This detail of the Natural Resources Canada/ Earthquakes Canada shows the historical record of earthquakes along the northwest coast of British Columbia. The larger the circle, the greater the magnitude.
Most, not all, the earthquakes took place in the tetonic plate boundaries off the coast in the middle of the Pacfic Ocean, although the map does also show quakes on Haidi Gwaii. However, large quakes can be felt far inland. The magnitude 9.2 Good Friday earthquake in Alaska in 1964 did shake the town of Kitimat.
