Is it correct to say that the video looks far worse than it actually is ?

As in, the dust/mud particles sprayed & floating in the air do not have the force to do harm beyond vision or breathing impairment, similar to the dust from a collapsing building, or the lead shockwave of a nuclear bomb detonation.

Of course, it looks terrible, and certainly somethingbut its not a reason to perish as long as you can stay away from the following water wall and mud current that does strike sometime after.
