Mitigating hydraulic fracturing-induced seismicity (HF-IS) poses a challenge for shale gas
companies and regulators alike. The use of Traffic Light Schemes (TLSs) is the most …

Hydraulic fracturing (HF) at Preston New Road (PNR), Lancashire, United Kingdom, in
August 2019, induced a number of felt earthquakes. The largest event (⁠ ML 2.9) occurred …

We compare current and historic seismicity rates in six States in the USA and three
Provinces in Canada to past and present hydrocarbon production. All States/Provinces are …

Identifying the causal factors behind elevated seismicity rates in areas with multiple ongoing
oil and gas activities has always been a challenging issue that is lacking a homogeneous …

A key element in the assessment of seismic hazard is estimation of the maximum possible
earthquake magnitude, Mmax. A great deal of effort has been invested in developing …

A rapid increase of injection‐induced earthquakes (IIE) is often linked to a higher level of
seismic hazard. In this study, we compare the geodetically defined moment rate to seismicity …

We investigate the physical processes that generate seismicity during hydraulic fracturing.
Fluid processes (increases in pore pressure and poroelastic stress) are often considered to …

We examine differences in the occurrence rates of hydraulic fracturing-induced seismicity
(HF-IS) between different shale plays in North America. While previous studies have …

Injection of large volumes of carbon dioxide (CO 2) for the purposes of greenhouse-gas
emissions reduction has the potential to induce earthquakes. Operators of proposed projects …

To date, hydraulic fracturing for shale gas extraction has been used at three wells in the UK.
In each case, the resulting microseismicity exceeded the UK's red-light threshold of …
