Abstract
Summary
It is well established that hydraulic fracturing can cause reactivation of pre-existing subsurface geological structures resulting in induced seismicity. In response, various jurisdictions have imposed mitigating regulations, primarily in the form of Traffic Light Schemes, whereby injection is reduced or stopped if seismic events exceed a certain magnitude threshold. The threshold magnitudes vary significantly between jurisdictions: for example, in Alberta the red light is set at M = 4, whereas in the UK the red light is set at M = 0.5, a difference in earthquake moment of over 175,000 times.
