to open a nearby dam, warning residents downstream to make way for the water. Residents were already on alert and ready to evacuate in the case of a dangerous swell of water behind the debris cone. The heat has sped up the melting of the glacier ice and rain has been forecast for the next days. Both could lead to a buildup of accumulated water and increase the risk of further landslides.

Millions of cubic meters of ice and rock were sent crashing through the Lötschental valley and burying the village of Blatten, which had already been evacuated. Water from the Lonza was then blocked behind the almost 2-kilometre-long debris cone. Blatten's municipal president Matthias Bellwald said the village would be rebuilt. "Blatten is under a debris cone. Together we will do what is humanly possible to rebuild the village for the village to have a future. Together we are strong," Swiss newspaper the Neue Zürchner Zeitung quoted him as saying at a press conference.

Christian Huggel, a professor of environment and climate at the University of Zurich, said while various factors were at play in Blatten, it was known that local permafrost had been affected by warmer temperatures in the Alps. The loss of permafrost can negatively affect the stability of the mountain rock which is why climate change had likely played a part in the deluge, Huggel said. The extent of the damage to Blatten had no precedent in the Swiss Alps in the current or previous century, he added.

Flood fears recede after Swiss glacier collapse
An artificial lake building up behind the rubble left by a glacier that dramatically plunged down a Swiss mountainside, destroying a village, is beginning to drain, authorities said Friday, reducing fears of a second catastrophe. The huge barricade of debris formed when the Birch glacier collapsed on Wednesday has blocked the river Lonza in Switzerland's southern Wallis region, fuelling concern the dam of rubble could give way and flood the valley. But as reconnaissance flights and inspections progressed, authorities said the water from the newly formed lake, which has been slowly submerging the remaining houses in the obliterated village of Blatten, was beginning to find its way over, through and around the blockage. "This development is positive, but we remain cautious," said Stephane Ganzer, head of the regional security department. "The risk remains, even if it is diminishing," he told a press conference, stressing that "no evacuations are planned" in the villages downstream in the Lotschental valley, one of the most beautiful in southern Switzerland. The outflow "makes us optimistic and suggests that the water is finding a good path", explained Christian Studer of the Wallis canton's Natural Hazards Service. However, work to pump water from the lake has still not begun as the ground remains too unstable, particularly on the mountainside. The Lotschental valley stretches for just under 30 kilometres (20 miles) and is home to around 1,500 inhabitants. It is renowned for the beauty of its landscapes dominated by snow-capped peaks, its small traditional villages, and its spectacular hiking trails. But its face has been forever changed by the glacier collapse. - One person still missing - Authorities remain on alert, and communities downstream from the landslide, including in the Rhone Valley, which the Lonza flows into, are nonetheless preparing for a possible evacuation. An artificial dam in the village of Ferden, downstream in the Lotschental valley, has been emptied and should be able to contain any downward rush of water, authorities say. One 64-year-old man, believed to have been in the danger zone at the time, remains missing. The collapsed glacier destroyed most of Blatten, which had been home to 300 people and was evacuated last week due to the impending danger. "That shows the importance of early warnings and early action," Clare Nullis, spokeswoman for the World Meteorological Organization, told a press briefing in Geneva. "The landscape will never be the same again. The village will never be the same again. But it is an example of how we can use forecasts and warnings to save people's lives," she said. Nullis said the Swiss had provided a "textbook example" of what should be done, but stressed that not all countries had such highly developed early warning systems in place. The landslide was so heavy it was even picked up by Switzerland's seismographs. "This is probably the most catastrophic event for the last 150 years in Switzerland and probably in the whole Alps," in terms of a rock and ice avalanche, Christophe Lambiel, senior lecturer at the University of Lausanne's Institute of Earth Surface Dynamics, told AFP. - 'Erased within seconds' - The glacier was below the 3,342-metre (10,965-foot) high Kleines Nesthorn peak. In the fortnight before its collapse, a series of falls from the mountain dumped three million cubic metres of rock onto the ice surface. That increased the weight, and with the glacier on a steep slope, it ultimately gave way in dramatic fashion, plunging down on Blatten, at 1,540 metres' altitude in the valley floor. Experts said it was too early to make a direct link to climate change, but told AFP that thawing permafrost in the cracks in the rock likely played a role in destabilising the mountain. Matthias Huss, the director of Glacier Monitoring Switzerland (GLAMOS), said the drastic collapse might bring global attention to the Alpine glaciers, and ultimately the impact of climate change on them. "Often a big disaster has to strike before people realise that something is going on," he told AFP. "It's very tangible: the destruction of a whole village is easily understandable to everybody. People have lived there for hundreds of years -- and everything has been erased within seconds." bur-vog-rjm/jhb
