Why The Earthquakes

Since the begining of the injection of salt water into the Arkansas shale area there has been over 800 tremors, the largest being a 4.7 in the Greenbrier area. There is mixed emotion on the cause of these tremors. Scientist's are not definite on the cause but when limited injections and pressure were reduced the frequency of the quakes diminished. That has led scientist and area residence to speculate that the injections caused the tremors and feel more research is needed before increased drilling occurs.
