Earthquakes in Canada — December 2025

15 earthquakes were recorded in Canada during December 2025, an average of 0.5 per day.

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

The month's largest event in Canada was a magnitude 3.0 earthquake near Saint-Pascal, Canada on 18 December 2025 at 03:19 UTC. A magnitude 3.0 earthquake radiates roughly 477 kg of TNT equivalent in seismic energy.

That is below the Canada monthly average of 21 events over the period we cover — a comparatively quiet month, and down from the 27 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 2 in the magnitude 0 range, 7 in the magnitude 1 range, 5 in the magnitude 2 range, 1 in the magnitude 3 range.

Activity peaked on 04 December, when 3 events were recorded.

The month's largest events were M3.0 near Saint-Pascal, Canada on 18 December at 19 km; M2.2 near Princeton, Canada on 15 December at -0 km; M2.2 near Princeton, Canada on 31 December at -0 km.

That is 29% below the 21 events Canada averages per month across the 21 months on record.
