Is There a Connection Between the Injection Wells and the Recent Quake?

Four point seven scared the goodness out of me i was at my house, and i could actually see my floor making waves. That's the largest earthquake we've had in arkansas an 35 years. And it was shortly after that they shut the injection wells down. Two companies have stopped using injection wells near the side of the recent swarm of earthquakes. Could be simply part of the natural ebb and flow, or it could be in relation to the fact that they actually shut the wells down.
