"To gain a better understanding of induced seismicity in northeast British Columbia and western Alberta, we conducted an intensive analysis of seismic data to locate earthquakes that occurred within the area of 52˚N–61˚N, 126˚W–115˚W for the years of 2014 through 2016. Continuous seismic waveforms from as many as 43 stations operated by various organizations in the region were used in this study. A total of 5478 events were identified and located; but only 4916 solutions were deemed acceptable by our quality criteria. The number of earthquakes in our final catalogue is approximately three times the base level of the Canadian National Seismograph Network catalogue. In this report, we describe in detail our location procedures and how each source parameter (origin time, epicenter, focal depth, and magnitude) is determined"--Abstract, p. 3.
