Earthquakes in Canada — October 2025

23 earthquakes were recorded in Canada during October 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 3 km.

The month's largest event in Canada was a magnitude 3.0 earthquake near Lively, Canada on 20 October 2025 at 00:46 UTC. A magnitude 3.0 earthquake radiates roughly 477 kg of TNT equivalent in seismic energy.

That is close to the Canada monthly average of 21 events over the period we cover, and down from the 34 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 1 in the magnitude 0 range, 11 in the magnitude 1 range, 10 in the magnitude 2 range, 1 in the magnitude 3 range.

Activity peaked on 31 October, when 3 events were recorded.

The month's largest events were M3.0 near Lively, Canada on 20 October at 10 km; M2.9 near North Saanich, Canada on 21 October at 12 km; M2.3 near Princeton, Canada on 04 October at -0 km.

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