Earthquakes in Canada — December 2024

31 earthquakes were recorded in Canada during December 2024, an average of 1.0 per day.

3 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 4.4 earthquake near Mayo, Canada on 07 December 2024 at 05:59 UTC. A magnitude 4.4 earthquake radiates roughly 60 tons of TNT equivalent in seismic energy.

That is well above the Canada monthly average of 7 events over the period we cover — an unusually active month, and up from the 7 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, 16 in the magnitude 1 range, 9 in the magnitude 2 range, 2 in the magnitude 3 range, 3 in the magnitude 4 range.

Activity peaked on 01 December, when 3 events were recorded.

The month's largest events were M4.4 near Mayo, Canada on 07 December at 10 km; M4.2 near Mayo, Canada on 18 December at 21 km; M4.2 near Grand-Remous, Canada on 29 December at 10 km.

That is 343% above the 7 events Canada averages per month across the 2 months on record.

This month also holds the strongest earthquake recorded in Canada in our entire catalogue.
