We live just South of Pittsburgh in South Western Pennsylvania. We're right on the edge of the Appalachian mountains. I don't recall the exact date, but we heard the rumbling sound approximately 3 to 4 weeks ago. It seemed to be coming from the south east. I saw a few flashes of what I thought was heat lightning. My assumption at the time was that there must be so much heat lightning (cloud to cloud) that it was causing a constant rumble of thunder. However, you usually don't hear thunder from heat lightning, which is what made the sound so out of place.

Does anyone watch youtuber "Dustchsine"? He just talked about this noise in Florida, talked about the awakening of the crustal plate across the southeast and up into Quebec. I highly recommend it, this really might explain this sound.
Just watch the first 4 minutes (roughly) he talks about it there.edit on 21/3/2011 by TheSparrowSings because: (no reason given)
1And I saw another mighty angel come down from heaven, clothed with a cloud: and a rainbow was upon his head, and his face was as it were the sun, and his feet as pillars of fire:
2And he had in his hand a little book open: and he set his right foot upon the sea, and his left foot on the earth,
3And cried with a loud voice, as when a lion roareth: and when he had cried, seven thunders uttered their voices.
4And when the seven thunders had uttered their voices, I was about to write: and I heard a voice from heaven saying unto me, Seal up those things which the seven thunders uttered, and write them not.
1And I looked, and, lo, a Lamb stood on the mount Sion, and with him an hundred forty and four thousand, having his Father's name written in their foreheads.
2And I heard a voice from heaven, as the voice of many waters, and as the voice of a great thunder: and I heard the voice of harpers harping with their harps:
3And they sung as it were a new song before the throne, and before the four beasts, and the elders: and no man could learn that song but the hundred and forty and four thousand, which were redeemed from the earth.

The theory on the videos comments section was it being wind shear from a nearby wind farm. I don't believe that, since all witnesses claim to feel the ground shaking too.
Just putting it out there.
