Blatten Villagers Brace for Potential Flooding After Glacier Collapse
In the aftermath of a significant glacier collapse in the Lötschental valley of Switzerland on Wednesday, authorities have issued warnings of potential flooding in several locations, including Wiler, Kippel, and Gampel.
The Birch glacier, located in the canton of Wallis, suffered a catastrophic collapse, with around three million cubic meters of rock and ice cascading into the valley and onto houses in Blatten. As a precautionary measure, Blatten, with approximately 300 residents, had already been evacuated the preceding week.
Sadly, a 64-year-old man remains missing, as reported by authorities on Thursday. The village of Blatten itself has experienced further destruction, as rising waters from the Lonza river inundated houses that had initially been spared by the landslide.
The mayor of the commune of Ferden, situated in the Lötschental valley, confirmed that "the water is now flooding the houses that were initially spared by the major event."
Wallis State Councillor Stéphane Ganzer spoke of a potential "worst-case scenario" involving a flood wave that could reach the Wallis valley floor and impact the villages of Gampel and Steg. However, this possibility is currently deemed extremely unlikely.
A more likely scenario, according to natural hazards expert Christian Studer, is that a significant portion of the landslide debris will liquefy with rising temperatures and flow towards the valley. This could pose a threat to the surrounding areas.
Prior to the collapse, increased activity at the glacier had been observed for several days, leading up to a clear escalation on Tuesday night and continuing throughout the day on Wednesday.
Climate change has been contributing to the retreat and instability of Alpine glaciers for decades. According to recent studies, Swiss glaciers lost ten percent of their mass in just the years 2022 and 2023 - an equivalent loss to the period between 1960 and 1990.
In 2017, a similar rockslide in the Swiss canton of Graubünden resulted in the deaths of eight hikers and massive destruction in the village of Bondo, despite evacuations taking place prior to the event.
Authorities are bracing for potential ice jams and flooding due to the unstable debris from the landslide. Intervention in the disaster area is challenging due to the risk of debris flows within the deposit. Therefore, evacuations have been extended to villages downstream from the disaster area as a precautionary measure.
- The community of Blatten, along with other nearby villages, faces a potential threat from ice jams and flooding due to the unstable debris from the glacier collapse, highlighting the importance of community awareness and preparedness in the face of environmental science and climate change-related issues.
- In light of the recent glacier collapse and potential flooding in the Lötschental valley, it is crucial for the community to focus on health-and-wellness, especially mental health, as they cope with the challenges and uncertainties resulting from this natural disaster and ongoing climate change.
