One of the concerns I had with fracking was long term geological consequences and these current earthquakes hitting 3.0 on the Richter scale should not just be labeled as a coincidence. I don't want to hear about sinkholes swallowing a whole town twenty years from now. I am not saying that is what will occur, we just don't have enough data to understand all possibilities.
So far there has been reports that the state of Oklahoma is averaging one earthquake a day with a 3.0 or higher Richter scale reading. Additional reports have shown Oklahoma having twice the number of earthquakes California is currently experiencing. Techniques to extract gas and oil is presumed to be the cause. Prior to fracking, Oklahoma had one earthquake above 3.0 per year, not one per day. Additionally, most other locations conducting fracking, have a rise in earthquake activity. Perhaps this all depends on the makeup of the earth's crust in each area. The correlation is hard to ignore, we will not know for sure until scientific studies are done.
First we have to expedite results from scientific research to see if we have proof that fracking activities are increasingly causing earthquakes. If so, then appropriate action must be taken nationwide, not just individual rulings per State.
