Have any of you heard about it?

Apparently it's going to come to Vancouver? That's where I live...

There's not much on the web right now, no one really knows anything.

I'm 99% sure I'm fine where I am, but I'd be interested in knowing any more info.

    7.7 mag - only about 17.5 km deep. Queen Charlot Islands Region. We're gonna hear about this one. It's on the Cascadia subduction Zone - we might be looking at a bigger one in the next few days. Stay safe, beware of a bigger one lurking. That zone produces 9 mags and they've been waiting for the overdue one. Hopefully this will be the largest for now. Maybe it let off enough steam to quell a larger event. Only 17 km deep - will be surprised if there's no casualties unless that epicenter is fairly sparsely populated.

    Edit: Might be safe - epicenter was 86 miles from the nearest population center - Masset, Canada. A tsunami is not real good news though - have to keep an eye on that. I'd be getting out of the region for awhile if I lived there.

    Thanks guys.

    I'll try to keep myself updated on what's happening.

      worrisome for me - my son lives in Vancouver, BC - he moved there in February, because the job situation is better there than here in Ontario and he's been working since he got there.
      Such a gorgeous province but always that underlying danger of the big earthquake!

    There are tsunami warnings for Hawaii and the W. coast. The way those plates can slap, it is a warning people really need to listen to. Better safe than sorry. The quake in 1710 caused problems all over that side of the world.

    The Cascadia Subduction Zone is a dangerous place.

    ...we might be looking at a bigger one in the next few days...
    Sal - scary, but possible.

    Recent findings concluded the Cascadia subduction zone was more hazardous than previously suggested.

    The feared next major earthquake has some geologists predicting a 10% to 14% probability that the Cascadia Subduction Zone will produce an event of magnitude 9 or higher in the next 50 years.

    However, the most recent studies suggest that this risk could be as high as 37% for earthquakes of magnitude 8 or higher.

    Geologists and civil engineers have broadly determined that the Pacific Northwest region is not well prepared for such a colossal earthquake. The tsunami produced may reach heights of approximately 30 meters (100 ft).

    The earthquake is expected to be similar to the 2011 Tōhoku earthquake and tsunami, as the rupture is expected to be as long as the 2004 Indian Ocean earthquake and tsunami.

    An interesting technical research paper from the Pacific Geoscience Center:

    Needless to say, there is much written and readily available online about this topic, but the prospect of a major earthquake still remains a frightening reality for all those living, or with family and friends living on the west coast of Canada and the US - or anywhere along the Pacific coast, for that matter.

    It's very scary. The Cascadia subduction zone is a major threat to the West Coast, as well as across the Pacific.

    We've been lucky in that we haven't been hit since the population exploded. But the Cascadia subduction zone has quaked fairly routinely throughout history and there are native American legends that detail the quakes and tsunamis throughout history.

    IMO, the Cascadia subduction zone is probably the biggest threat to do massive destruction to N. America, with the New Madrid Fault a close second.

      Don't forget Kurt the Cumbre Vieja.

      If that thing ever slips you can kiss the entire east coast of North America goodbye for at least 20 miles inland.

        I didn't forget it and almost posted it, and I have posted about it (La Palma) before. The reason I didn't this time is because there's a few skeptics that say the threat is a hoax. Personally, I believe there's enough info to suggest it is a possible threat. Some claim it will create a super tsunami as high as 1000 ft.

        If real, the threat isn't limited to N. America, it will affect C and S America, as well as parts of the UK, Africa and Europe.

        And then there's the super volcano under Yellowstone that's "over due". It if blows, it would end society as we know it. Many in the US would die within days or weeks from the ash, while the rest of the World would die from starvation due to the sun being blocked by the ash for years, killing much of the plant and animal life world-wide.

          40 minutes or so before you posted this Kurt concerning Yellowstone... I replied to you here mentioning the same...

            I'm happy to report that my son is safe. The earthquake struck about 200 miles south west of Prince Rupert, in the Queen Charlotte Islands.

            The Queen Charlotte Islands, which are also known by their official indigenous name of Haida Gwaii, comprise about 150 islands located north of Canada's Vancouver Island. Their total population is about 5,000. The Haida people make up about 45 percent of the total population.

            The tsunami warnings have been downgraded, and luckily there were no injuries or major damage reported.

            However, had this earthquake struck Vancouver, as I had feared, it would have been a disaster.

            My son just got a raise and is making more money there then he would ever hope to make here in Ontario. So, I doubt very much he's coming back home anytime soon. Therefore, I'm going to have to get used to the fact that he lives in a beautiful but very treacherous area of our country.

            I'm toying with the idea of moving to BC myself - not Vancouver, though. I'm leaning towards the Okanagan area. I've seen a couple of really cool cabins that I would live in, in a heartbeat, as long as I could have internet access, I'd be happy living among mountains and beautiful glacier-fed lakes!

            anyway, even where I am now in southern Ontario, we've had minor earthquakes, and we certainly have had our share of tornadoes. But we can't live our lives in fear, can we?

            I plan on enjoying the rest of my life, fearless, and free!

            Take care everyone!

          That would ruin this nice shade of brown I'm trying to get to.

      We're not out of the woods with Yellowstone yet, Kurt. They think the plume got unhooked from the heat source but it's still plenty hot enough to do some major damage. New Madrid is starting to look pretty scary alright. The good thing about the New Madrid is that the population isn't all that concentrated over most of that area. But that's in old rock with no plate boundaries so a massive quake will resonate quite some distance, too.

      I saw a chart that gave % of casualties if Madrid blows at different magnitudes. They didn't go past 8 mag -- and by the time it got to that point there wasn't much need to, if you get my drift.

      Anyway - I'm not sure the Cascadia is done yet. I've noticed that one or two fairly large quakes always precede a massive one and am very uncomfortable about the 7 mag just experienced. It was high enough 7 (7.7) that maybe it was the big one for this lifetime. I hope that's the case anyway.

    A 6.4 aftershock just struck the area a short while ago.

    VANCOUVER — The Haida Gwaii region continues to feel the aftershocks of a violent earthquake measuring 7.7 that jolted British Columbia's north-central coast Saturday night, frightening residents and forcing many to temporarily leave their homes for higher ground ahead of a possible tsunami.

    The largest, a 6.4 magnitude tremor, struck Sunday afternoon, 136 kilometers south of Masset. There have been over 40 aftershocks in the area.

    They're calling this one "The second largest earthquake to hit Canada since 1949."

    It was scarey last night. All of a sudden the emergency alert came on the tv.

    I just moved to Alaska in June. We where under a Tsunami warning last night. I live on the coast on a bluff. I grabbed my computer and out the door I went.

      Some of that is because the Southern oscillation has been messed up by the gulf oil spill. The water down there is too heavy to flow properly and it's screwing up water currents globally. Some of it's because of deforestation and desertification. And some of it at times is just normal occasional bad weather. We always got occasional bad weather trends depending on if we were in a El Nino or La Nina period.
