4.6 magnitude earthquake shakes upper Washington

November 18, 2011WENATCHEE, Wash. – North central Washington was shaken by a 4.6 magnitude quake early Friday that awakened many residents but caused little or no damage. The Pacific Northwest Seismic Network reports it occurred at 5:09 a.m. Friday and was centered seven miles northwest of Omak, and 8 miles northwest of Okanogan. KPQ in Wenatchee reports callers say it was felt in Leavenworth, where it was described as a rolling motion, and in Twisp where it was strong enough to shake items off a shelf. Residents of the area tell KOMO News that the quake was strong enough to wake them up. “We are in Twisp, and the shaking was enough to wake us up and was very frightening,” said one woman. Another woman, who lives on the north shore of Lake Chelan, wrote, “My husband and I were sleeping and the bed started shaking, which woke us up around 5:10 a.m. This lasted for about 15 seconds. Just a bunch of shaking, the headboard was going crazy. –KVAL

    Do you think this is going to do anything to wake up the volcanoes there?

    This one definitely caught my attention when I saw it this morning. So I decided to see what the earthquake history was for the State of Washington.

    It appears that, although not a common occurance, Washington does have a history of earthquakes. The strongest one I could find was a mag 7.3 on June 23, 1946. It also seems that a tsunami was caused by a nearby landslide.

    What really amazes me is all the seismic activity happening in and around the United States lately. Alvin, have you done any research on earthquake cycles in the U.S.? I’ve been thinking about looking into it during my “spare” time, just to see if this is “normal” or something we should be concerned about.

    Unusual place for an earthquake though. I think that’s more the story – earthquakes happening where they don’t usually. 4.6 ties the biggest EQ within 100 miles of Omak in the last 35 years – the other one was a 4.6 in 1997.

    I certainly agree that these earthquakes in bizarre locations mean something (whatever that may be.) I live in New England (USA) and in 40 years never felt an earthquake until this past August. It was nothing major but enough that we all felt the shake. Not to mention our weird weather. I realize of course that this is New England and out weather is bizarre anyway, but, we had a Nor’easter on Halloween (2 feet of snow in 12 hours) and then it was 60 degrees until yesterday. Again, in 40 years I have never, never experienced weather like this.

    Tonight I’ve got an “earthquake headache” bigtime. I think all these (now the norm) 4.5 + are swarming for a big shaker very, very soon.
