Nothing like that has been reported in Australia. I have friends in Melbourne who can confirm that the plot on the map is false. I wouldn't be surprised if this is some stupid viral hoax.
A stupid viral hoax u say? hhmm... As u wish.
However, and perhaps this was a blunder on the part of the MSM which should have just ignored this, they (MSM) have gone ahead to confirm that truly, there are "groaning" sounds being heard from all over and although they have tried to down-play this, by implication they have still agreed that something is up, for u who believe everything they spout, perhaps u should listen to what they have accidentally "made-public". We are beyond speculations of this being a hoax, it is now an issue of "what it is". Ponder that.
I find it sad though that some are churning out fakes, but in most cases they are obvious. Good morning.
