Earthquakes in Canada — September 2026

29 earthquakes were recorded in Canada during September 2026, an average of 1.0 per day.

6 reached magnitude 4 or above and 4 reached magnitude 5 or above. The average focal depth was 4 km.

The month's largest event in Canada was a magnitude 5.5 earthquake near Port McNeill, Canada on 28 September 2026 at 04:41 UTC. A magnitude 5.5 earthquake radiates roughly 2,682 tons of TNT equivalent in seismic energy.

That is well above the Canada monthly average of 22 events over the period we cover — an unusually active month, and up from the 25 recorded the previous month.

100% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 0% deep-focus (over 300 km). Almost everything here is crustal. That is characteristic of transform faulting or continental deformation rather than subduction — and it means shaking at the surface is strong for the magnitudes involved.

By band, the catalogue holds 3 in the magnitude 0 range, 14 in the magnitude 1 range, 5 in the magnitude 2 range, 1 in the magnitude 3 range, 2 in the magnitude 4 range, 4 in the magnitude 5 range.

Activity peaked on 28 September, when 7 events were recorded.

4 event(s) this month carry a USGS link to NOAA tsunami information; the flag does not indicate whether a tsunami occurred.

The month's largest events were M5.5 near Port McNeill, Canada on 28 September at 11 km; M5.4 near Port McNeill, Canada on 28 September at 10 km; M5.2 near Port McNeill, Canada on 28 September at 10 km.

That is 33% above the 22 events Canada averages per month across the 23 months on record.
