23 quakes strike central Arkansas in 36 hours

The Earth is shaking in central Arkansas.

Almost two dozen earthquakes of magnitude 2.3 or greater have struck the region since midnight Wednesday, the U.S. Geological Survey reports.

The largest of the temblors, at 4.3 magnitude, hit at 2:13 a.m. Friday. It followed a 4.0-magnitude event at 11 p.m. Thursday.

No damage has been reported from any of the quakes, all centered near the town of Greenbrier in Faulkner County, CNN affiliate KARK reports. Residents reported hearing a boom at the time of Friday morning's quake, KARK reported.

The earthquake swarm is reminiscent of a swarm that hit the area last fall. More than 500 were recorded in less than a month.

      All the natural gas test drilling that has been going on. The drilling was mentioned in the dead bird articles.

      I really doubt it was because of the "natural gas drills", this drills don't cause more than 500 quakes in less than a month. If you people didn't know, this use to be a very active geological zone. The 1812 New Madrid Earthquake of magnitude 8.0 is the best example of the geological activity that remains in the area of Missouri, Arkansas, Mississippi, Kentucky, Illinois, and Texas. If we go further back to prehistoric eras, Mount Jackson was the main example of geological-vulcanology activity in this area, the volcano is now extinct, buried beneath Jackson, Mississippi. Other prehistoric geological features in area are the Taum Sauk Caldera in Missouri and Mount Pilot Knob in Texas, all these extinct now but they are now reminders that this area of the US will continue to be geologically active.

      No, it's not the birds, it's not the fish, it's not the fracing, it's not the solar flares, it's not even the hosts of The View.
      Look up the New Madrid fault system.
      The New Madrid Fault, also called the New Madrid seismic zone, is actually a series of faults, or fractures, at a weak spot in the earth’s crust called the Reelfoot Rift. It lies deep in the earth and cannot be seen from the surface. The fault line runs roughly 150 miles from Arkansas into Missouri and Illinois. In 1811–1812, it was responsible for the most violent series of earthquakes in the history of the continental United States (though there have been larger individual earthquakes). Scientists predict that another large earthquake is due which could inflict great damage to Arkansas as well as up to half the nation.

      Agree Wzrd, the 1812 New Madrid Earthquake was the US' most intense earthquake in recorded history. This event was unique because the quake was an intense intraplate-earthquake, it was felt strongly over roughly 50,000 square miles, and moderately across nearly 1 million square miles.

      GREENBRIER, AR EARTHQUAKE SWARM

      This earthquake is part of a swarm of earthquakes that began on Tuesday February 15, 2011 and is continuing. This area is slightly south of and most likely related to similar activity (known as the Guy earthquake swarm) of hundreds of small earthquakes near Guy, Arkansas from August 2010 to present. Central Arkansas has a history of earthquake activity with a swarm of thousands of earthquakes smaller than magnitude 4.5 to 4.7 in the early 1980s and another swarm in 2001 (known as the Enola earthquake swarms). The Center for Earthquake Research and Information (CERI) at the University of Memphis and the Arkansas Geological Survey (AGS) have deployed a local seismic array in the Greenbrier-Enola, Arkansas, area to augment regional seismic stations to carefully monitor this situation. USGS scientists have been working with their AGS and CERI colleagues. (earthquake.usgs.gov/earthquakes/recenteqsus/Quakes/nm1182.php#details)

      San Andreas is ok for now and it has nothing to do with Arkansas or this geological region. Best to keep an eye on Greenbrier, because it could become 'Mount Greenbrier'.

      The San Andreas fault is only one of several in that area. The big one will be where one fault after another triggers the next in line.

      Fracking is only done in old wells. Once the pressure had been dissipated and a pump jack no longer brings the product up they use Fracking. It has been around at least 20 years and, to date, has not been involved in any quakes or bird poisonings. I am not defending the petroleum industry as I loathe everything about it. However, it is better to focus on the actual problems. I live where the 2nd largest reserves in the world are, Alberta Canada. Tar Sands. Now that is a big problem.

      Greenbrier is southwest of the southern mapped tip of the New Madrid seismic zone. However, this may very well be directly related to NMSZ and could be a precursor to a major event sometime in the future. Any seismologists or vulcanologists care to share an opinion?

    From AOL news: Some experts said natural gas exploration, which is extensive in the region, may be triggering the seismic surge, but they noted that no direct correlation between the drilling and the earthquakes has been proven.

    Arkansas is on the New Madrid fault line. The last great earthquake in that area was in 1811-1812 when the Mississippi ran backward. That was a 7 point quake. A 7 point quake in that area today could devastate Memphis and surrounding areas.

      The New Madrid fault would/does affect central Ark. but it is more to the east, closer to Memphis and extending north to St. Louis. Why has the more epi-central area been stable? I suspect the problem is the energy bilionaires fracking for even more money–they can't get enough of it. If our country had proper oversight/regulation over the projects of these greedy billionaires, we might have an answer. But as another poster noted, that's probably not going to happen.

      No, the magnitude of the 1811-12 quakes was much higher than 7. The quake awoke the President in the White House and rang bells in Philadelphia. The Richter scale was not in use back then, but some estimates place the quake at somewhere between 8 and 10. And yes, siesmic activity may well have resulted in the release of toxic gases which killed the fish in Northern AK and disoriented the birds which died en masse in the same region. When I first read those headlines, that was my first thought. That area has been very seismically active for a long time now, with numerous small quakes daily around the region. It does seem that the fault is "heating up". And the seismic activity of the region pre-dates the drilling for gas, which is a (relatively) new event, so I don't think that the drilling can fully account for it.

      Take it from someone that grew up in the state, these quakes aren't causing any concern to the locals. Arkansas has the New Madrid Fault in the northeast and an extinct volcano in the southwest. The state is more geologically active than most know, so it isn't a surprise. Either the New Madrid is getting ready to move or the volcanic Ouachita region has decided to do something out of the ordinary.

    I am from Ar, and with all the dead birds, fish, and unusual weather a large earthquake does not surprise me. However, there have always been earthquakes due to the location of the New Madrid fault in AR. I am more worried about how poorly our local governments and emergency aid will handle the situation if something does happen.
