Earthquake!

Any damage?

USGS clocks it at a 5.5 (updated to 5.6). This is what it looked like on Twitter:

    5.3? doubt it

  2. February 13, 2012 at 1:16 pm

    Hate it when that happens. That one site says it was a ways NE of Eureka. I’m guessing from the map maybe between Trinidad and Hoopa? Supposedly about a 5er.

    Shook the house pretty good and knocked some stuff down upstairs is all….so far.

    linkage, initial report a 5.3 in the north east.

  4. February 13, 2012 at 1:18 pm

    5.3? doubt it

    My first guess was a 4 or 4.5, but I also figured it depended how close the epicenter was. With it being that far NE of us, 5 sounds good to me. Maybe even stronger at that distance.

    Depends where you are. Our old house shakes pretty good.

    Earthquake happened 10 km (6 miles) WSW (237°) from Weitchpec, CA according to weather service.

    A moderate jolt in McKinleyville, first mistaken for a strong gust of wind, sound-wise. I didn’t feel it for more than a second or two.

    Some students in McKinleyville thought it was the construction site on Central Ave. That place has been rattling houses blocks away for a couple weeks. You’re sitting quietly and then your wall hangings begin vibrating for 20 minutes. Wonderful.

    9 minutes elapsed between the earthquake and the tsunami warning center e-mail. Obviously won’t help us if a tsunami is generated by a local earthquake.

    Yup, that’s why they say that if you’re in a low-lying coastal area and there’s strong shaking you should go ahead and head to higher ground immediately, don’t wait for the tsunami warning.

    I was in the Arcata area when this was happening today, and it seemed pretty mild, so I didn’t worry about it. But 5.5 is a substantial quake — I wonder if there was any significant damage out in the Weitchpec / Hoopa area, closer to the epicenter?

  18. February 13, 2012 at 2:38 pm

    I grew up in New York and it scared the daylights out of me in Trinidad.

    I can only speak for myself, but I’ve lived up here almost 40 years. I’ve been through any number of earthquakes, big and small, and even the small ones scare me. If nothing else, the BIG ONE might well start as a small one, so they’re all scary.

    The one thing that always goes through my mind when the house starts shaking is whether the small shaking is as bad as it’s going to get, or will turn into a bad one. Even after it stops I always worry it may start again.

    …that’s why they say that if you’re in a low-lying coastal area and there’s strong shaking you should go ahead and head to higher ground immediately, don’t wait for the tsunami warning.

    One thing I never hear the “experts” mention regarding warning signs is the ocean water visibly receding from shore. I’m not sure but I don’t know that I’ve ever heard of a serious tsunami that wasn’t preceded by the water receding just prior to it coming back in the form of a tsunami.

    I believe I read in the big Thailand quake that the water receded so far back that people walked down to explore the newly uncovered beach before the tsunami struck. Those folks are history.

    I’ve heard other similar stories, including one from Hawaii during the Hilo tsunamia: Kids were at school and the water suddenly receded, uncovering the rocks and trapping fish in pools. The teacher told the kids to go down and grab the fish. The kids never came back, assuming the story is true.

    I guess shaking ground is an obvious warning sign, but it would seem to me the water receding might be even more obvious, and that would happen even if the quake was generated across the ocean where you wouldn’t feel the shaking.

    Fred,

    good point about tsunamis often being preceded by an unusual (fast and beyond the normal tidal flow) draw-down of the water level at the shore.

    The water receding like that can certainly be a sign of an impending tsunami, but if you’re in a low-lying area and feel the strong shaking, I wouldn’t wait around to watch to see if that happens. For one thing, I’m not sure that always happens before a tsunami (perhaps someone who knows more about this could chime in on this point), and for another thing, you’d be losing potential evacuation time as you waited and watched.

    But it’s certainly a good thing to know about, because sometimes quakes aren’t all that noticeable when you’re outside, and so you might not notice the quake but do notice the receding water, and in that case it would probably be wise to head to higher ground (and tune in to your radio, if you have one, on the way).

    I hope nobody got hurt today.

  22. tra

    If the quake generating the tsunami happens across the ocean, then most of us will hear about it long before the tsunami arrives, thanks to radio, TV, the internet, phone calls, etc. But I suppose if someone was, for example, backpacking along the Lost Coast, the first sign they might see could be the receding water.

    The most dangerous situation for those of us on the North Coast would be a strong quake centered just a few miles offshore, which could generate a strong tsunami that could reach shore within minutes. In some cases, depending on how close the quake was, and how far out into the lowlands / dunes / beach the person is, the person may be unable to flee in time, no matter how fast they react. But there’s no way to know for sure if you’re in that situation, so, you might as well try.

    I guess the tough question would be whether to head for a nearby, but not-all-that-high dune or hill, running the risk that the tsunami will be high enough to overrun that location, or to head toward a higher-up, but also more distant hill, taking the chance of being caught in the low-lying area while en route. For example, if you happen to be at the Manila Dunes, should you head to the lookout (which is above the level of most tsunamis, but potentially susceptible to The Big One) or try to head toward higher ground in Eureka or Arcata, and chance being caught by the tsunami somewhere along the way?

    If you are at the beach or live on the peninsula, do not try to drive away from a local event. A few inches of road shear and you will be bumper to bumper awaiting a wet ride with all of the other escapees.

