Résumé(disponible en anglais seulement)
The west coast of Canada is the most seismically active region in the country, recording several thousand earthquakes each year. Most seismicity is concentrated along the Queen Charlotte Fault (QCF) to the north and throughout the northern end of the Cascadia Subduction Zone to the south. In 2008, the location of a key station for establishing the east-west distribution of earthquakes along the QCF was found to be in error by nearly 7.5 km. The relocation of events which relied on this station has altered the distribution of locations and associated stress release in the region, and potentially affected the calculated seismic hazard. We present observations on the effect of these relocations.
