This story is developing. We'll bring you the latest information as we get it.
We felt the tremors here in downtown Syracuse. Everything stopped as the whole floor of my office looked around to see who was shaking the cubicles, and then all of the expressions changed as people realized what was really happening. Intensity of the shaking seemed to ebb and fall like a wave over the 10 to 15 seconds that it lasted, and then the incredulous conversations began. Quite a memorable day!
Felt it here in Hamilton near Toronto, we don't get these usually what the hell is going on? My desk where my computer is was shaking for like 20 -30 seconds, scary.
Felt in St. Catharines, ON. We could see the walls in the office moving. Lasted a good 2-3 minutes.
Sorry, meant it FELT like 2-3 minutes. No shaking, swaying enough to make you a little dizzy. It was wierd.

Just because you didnt't feel it doesn't make other peoples comments BS.. my mom works less than 5 KM away and she said she didn't feel anything at all when I called her. However at my home my couch was shaking and we ran outside.
