Earthquakes and Drilling

I have lived in Boone County the majority of my life and never experienced an earthquake until recently. A short time ago drilling to search for gas wells began about eighty miles south of my home county. Within a short time tremors and even a small quake have been felt where I live. Many may believe that more study needs to be done to determine if there is a correlation between drilling and earthquakes, but I believe the facts are clear. The effects of drilling do trigger earthquakes.
