6.8 magnitude earthquake strikes off coast of California

Eureaka 6.8 March 10
March 2014 CALIFORNIA - A series of small aftershocks continued to rattle the extreme northern coast of California on Monday, hours after a magnitude 6.8 earthquake shook the town of Eureka and an area extending into Oregon and Nevada with no reports of damage. The main tremor, which struck at about 10:30 p.m. on Sunday, was centered in the Pacific about 50 miles west of Eureka and 10 miles beneath the ocean floor, according to the U.S. Geological Survey. While earthquakes of that size can unleash widespread destruction if they score a direct hit on an urban area, as the 1994 Northridge quake did in Los Angeles, the impact of Sunday’s tremor was largely buffered by its location out at sea, seismologists said. Shaking from the quake was felt most strongly by residents in Eureka, a coastal community about 270 miles north of San Francisco, and the nearby town of Arcata, site of Humboldt State University, the USGS reported. But no tsunami warnings were issued, and the morning watch commander for the Eureka police department, Sergeant Steve Watson, said there were no reports of injuries or damage to property in town. “It lasted around 30 seconds,” Watson said, describing the shock as a side-to-side, rolling motion that lacked the sharp jolts of tremors he had felt in the past. “Nothing fell off our shelves or anything,” he said. Lighter rumbling from the quake extended north into coastal Oregon and eastward as far as Carson City, Nevada, with a handful of reports of light shaking felt as far south as San Francisco.
USGS monitoring showed that the main tremor, initially measured at a 6.9 magnitude but later downgraded, was followed by about 20 aftershocks that continued into the morning hours, said David Oppenheimer, a USGS seismologist. While earthquakes producing noticeable shaking are routine in California, 6.8 magnitude tremors are less commonplace, and potentially dangerous. Quakes of that magnitude are capable of causing substantial damage to some buildings, such as a partial collapse or the shifting of structures off their foundations. Several dozen people were killed and thousands more injured in the Northridge quake, which unlike Sunday’s tremor occurred directly under a densely populated city. Oppenheimer said the quake’s location at sea made all the difference, accounting for why there was so little consequence. “That’s the primary reason,” he said. “The real explanation is that the earthquake was so far offshore.” –Reuters

    Did you see the two quakes 2km S of Lowellville, Ohio? I was walking into my kitchen and thought I was having a vertigo attack. No shaking here, but I definitely felt something.

    It has been very interesting on the west side from Chile,Peru and now here.

    If this is a “pre quake” a big one is coming soon. I’m still watching for the one Owuor was recently shown. Thanks God bless you

    First California, and now Oregon. M5.1 – Off the coast of Oregon. No tsunami threat.

    I used to see a lot of people talking about Eureka.. like it was the site of the next “big one” but that was just talk of course.

    Alvin, I have thought about your comment here quite a bit since I first saw it last week. Now, considering all the strong activity over the last 24 hours or so, I am VERY curious about it. What, in particular is significant about the “next 12 to 25 days”?! I have family up and down the east coast and we are on a small low island off the southeast coast, which has parts that are even below sea level. (Which makes me CRAZY!) I have been following you for a few years now and have all but the newest of your books. Thank you so much!
    Blessings,
    Lisa

    • It’s a duration period for heightened seismic activity across the planet, Lisa. March 15 to April 12 See page 118 of the 7th Protocol why this time of the year appears especially prone to earthquakes. The East Coast has very low seismic hazard risk, and should not be an issue of concern in that regard. Drop me a line, if you have more questions.

      So glad you’re tuning in…
      peace and love
      Alvin
