Drilling verses Earthquakes

Even though scientist cannot come to a consensus about the coincidence of drilling for natural gas and the frequencies of earthquakes. My conclusion is drawn from a newspaper report of earthqakes in cities who have never had earthquakes. "In 2009, the small town of Ceburne, Texas, experienced the first recorded earthquake in this Texas town's 140 year history, quickly followed by another four shortly afterwards. Was natural gas drilling--which gegan in earnest in 2002 and brought great properity to Cleburne and other towns across north Texas--causing the quakes?" (FoxNews.com) Another incident of earthquakes happened in West Virginia after drilling for natural gas.
