Gentlemen ... these quakes are NOT on the New Madrid system...they may 
be associated with small local faults BUT they are locally close to a 
well drilling site ... take any of the quake sites and Google 
Earth....you will find a well site in the area ... the last Arkansas 
quake occurred about 900ft west of a well drilling apparatus...this 
quake and the one just before it occurred within 800 ft of five well 
site listed by the Arkansas Geological Society.
