This story is developing. We'll bring you the latest information as we get it.
We live about 50 miles directly due south of the quake area; we felt it here for almost 30 seconds. Oddly; happened to be watching CNN at the time. There was definite "wave action" ; like in a pool with vertical movement too. The funny thing is we have a lot of road construction here ; and "tremors" are somewhat normal ; lasting maybe 5 seconds at a time... this "one" felt like their blew up the entire area. No damage to house ; a few things fell ; that is about it. I had to time to realize this was no normal "road work" ; get up and walk outside - it was going on the entire time. My dogs were freaked bigtime.
Felt it over here in J.P, Boston MA. I was sitting in my car for lunch when I felt it shaking. Thought it was the wind at first but there was barely a breeze. Felt it for like 10-15 secs.
Sorry about that! My fault, my fault. I tripped on a harp!
Felt it here in Buffalo, New York also. Our office chairs were bouncing up and down and the pictures were banging against the wall. People in the elevators also said they were swaying back and forth.
it was realy scary i wason my computer and all of a sudden it started shacking and i thought there was a truck driving passed my house !
I live in North Bay Ont. I was sooooo scared and my brother and i were hom alone i started frecking out!
Don't worry, Its just Quebec trying to separate from Canada again. Only this time they are digging a tunnel.
Was told it was felt in central MI area.
Didn't feel it in Williston, VT no clue why but several surrounding areas did.
Shook dresser, vibrated picture to edge of it, mirror on wall danced in Lindsay ON Canada. Twice for mere seconds with short interval inbetween
I felt it in a van down by the river. Milw, WI.
We did not feel it in Monett, MO.
Felt in Columbus, Ohio
Its Nature's way of hating on the G8/G20.
Why would CNN report what is going on in Toronto if the quake happened near Ottawa? We have more than 1 city in what we call provinces. It's like if a quake happens in LA do you think our news agencies are checking in on Colorado?
