Yeah, we felt it too

There was an earthquake in Fort Worth tonight.  Well, we don't know where it was centered but we have reports coming in from North Fort Worth of a lot of shaking going on. And Google has lit up like a Christmas tree.  And, we felt the earth shaking.

Last night there was an earthquake in Oklahoma City.  Tonight an earthquake in Fort Worth.  What does Fort Worth and Oklahoma City have in common? Aside from gas drillers? 

Just saying.  And shaking.  On Saturday night in Texas.

Incoming update - 
Word is it was a 5.6 earthquake in Sparks, Oklahoma.  Like they say, what happens in Oklahoma, doesn't stay in Oklahoma...

What happens to water mains and gas pipelines when the ground moves?
