Scientists have captured a mysterious hum coming from deep inside the Earth, but they are still no closer to working out what it is.
It has long been known that the Earth constantly generates a low-frequency vibrational signal.
The first attempt to detect this hum was made in 1959, but it wasn't until 1998 that scientists finally proved its existence.
Since then, there have been hundreds of attempts to record the Earth's hum, but they have all been made using seismometers on land.
Merry Christmas to you too. I have heard a hum in some places, but the places were close to a flooring mill, the rock hills may have been collecting the noise and making a hum out of it that you could hear a mile away. Other than that nothing other than the normal sounds coming out of the old copper mine shafts and shaft vents up in the hills of Hancock. Those sounds bounced off of buildings. It sounds spooky when you got near those vents and shafts. Most were capped about thirty five or more years ago now, so people up there might not even notice them anymore. I used to play around those shafts and we used to go through the fences and toss rocks down them.

Not that I don't agree - but - I want to HEAR IT - or it doesn't count.
Kind of like having seismologists telling ya 'We just had a 3.6 EQ'...
Didn't feel it - didn't happen.
And yesssssssssssss, I know it might have , but, no one cares if it doesn't effect them, they can't feel it, the can't hear it, etc.
Well, for the most part peeps are like that.
Oh - Merry Christmas Mouse!
Eventually, they were able to determine that the Earth's natural vibration peaks at several frequencies between 2.9 and 4.5 millihertz.
