The video you've seen shows a flash flood moving massive boulders like they're nothing as it flows down a flood channel. Flash floods are sudden and rapid flooding events that can be caused by heavy rainfall, dam or levee failure, or other factors. Flash floods can be extremely dangerous and destructive, and they can occur with little or no warning. When flash floods occur, they can pick up and carry large objects such as boulders and trees with incredible force, as seen in the video. This is why it's important to stay away from flood-prone areas during heavy rainfall and to follow evacuation orders if they are issued.
