| Abstract | 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. The earthquake catalogue is summarized in a table, while the phase picking data for individual events are presented in
an ASCII file as a supplement to this report. The total numbers of events in 2014, 2015, and 2016 are 1287, 1575, and 2057, respectively. The overall magnitude of completeness of our catalogue is ML 1.8, an improvement from the value of 2.3 for the
CNSN catalogue. |
| Summary | (Plain Language Summary, not published)
This open file report presents the catalogue of earthquakes that occurred in northeast British Columbia and western Alberta from 1 January 2014 to 31
December 2016. Using data from 43 seismograph stations in western Canada, we have identified and located a total of 4919 seismic events. The number of earthquakes in our final catalogue is approximately three times of the catalogue based on routine
processing of the Canadian National Seismograph Network data. A detailed list of seismic phase picks used in the earthquake location process is given for each event in the Appendix. |
