It wasn't an earthquake. It was the province of Quebec trying a new way to seperate from Canada.
felt it in brooklyn new york. thought i was having an acid flashback.
Felt here in Queensbury NY. PC Monitors shaking, felt chairs shaking. Eeerie.
I felt it in Algonac, Michigan. I was sitting on our sun porch, and it felt like vibrations under the floor. It was a little dizzying, but I knew it had to be an earthquake. It certainly wasn't a big truck driving by!!
South end of Ottawa... pretty violent... felt like it would go on forever. Things fell off table and pictures needed straightening afterwards. A few people freaked out. Paranoia has begun on one of the local radio stations... sheesh..
Im in Barrie Ontario, Canada. It shook my whole house. Was pretty wild really, we dont get earthquakes up here. This was a first for me. Crazy EH!!!!
We felt it in Detroit, MI. I am just outside Detroit and it shook our whole office building. Things rattling on our desks, cubicles shaking... reminded me of my days in California.
Felt it here in NW Suburban Chicago, too...
Wow felt this in Cincinnati, Ohio for several seconds
Felt in Schenectady, NY.
Felt it in Fairfield, NJ.
Really the strongest quake I have ever felt and I have been in 3 very small 4.0s in LA. Here in ROCHESTER, NY my desk swayed quite a bit, so much so that I almost could not right myself in my chair and I almost thought I could feel the floor moving. It was amazing. Rather scary in a way.
Felt it here in Albany, NY – my officemates and I got all light-headed and could feel the ground shaking under our feet.
Felt it in Binghamton NY. Was sitting at the dining room table working on the computer when my chair began to shake, very slightly but definitely felt it. We've had small earthquakes through this area before so I thought that this could possibly be another. And apparently it was.
We felt it in Schaumburg, IL – 4th Story Office Building swaying.
