The cups hanging on the underside of my cupboard were rattling. I've hit one or two reaching for a light switch but not all of them. At first I thought 'quake', but, because it was windy, I just figured it was that. I was wrong.
Felt it here in Batavia, NY parts shelf started rocking back and fourth slowly for about 20 seconds
Wow...a tornado in Toronto last year, now the city gets hit by an earthquake.....this stuff never happens here....what's next ??...the Leafs in the playoffs ??........no..sorry.
Quake felt in Toronto, thats not all of Canada. Canada is not one big state like most people think. We have province's
Wow a minor earthquake. You all know the CNN drill for this. Panic! Terror! 2012! End of the World! Give me a break. About as newsworthy as rural Maine rotary club meeting.
5.5 magnitude quake strikes Canada; WOW all of Canada felt this???
What a LAME INCORRECT HEADING!
I'm feeling it now! And it's spectacular!
I felt it in Brooklyn, New York.
I SURVIVED EARTHQUAKE 2010
Sorry about the quake everyone. I punched the earth. My bad.
Native Californian here. How in the world did you guys feel that earthquake that far south in the states??? I have been through many 5.5 earthquakes and there is no way you would feel it living in PA, NY, WV.
Megan, I don't know what to tell you – but we DID feel it here. It was all over our local news.
I live in Ohio and felt it - my chair shook
Megan, this whole are is pat of the Canadian Shield. Also called bedrock. Can't get anything harder than that so when it shakes ... it REALLY shakes.
40 miles from upstate NY to the epicenter. 300 to NYC.

The reason the quake was felt in a wider area is because there is fewer earthquakes in the Eastern Part of the United States so there are fewer breaks in the land. This allows the shockwaves from the quake to travel over a further distance leading to people in a wider area feeling the quake. This differs than what we may feel in California because Earthquakes are a common occurance so there are more breaks in the land to where the shockwaves would stop leading to less people being able to feel a similar size quake here for example
I felt it here in West Chester, Ohio...a suburb north of Cincinnati. Wasn't very strong, but my chair rocked back and forth for about 10 seconds.
Syracuse NY
I live north of Toronto and I felt it. Having lived in Californa .. and taken the ride there too, I have to tell you that an earthquake on bedrock close to the surface (12 miles down) is ALOT different than CA where they tend to be deeper and ground cover a lot different. Got to love the sound of the rumble though. It got all of the horses attention.
I live in Ottawa which is 53 km (32 miles) from the epicentre. I was outside when it struck, man, never felt something like that before. My antique clock stopped, at least I know it's running 3 minutes slow, hope everyone is o.k.
