Well they heard them in Manitoba, and Alberta. A whole town and mayor heard them. Then all the way to the far side of Vancouver island on the Pacific, Sooke BC.

Now if it was just an earthquake it really would be quite common and "normal" like that scientist interviewed by CTV said.

Normal is something we would all have heard in our lives, even our grandparents would also have heard. But alas, we're the only generation lucky enough to encounter this normal Godzilla sound, in 2012 at that.

They also heard the same sound in Mexico, LA, UK, etc.

268-270 miles away

I'm a Manitoban, I didn't feel a thing.

From what I understand, Manitoba is relatively earthquake-free although we do have shale deposits, fracking is in our future.

I'm beginning to think that many of these videos are reproduced from the same sound file from a seen in the Tom Cruise movie, "War of the Worlds." There is a very convincing video expose' on YouTube.
