joelmax writes "A magnitude 5.5 earthquake hit central Canada this afternoon, rattling buildings from Windsor to Montreal to several US states. The epicentre of the quake was in Quebec, 61 kilometres north of Ottawa, according to the US Geological Survey, and struck at 1:41 pm EDT." If you felt this quake, it would be great to put your location in the title of your comments, below — with lat/long coordinates even better.

    I was in a boardroom on the 6th (top) floor of our building for a 1:30 pm meeting and just as we're getting underway the table and chairs were shaking. Was pretty heavy for about 20 seconds and then faded off over the next minute. We're a lot of government buildings so the policy is to evacuate. We actually tried to continue our meeting but then they finally got to our floor to check it out they found us and told us to leave. As you can guess, no more work is really being done today. It's pretty exciting for us as we don't get this here.
    One interesting note, when I did go outside most everyone was on their cell phone and several were stating that they couldn't get service. I would guess because of the increase in volume at that time.

      I didn't get touched, I'm in Alberta, but our Branches out in the Toronto Area felt it quite a bit.

      Latitude = 43.6325, Longitude = -79.6601
      Lat = 43 degrees, 38.0 minutes North
      Long = 79 degrees, 39.6 minutes West

      Our only Tech out there emailed and asked if our systems were capable of withstanding 5.5 Earthquakes.

        We emailed back "We don't know!!! Is everything running? Power okay? Any one sent in any IT Requests?"

      To which he responded, "Everything looks good. We're all fine by the way, thanks for checking."

        If you're in an area that isn't hit often, it's smart to take it seriously, even though people in other areas treat the same magnitude earthquake something less-serious. People in the latter place are used to handling the after-effects, and the infrastructure is made to handle it better. In other words, the context matters as well as the event.

    • by adonoman (624929)
      It's certainly Central Canada based on east/west population distribution - although it may have shifted west in the last while, I believe that the population center of Canada (based on a center-of-gravity type calculation with population density) was calculated to be just north of Toronto. You can pretty much just discount everyone in Northern Ontario, Manitoba and Saskatchewan, and the maritime provinces. Then you have BC/Alberta balancing off Quebec, and Southern Ontario gets split in half.

      I felt it in Toronto as well. I was 21 floors up, so it was pretty intense. Lights, doors, etc were swinging. According to my security guard, someone on the upper floors of one of the buildings here saw their furniture move across the floor.

      Once I made my way down 21 flights of stairs, I spoke to some of my neighbours. About 3/4 of all the residents brought up the G20 jokingly. Pretty much sums up what we think about the event, huh?

    I'm from California, a 5.5 is about a large truck going by. One time, we had a 5.4 in the Bay Area and it was one of those quick jolt ones. I thought the fat guy in the apartment above me fell down. I think we had a 5-something last week, I didn't notice since I was at Disneyland.
    • by canajin56 (660655)
      5.5 is "Can cause major damage to poorly constructed buildings over small regions. At most slight damage to well-designed buildings" It's only "a large truck going by" if you're not really that close to the epicenter...if your criteria is for an earthquake that you're not near, then whatever, a 9.9 you can't even feel at all (if you're on the other side of the world).

        I remember a 5.6 aftershock from the '94 Northridge quake, and I was in my apt. about 8 miles from the epicenter. It was a little more than a large truck going by, but it was still no big deal.

    by Anonymous Coward on Wednesday June 23, 2010 @02:34PM (#32669260)

    It's in part of Canada that is prone to earthquakes, extending roughly along the Ottawa and St. Lawrence River Valleys. The increased activity along here is related to two factors: 1) this is an old "suture" [wikipedia.org] where pieces of continents were accreted onto the rest of North America a long time ago (the later half of the Paleozoic [wikipedia.org]) culminating in the building of the Appalachian Mountain system (the Appalachian Orogeny [wikipedia.org]); 2) the suture stopped being an active plate boundary after the continental pieces were fused onto the continent, but crustal stress still occurs because of the relatively "recent" melting of the continental ice sheets ~10k years ago. The weight of the couple kilometres of ice during the glaciation depressed the crust, and much of central Canada has been experiencing isostatic rebound [wikipedia.org] (i.e. rising back up again) ever since the weight was removed. That process slowly deforms the crust, and when the stress gets too great the rock moves, generating earthquakes. The stress tends to get released along old zones of crustal weakness (i.e. #1).

    This seismic hazard map [nrcan.gc.ca] by the Geological Survey of Canada shows the increased risk along the St. Lawrence River rather nicely. More details here [nrcan.gc.ca].

    Having said all that, the level of activity in this part of Canada pales in comparison to earthquakes in the area of an active plate boundary, such as California, where the deformation rates are higher, the earthquakes more frequent, and often higher magnitude. It means that building codes along the St. Lawrence-Ottawa River Valleys are fairly strict when it comes to earthquake resistance, just in case, but a significant earthquake is still outside most people's everyday experience. I'm sure people are freaking out (I'm ~1000km away, so I felt nothing).

    Just making sure everyone knows their facts: Remember magnitude doesn't measure INTENSITY of shaking but instead amount of energy released at the moment the earthquake begins. Yes, the scale is logarithmic. So, a 5.0 earthquake is 32 times stronger than a 4.0, with a 6.0 releasing more than 1000 times the energy of a 4.0. Feeling that 5.7 on the 15th of this month here in SoCal, the first thing that pops in my head is "How strong is this one going to feel - is it the Big One"? It's actually quite cool to be able to feel the P-waves arrive first followed by the S-waves if the earthquake is both strong enough and far away enough for speed differences to be noticed. It's also nice to notice someone mention the glacial rebound earthquakes of areas in far NE U.S. and S.E. Canada - that's the first thing I guessed the moment I heard about it.
