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.

艾伯塔省福克斯克里克最近发生的地震引发了一场关于水力压裂(简称水力压裂)提高石油和天然气采收率的风险和环境影响的全球辩论。在这个此前平静的地区，有三次地震的瞬间震级超过4.0级，这是世界上由水力压裂引发的最大地震之一。根据加拿大第一个红绿灯地下法规，喷射作业于2015年6月暂时停止。然而，页岩气刺激井附近缺乏地震接收器，大大阻碍了地震的探测和定位，特别是对地下断层(S)、危害性和应力条件的评估至关重要的2-4级地震。
