During the last 5 years, accelerated oilfield fluid injection has led to a sharp increase in the rate of earthquakes in some parts of North America. In the central United States, most induced seismicity is linked to deep disposal of coproduced wastewater from oil and gas extraction. In contrast, in western Canada most recent cases of induced seismicity are highly correlated in time and space with hydraulic fracturing, during which fluids are injected under high pressure during well completion to induce localized fracturing of rock. Furthermore, it appears that the maximum-observed magnitude of events associated with hydraulic fracturing may exceed the predictions of an often-cited relationship between the volume of injected fluid and the maximum expected magnitude. These findings have far-reaching implications for assessment of inducedseismicity hazards. date: 2016 date_type: published publication: Seismological Research Letters volume: 87 number: 3 publisher: Seismological Society of America id_number: doi: 10.1785/0220150263 issn: 0895-0695 access_IS-EPOS: limited owner: Publisher citation: Atkinson, Gail M. and Eaton, David W. and Ghofrani, Hadi and Walker, Dan and Cheadle, Burns and Schultz, Ryan and Shcherbakov, Robert and Tiampo, Kristy F. and Gu, Jeff and Harrington, Rebecca M. and Liu, Yajing and van der Baan, Mirko and Kao, Honn (2016) Hydraulic Fracturing and Seismicity in the Western Canada Sedimentary Basin.
