Its showing as a 2.1 with a dept of 6.50 km. (4.04 miles)
Regardless of what it "is", that seams like it was a very scary thing to hear. Please keep a recording device handy as I for one would love to hear it.

It's happening all over the world and no one knows what it is. I have read about it a lot on the internet but no news station has covered it yet that I know of. Would be nice if a news station would try to investigate it. And Scientists, no one is talking either. So very weird.

The rumbling noise abruptly cut off, restarted and then cut off again? Did I get the sequence and the fact the transitions from noise to silence was abrupt, correct? That is something a bit new and if this is related to the others then I'd say it rules a few things out. I can't see where naturally produced noise from geologic events would have sudden drop and restart points. Something mechanical might though....or something generated from Space.
Hmm.. The way this is all developing over time is as interesting as the base phenomenon itself.
