Loud Boom Heard in Vancouver

I was near W 11th and Alma when it happened and it sounded like it was coming from the North.  My first thought was that it was an explosion.   It didn't rumble like thunder. 

I was in North Van and heard the boom which felt in close proximity. Both of us in the room heard it and looked at each other - I also was watching the funiture to see if anthing would sway - but there was none. It was deep and rumbled. There was no mistaking it. The only thought would be thunder. This is the first thing I've seen or heard even mentioning it.

I heard it - it woke everyone in our house.  I looked outside and concluded that it was thunder, but it sounded closer than any thunder i've ever heard and there wasn't any other thunder. But immediately afterward there was a really heavy burst of rain.

it is near the ocean. I wonder if it was a sound wave. That is completely fascinating. Like a sonic tsunami.

 Has the news been covering this any more there?  I was starting to believe it was some oceanic soundwave but I just came accross this site.

http://home.att.net/~thehessians/mysterybooms.html Some kind of global disaster watch site.

The link looks funny but it is just some ones home att account. There is a list of probably 20-30 of these events that occoured within the past two years all over the world.  Maybe I will try to email them and let them know about this one and see if they will let me post their article here. 

Now I am still not convinced that it was not some military test or something?

Puzzling. 

WOW - It is great to be able to share news worhty information with those that are intersted! I heard it too, I was in North Van with Flannegan, we came through the front door,which faces north, at about 3:23am, I made my way over to the main window, facing south, to close the drapes. I thought a breath of fresh air would be good since we had been in a bar so I opened the patio door (south facing). Since it was late I was about to suggest we wind down, I turned to walk back to Flannegan, who was in the kitchen area of my small(ish) apartment near the top of Lonsdale, again facing north, when the said noise occured. We both looked at each immediately and wonder aloud, "what was that?". I turned back to the open patio door (south facing), because I was still close to it, about 4.5 feet away and stuck my left ear out. The noise was STILL there. It was loud, long, and seemed to be coming from a sonic interruption, as though the sound barrier had been broken. It did sound like it was from the ground not so much the sky but there was no vibration after. There was no light in the sky (or the ground) and it did not re-occur. Since this seems to be the "go to page" for "newsies" I hope this doesn't sound like to an odd question but can the sound barrier be broken under ground?

Thta's a great question. I am not sure but I am going to try to look into these sounds a bit more just for fun. It is strange how the media does not cover this very much. I wikll keep updating here if I find anything.

Has anybody figured out what the loud boom was?  Last night, 2009Feb11 at 3:15am I heard a boom which sounded like it originated from the ground and shook the house... I hear this once in awhile in the middle of the night... really wonder what it is!!!!!
