What's Causing the Mysterious Rumbling Sounds in the Sky?

[kdog1982]

Hi,I'm new here,so forgive me if I don't follow protocol correctly.

I have been following reports across the world of strange rumbling sounds coming from the sky.
Some last just minutes,others many hours.
Most reports that I am looking into deal with a mechanical thumping,humming sound not associated with any earthquakes,plane engines,or any other sources.

Things I am looking into are fracking locations and possible atmospheric conditions causing some sort of sound propagation.

Any thoughts on this?
Thank you in advance.

How about thunder?

If you want us to have anything to say about this, you will have to point us to the reports you are reading.

You really havn't given us much to go on. Strange rumbling sounds could have a thousand different sources.

My tummy. Around noon.

I apologize for not providing a link.

Here is one that a friend is compiling that is a list of such sounds.
And,no it's not thunder.

And here.

Ah. I see.

How are these reports being gathered? How do you know these people?

And how do you know it's not thunder? Wait, a more well-formed question: how do you rule out thunder as a reasonable explanation for some of these anecdotal accounts? It is certainly the most plausible explanation for some of them.
