Earthquakes in Canada — August 2025

21 earthquakes were recorded in Canada during August 2025, an average of 0.7 per day.

0 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 9 km.

The month's largest event in Canada was a magnitude 3.5 earthquake near Inuvik, Canada on 07 August 2025 at 14:14 UTC. A magnitude 3.5 earthquake radiates roughly 2.7 tons of TNT equivalent in seismic energy.

That is close to the Canada monthly average of 21 events over the period we cover, and up from the 13 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 4 in the magnitude 0 range, 7 in the magnitude 1 range, 9 in the magnitude 2 range, 1 in the magnitude 3 range.

Activity peaked on 12 August, when 2 events were recorded.

The month's largest events were M3.5 near Inuvik, Canada on 07 August at 30 km; M2.6 near Princeton, Canada on 10 August at 9 km; M2.3 near Princeton, Canada on 12 August at -0 km.

That is close to the 21 events Canada averages per month across the 21 months on record.
