A cryoseism, also known as a frost quake, may be caused by a sudden cracking action in frozen soil or rock saturated with water or ice. As water seeps down into the rock, it freezes and expands, putting stress on surrounding rock. This builds up until it is relieved explosively in a cryoseism. Another form of cryoseism known as an ice quake, is a non-tectonic seismic event caused by sudden glacial movements, sometimes due to the formation of a thin veneer of liquid water under a glacier from surface melting. Usually, a glacier would stick to the rough bedrock, but the hydraulic pressure acts as a lubricant, allowing it to slide up to many metres at once. This type of cryoseism can last for tens of minutes. As the requirements for cryoseisms to occur are not yet defined, their prediction is still not possible and constitute a significant factor in structural design and engineering. Links have been made between global warming and the frequency of cryoseisms.

I'm kidding... but actually not. No proof, just a guess. Everything has the appearance of subsurface noises, vibrations, etc., not a sky phenomenon.

I live in B.C and I haven't heard or felt anything at all. I have friend's who live on the Island and have not reported anything when I contact them. This whole sky sound thing is starting to become a mass form of hysteria I think . People are taking normal everyday occurrences and making them out to be something they are not. The video from Vancouver Island is funny because she said they were going to take the barn down anyway's and the wood looked rotten from the video, my guess is the barn fell down on its own. Just like those people in Saskatchewan in the winter who said the sky sound's sounded like snow plows.
O.K. Saskatchewan.....winter....snow ...snowplows?????
This is all starting to get goofy as far as I'm concerned. Until I hear it or feel it for myself , I'm calling mass hysteria.
