Recent earthquakes in Fox Creek, Alberta have sparked a global debate on the risks and environmental impacts of hydraulic fracturing (for short, 'fracking') for enhanced oil and gas recovery. Three earthquakes in this previously quiescent region exceeded a moment magnitude of 4.0, which rank among the largest fracking-induced events in the world. Injection operations were temporarily suspended in June 2015, in compliance with the first Traffic-light subsurface regulation in Canada. The lack of seismic receivers in the vicinity of shale gas stimulation wells, however, greatly hamper the detection and location of earthquakes, especially the magnitude 2-4 events that are crucial to the evaluation of subsurface fault(s), criticality and stress conditions.

最近阿尔伯塔省福克斯溪发生的地震引发了全球关于提高石油和天然气采收率的水力压裂（简称“水力压裂”）的风险和环境影响的辩论。 这个先前平静的地区发生了三起震级超过 4.0 级的地震，属于世界上最大的水力压裂引发的事件之一。 2015 年 6 月，根据加拿大第一个交通灯地下法规，注水作业暂停。 然而，页岩气增产井附近缺乏地震接收器，极大地妨碍了地震的检测和定位，特别是对于评估地下断层、临界性和应力条件至关重要的 2-4 级地震。
