There has been at least four minor EQ's in the normally
        stable North Central Texas during the last year and half.  Most
        were in or near Cleburne, TX (Johnson County).  Supposedly,
        seismologists fro SMU have investigated and have issued the same
        non-committal statement.  However, fracting IS in high swing in
        this area for the gas wells.
      
 
      
I have seen instruments placed throughout Cleburne, TX
        and Schlumberger trucks around. I can't help but believe that
        some sort of survey is ongoing.

      There are cases of water injection in southern Illinois but I
      never associated any earthquakes with this activity. Is  there
      surface faulting in the Cleburne area? The Guy area has a lot of
      faulting. Some of this faulting runs right into large lakes. In my
      area these surfaces were patched with clay (at least in the dam
      areas) to keep the water from finding pathways through the
      limestone; and I know what oil wells look like in the field but
      the Guy area drilling setup is different and surface ponds that
      are obviously NOT for fish and cattle; they are lined with what
      looks like a blue-gray shale  And a lot of transporting pipelines
      -- clearly labeled.
