Just had one here in Toronto (~1:43PM).

Sitting at our desks, the whole office felt the building rock forth and forth for about 15s. What's wild is that we got forewarning: we were on a con-call with Ottawa (nearer the epicentre) and they experienced it 45s before we did.

Anyone else?

Im in pittsburgh and the whole building started shaking about 10 mins or so ago. They are doing a whole bunch of construction on this building, so I just figured thats why. No idea it was an earthquake

I should get ready to shake in about 20 minutes according to your measurement.

No shaking here in central Maine, but I wouldn't have noticed anyway - there is a lot of heavy truck traffic on our road and I would have laid it off to traffic.

Yup, I'm in downtown Toronto and it woke me up. It only lasted 3secs though. I thought someone bombed G20. =_=

Apparently, aftershocks are expected.

I'm right at the waterfront. I'd love to see if tremors might be visible in the water. Any bets?

If the water is VERY still, maybe. It would be interesting to see ripples at the edges of pools and channels from the shaking.

I felt it in Buffalo, NY. My first one.

A magnitude-5.0 earthquake struck at the Ontario-Quebec border region of Canada on Wednesday, the U.S. Geological Survey said, shaking homes and businesses from Canada's capital in Ottawa on south to the U.S. state of West Virginia.
There were no immediate reports of injuries or damage.
The midday quake was felt in Canada and in a number of U.S. states, including Michigan, Ohio, Pennsylvania, West Virginia, Vermont, New Hampshire, New Jersey and New York.
The USGS said the quake occurred at a depth of about 12 miles (19.2 kilometers). The agency initially said the quake had a 5.5 magnitude, but later reduced it to a magnitude-5.0. The quake occurred at 1:41 p.m. EDT (1741 GMT), the USGS said.

I like their reporting...

"The midday quake was felt in [that vast, uncharted and undifferentiated wasteland (ye Gods, do they even have borders up there or they just some monstrous orgy of anarchical tribespeople) called Canada] and in a number of U.S. states, including Michigan, Ohio, Pennsylvania, West Virginia, Vermont, New Hampshire, New Jersey and New York."

This is pretty surprising to me. I wasn't aware of a fault that runs east/west like this.

How do you know what direction the fault runs?

Just saw the news. The Salvation Army building in Waterville was evacuated during the quake. It's an old building, and it apparently shook noticeably. That's just about 40 miles from here.

We have a fault a few miles from here running through Missouri, go figure.

It's called the New Madrid fault. We get earthquakes AND tornadoes!

I'm making an assumption based on the east/west line of locations where it was felt.

Initial news reports we read out here said that it shook TO out to Ottawa. So, sideways, yes? :smile:

You and everyone you know okay, Dave? My parents are just east of you. I need to check on them.

I read that the cause was isostatic re-stabilization, that make sense to anyone? (Since the region was covered in glaciers 20 000 years ago)

Any other theories floating around out there, maybe aliens or the government?

Well, no. The places where it is felt will radiate out from a point - the epicenter - which is in Quebec.


What you're suggesting is that we also experienced an earthquake here near Toronto. We didn't. Was just felt the shock as it radiated from the epicenter.

has anyone notice that the quakes are getting more frequent and spreading globally.... i wonder what that oil volcano in the gulf will do... could it cause a collapse of the sea floor and release a tsunami?
