Fault cavity found near Marianna, Arkansas indicate region can produce 7+ magnitude earthquakes

October 22, 2011MARIANNA, AR. – Researchers have found new evidence of earthquakes in the Mid-South. They say the quakes could be the result of a new fault line, a little sister, or big sister, of the New Madrid. “It’s opened up to ancient history down here,” geophysicist Rob Williams tells abc24.com as he looks down into a pit made to study evidence of earthquakes in Marianna, Arkansas. “We’re looking back 4,000 to 10,000 years down in this pit,” he says. The pit may seem like a simple hole in the ground, but to Williams it’s much more. “What this shows,” he says, “is that we’ve had at least two large earthquakes in the last 10,000 years about as big as the New Madrid earthquakes of 1811 and 1812.” Williams tells abc24.com those earthquakes were huge. “Magnitude seven plus,” he says, “but probably less than an 8.” Williams says it isn’t a fault line in Marianna, but rather the effects of strong ground shaking. He say’s when the ground shakes cracks will open up and sand that’s under pressure from all the shaking water wants to escape and that sand and water will flow onto the ground surface. Scientists are in the area to study earthquakes in the region.ABC24
2009 discovery: A previously unknown fault in eastern Arkansas could trigger a magnitude 7 earthquake with an epicenter near a major natural gas pipeline, a scientist said Wednesday. Haydar Al-Shukri, the director of the Arkansas Earthquake Center at the University of Arkansas at Little Rock, said the fault is separate from the New Madrid fault responsible for a series of quakes in 1811-12 that caused the Mississippi River to flow backward. Acres of cotton fields cover the fault west of Marianna, about 100 miles east of Little Rock, but stretches of fine sand mixed with fertile soil gave away the fault’s location, Al-Shukri said. Liquefied sand bubbled up through cracks in the earth, while ground radar and digs showed vents that let the sand reach the surface, he said. The fault, likely created in the last 5,000 years, sparked at least one magnitude 7 earthquake in its history. Such temblors cause massive destruction in their wake. “This is a very, very dangerous (area) at risk of earthquake,” Al-Shukri said. “When you talk about (magnitude) 7 and plus, this is going to be a major disaster.” Al-Shukri did not identify a time frame for the potential earthquake. Such a quake would affect Little Rock and neighboring states such as Tennessee and Mississippi, Al-Shukri said. The researcher has said a gas pipeline crossed the newly discovered fault. –Community

    Is it possible the swarm of Earthquakes in that area a few months ago were related to this fault or were they in a different area? I know the was a lot of speculation that they were being caused by underground drilling and the waste water being shot back into the Earth under high pressure at the time and they seem to have stopped since they quit doing that.

    I guess this tells us, that this area of the Midwest, is not as ‘geologically stable’ as once thought. ❗

  3. Wow. A mag 7 quake would definitely be felt up here in Ohio. This would surely be disastrous with all of the major cities in it’s path. The building codes for the South and Midwest are not built for earthquakes. Praying it doesn’t go.



  4. On the USGS site, Arkansas has been showing mag 1.8 up to 3.8 over the past couple of weeks. I used to live in Memphis, Tn during the 70’s, I remember the earthquake we had in 76, I believe it was a 5.0. I admire people that live in California, I don’t believe I could, that earthquake I felt in Memphis “scared” me more than anything I can remember. I remember deciding then I wanted to move away, as I learned more information concerning the New Madrid fault.
    I currently live outside of Nashville, where we endured the flood of 2010.
    I found TEP protocol about 6 mths ago, have the book, ordered one for my parents.
    At times it seems everything is coming to a climax, then it calms down.
    Blessing to All…

      Pamela Senter: Dennis E. Here: I agree. Sometimes it seems like someone starts a motor, rev’s it up real loud and then let’s it run normally, then rev’s it up again.
      I think that is where the major cause anxiety and panic attacks among the populace.

    HOLY MOLY! This is the EXACT location I saw in my vision last year. I saw the ground buckling in like it was being pulled from underneath. According to my vision, this fault is also connected to the faults in the Gulf of Mexico, and the conditions there will cause this one to react. I am blown away by this.

    Yes, Nick is was the Fracking. The word just escaped me at the time I left the comment. I would still like to know more about if the areas experiencing the Quakes before are close to this newly discovered fault line. I didn’t know they had been still having small Quakes there. I’ve gotten slack on checking the daily Earthquake site daily lately. I guess I better get back on the ball. Thanks for the heads up Pamela.
