Earthquake Warning

earthquake oklahoma   The graph (from USGS) shows earthquakes of magnitude 3.0 and greater in Oklahoma since 1978.  Click on the image to enlarge.  As you can see, the number of earthquakes in Oklahoma 3.0 or greater was relatively small (less than 2 a year) until 2009.  We’re not halfway thru 2014 and you can see we’re already had nearly 150 quakes.   Since 2009, Oklahoma has had  20 magnitude 4.0 to 4.8 quakes, plus the largest earthquake in Oklahoma’s history – a magnitude 5.6 earthquake that occurred near the town of Prague on Nov. 5, 2011.  Here’s a map of earthquakes in Oklahoma – most north and east of Oklahoma City.  A likely contributing factor to the increase in earthquakes is wastewater injected into deep geologic formations.  You can learn more here.

  1. Just one word! FRACKING!!

    WOW, Oklahoma is the last place you would think would have earthquakes.

    FRICKIN” FRACKIN” dont care what you call it. Oklahoma is geographic the center of the U.S. Weird.

    smh

    If we continue on our current path, Michigan will also be injecting larger quantities of contaminated, never-to-be-”pure”-again wastewater to fill space vacated by gas drilling. I’d much rather have my energy investments (subsidies) support wind, solar, geothermal, and conservation rather than gas, oil and coal.

    My sister lives in Oklahoma City and besides the tornado threats all those earthquakes has cracked her foundation and brick siding. She’s had two EF5 tornadoes go by her house and its amazing when I go down and visit. One place you have a neighborhood and then you turn and all you see is foundations, but its really interesting to see the rebuilding going on.

    While I agree that there appears to be a clear connection to fracking in OK – there are tons of disposal wells all over (including Michigan) and I don’t think anywhere else consistently shows up on the USGS earthquake charts like this area in OK does? And wells alone shouldn’t produce a 5+M level quake? So there’s clearly seismic activity in the OK area, and maybe the wells are just “lubing” the ground movement…..

    I’m guessing the magma is closer to the surface there, than anyone thought?

      GunLakeDeb, your guess is as good as mine or anyones. They’ve been pullin oil, gas and other stuff out of wells here in MIchigan for years and not much shakin goin on here. Salt brine wells in Manistee and Midland areas, oil and gas in the north LP…nothing here to speak of.
      But then again blame it on sumthin I guess….

    2. Resourceful Nana says:

      I believe there are places in Ohio and Pennsylvania that have had seismic activity that could be related to fracking.

    I’m thinking it must be global warming. ;-)

    As a race, we’re doing a great job of using our bed as a bathroom, euphemistically speaking. In the past, we could pull up and move, but there’s no where else to go. When will we learn. History suggests, never.

      Air and water are cleaner now than they were 40 years ago, 70 years ago, 100 years ago.

        Not sure where you get your statistics for that statement. Toxic chemicals and fertilizer run-off (along with algae blooms and excessive weed growth) are abundant in our lakes and streams–not there when I was a kid; we’re advised not to eat fish very often due to mercury (waste product of burning fossil fuels), and rural residents drill deeper wells to avoid the nitrates that have leached into groundwater. We shouldn’t be contaminating fresh water to pump into fracking holes! Only 1% of the water on earth is available as fresh water to maintain life. (2% is locked up in polar ice caps.) The way we use and abuse it, we may one day find it “extinct”-like the passenger pigeon.
