Incident Updates: Glacier Collapse and Dammed River in Switzerland's Lötschental Valley
A critical situation has arisen in Switzerland's Lötschental valley following a glacier collapse. The affected region includes the village of Blatten, where the Birch Glacier experienced a massive collapse, leading to a landslide thatdammed the Lonza River.
Evacuation and Current Risks
Earlier evacuation efforts were undertaken, with approximately 300 people and all livestock being evacuated from the village prior to the collapse. The critical situation now arises from the potential for the blocked river to cause dam failures, leading to flash floods. The Swiss army has been mobilized to assist in managing the emergency and supporting affected villagers.
Environmental Factors
The glacier collapse is an outcome of escalating glacial retreat in Switzerland caused by climate change. The country has observed a 4% decrease in total glacier volume in 2023, showcasing the severity of the issue.
Flood and Debris Risks
The river blockage increases the likelihood of a sudden dam break and subsequent flash floods. Additionally, there remains a risk of further debris avalanches as the ground beneath the landslide may still be unstable.
Government Response and Support
The Swiss government expressed condolences over the incident and is working to implement measures to support those who have lost their homes during the glacier collapse.
