Sorry, I cannot address the "surface faulting" question.  I am not that 
versed in geology.  All I know is that according to what I have read, 
Central Texas is relatively stable.  Areas in western Texas historically 
have been geologically active, but that is hundreds of miles away.  I 
understand that there is some faulting in the southern coastal area.

But, here in our area just south of the Dallas/Fort Worth metroplex it is 
basically flat and geologically stable.  There IS a lot of gas exploration 
and wells throughout the general area.  Fracting is in progress.

    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.
