Massive flood and avalance during my downtown trip

Date: 3/13/2019

I was on the trip to highland village together with my mother and my uncle (who drive). There's a tourist destination. Quite big upstream river with waterfalls, and highcliffs around them. We were passing the road between the river and cliff, then suddenly a massive amount of brown color water came from the peak of the cliffs. Everything in front of us swept away by the flood. We were panicked and turned around but behind us the cliff was collapsed. We were surrounded by the avalance. But insanely we're okay. Just three of us. After it stopped we decide to go back by walking...
