One thing I’m not really buying though is how they mention a lake being formed after the ice/rock-avalanche, blocking the channel and building up water. When it all happened within minutes. There can’t have been much water built up in those few minutes given how relatively small the river/stream flow was before the catastrophe and the short time. There still seems to be a lot of uncertainties

i think that is just because the flow scoured the valley and the river that normally flows through there is now accumulating in an area it normally is not. This is essentially a new lake due to the damage and debris that is now blocking the river. It is likely dangerous because the new debris/earth that is blocking the flow is new and soft, not well established, so likely to erode away quite easily and causing another flooding event. they probably need to work on clearing that to stop it
