Mud Flood Questions

Mud Flood Questions is less about if a mud flood occurred, and more about who may have flooded us. The flooding of mud, and in some areas sand, seems to have been done strategically. Are we in an enclosed environment?
A shot in the dark. Dirt is an easy fix for stopping the spread of radiation. I do not think that atomic bombs were used but a type of energy that produced a negative outcome and the way to neutralize it was dropping sand or dirt on the affected area?
That’s a fascinating idea. I had always assumed that the dirt/mud was a byproduct of some cataclysmic event (seismic, ballistic, etc). While it very well may be, I have never broached the possibility of it being intentional with a purpose beyond the obvious result.
