America: Fracking - hundreds of earthquakes a year in Oklahoma

According to state-conducted research, widespread fracking and fracking wastewater injection have transformed the state of Oklahoma from a place that had an average of two tiny earthquakes a year to the most seismically active area in the United States. In fact, the massive surge in fracking-related quakes has even alerted Oklahoma Geological Survey (OGS) as to the existence of many formerly stable and dormant underground faults that it didn’t previously know existed. EcoWatch reported, ‘Oklahoma was never big earthquake country but in the last six years their numbers have surged, going from an average of two a year over 3.0 magnitude to 585 last year, surpassing California as the US’s most seismically active state.’ The state of Oklahoma has even set up its own earthquake website, whereon it states this rise in seismic events has the attention of scientists, citizens, policymakers, media and industry. After 35 fracking earthquakes rocked Oklahoma in the first week of July the state has had more pressure than ever on it to put a damper on the cause before things get out of hand.
