A massive landslide in the upstream area of Wanli Creek in Hualien County, Taiwan, has created a natural dam, forming a lake. Authorities predict this lake could overflow within the next ten days, posing a potential threat to downstream areas. The landslide, triggered by recent geological activity, has blocked the creek, causing water levels to rise rapidly. Officials are currently assessing the extent of the impacted zone and potential risks to nearby communities. Evacuation plans are being prepared, and residents are being warned to remain vigilant. The potential overflow could affect agricultural lands and infrastructure along the creek’s path. Continuous monitoring of the lake’s water level and stability of the landslide debris is underway to mitigate potential disaster.
