Probably not.  The release of energy in small amounts, by whatever 
cause, probably is good as it relieves stress.  Remember, there were 
some BIG earthquakes in the New Madrid area between December 1811 and 
February 1812.
If petroleum exploration and extraction is the cause of these seismic 
events, it is probably doing a great service to the area. by relieving 
stress in small increments.

      Am I the only one concerned by the oil company drilling? Isn't
      this more serious than surface coal mine blasting?