    A shoreline or bay drawdown is not required for a tsunami. An earthquake is also not required as it could be generated from an undersea landslide (or an asteroid for that matter).

    A Cascadia event is probably the only local event that poses a mortal danger to property and life in our area. Distant source events (Alaska, Chile, Japan) will trigger the sirens and spare our communications and provide some level of calm evacuation. But forget the sirens for a local event.

    Currently rated a 5.6. We live in Dow’s Prairie and the house (on a slab foundation) shook pretty good for about 15 seconds. No jolts and not a roller. No damage. Nothing moved, except one cat, momentarily. Second cat sat through it outside, looking at my husband, who had gone out to see if there were trees rocking or anything, like it was his fault.

    For a few seconds I wondered how much it was going to ramp up, but then the shaking subsided.

    Does anyone remember an earthquake with this epicenter location? I don’t.

    There was a tsunami here many years ago and a bunch of clammers at Moonstone Beach saw the receding ocean and knew enough to seek high ground. The whole basin filled up shortly thereafter, not sure about the parking lot. One of them told me about it. I think it was in the 50s or early 60s. Not the one that hit Crescent City though.

  28. February 13, 2012 at 5:34 pm

    Does anyone remember an earthquake with this epicenter location? I don’t.

    I don’t,either, and that was the first thing I thought odd. Usually they’re from the SW or SE. Mostly from the SW. I don’t ever recall one from up there.

    …The whole basin filled up shortly thereafter, not sure about the parking lot.

    That might have been back in the 60s. Perhaps the Alaska earthquake?

    A retired Eureka police officer I used to work with told me that he was down in Old Town after the Anchorage quake (64?). To paraphrase: “I never saw the bay drop down so quickly.”.

    Fortunately, no tsunami that time.

    I also heard a story from a retired deputy sheriff who I worked with at the same time. Authorities believed a tsunami might occur so ordered some deputy (not the one that told me the story) to drive to the North Jetty and report what he saw, or some such. He refused. No way he was going out there, he said, or so I was told.

    I have no reason to doubt that story.

  29. tra
    February 13, 2012 at 5:48 pm

    That’s a funny story. It’s as if lightening strikes were feared and the deputy was ordered to head to the top of the tallest hill around and climb the tallest tree and then report back. Yeah, thanks, but no thanks!

  30. February 13, 2012 at 5:57 pm

    Made me wonder about the mindset of the people in charge that wanted him to go out there.

    Fred,

    Of course the story may have been exaggerated for effect right from the beginning, or as it was passed from the deputy in question to the retired deputy and then to you, and.or embroidered a bit over time. That does tend to happen, because we humans tend to like to tell and hear good, entertaining stories more than we care about their accuracy.

    If I had been the deputy, and someone actually did ask me to go down to the Jetty to watch for a tsunami, I might have suggested an alternative: Table Bluff and a pair of binoculars!

    Latest has it as a 5.6, 17 miles ENE of Westhaven (about 6 miles wsw of Witchepec) and at a depth of 20 miles. I suspect the depth was why it didn’t feel stronger.

    I felt it in Crescent City, but it was just a gentle rocking. I felt a very short movement, and knew that it was a quake. Then about a minute or so later was a more sustained rocking. My house is on post and pier, but nothing moved. Let’s look at this quake as releasing the built up pressure so that the Big One doesn’t happen.

    Richard, this speaks volumes of your mentality. Divide and conquer, tweedle-dum and tweedle-dee. When are you moving to Excremento or Washington where your type of people live?

    @Fred 5:34pm yesterday- The Anchorage quake was in 1964 and the tsunami from that one is what wiped out downtown Crescent City. Twelve people died. http://en.wikipedia.org/wiki/1964_Alaska_earthquake

    @HiFi- We’re overdue for a decent one so are making do with the one we’ve had. Maybe the epicenter of the next 5.6 will be under your house. Who will be the weenie then, I wonder?

    This quake felt different to me than the others I’ve been through. It felt more “swimming” and not the usual bump and grind. Maybe it was related to those metal boxes showing up along the Oregon Coast?

  50. tra
    February 14, 2012 at 5:03 pm

    It felt different than some other quakes, because was generated in a different way than some of those quakes…but not in a particularly scary way:

    “Humboldt State University geology professor Lori Dengler said the quake was a fairly typical one for inland Humboldt County.

    ”This is a type of earthquake we’ve had before and we’ll have again,” she said. “They’re unlikely to do much in the way of damage and probably don’t tend to get much bigger than what we had today…

    …The Cascadia Subduction Zone produces three types of earthquakes, the biggest being a rupture of the locked-interface subduction zone, which created a magnitude 9 earthquake in 1700, Dengler said. The subduction zone is also capable of producing strike-slip earthquakes offshore, similar to the magnitude 6.5 earthquake that shook the North Coast in January 2010.

    The subduction zone also produces quakes like Monday’s “down-slab” event, which are not as common as their offshore counterparts, Dengler said. These earthquakes generally occur on faults that can’t be seen from the earth’s surface, she said.”

    For more info on how this “down-slab” type quake is generated, see the Times-Standard article:

    http://www.times-standard.com/localnews/ci_19960180

    (Nothing in the Times-Standard article about strange metal boxes showing up along the Oregon coast, though).
