I hear loud and long rumbling all the time at work, and at home. I have discovered that while I am at work, a distant plant that is located directly across from this location, but on the next large hill, is making those sounds, and at home what I am hearing is the chemical plant burning off God knows what early in the morning. I believe I read on the thread here that the sounds are being attributed to a phenomenon called 'ducting'.
If the atmospheric condition that causes superrefraction bends the beam equal to or more than the earth's curvature then a condition called ducting, or trapping, occurs. Ducting often leads to false echoes also known as anomalous propagation or simply AP.
I think the bigger question here is why is 'ducting' going on apparently around the world, what is causing the beam to have this anomalous curvature? It seemingly is happening more than usual. Or maybe we are just paying closer attention.

I don't think a mythical figure has anything to do with this, i think it's momma nature getting ready for something.
