Earthquakes in Mexico — December 2025

34 earthquakes were recorded in Mexico during December 2025, an average of 1.1 per day.

9 reached magnitude 4 or above and 3 reached magnitude 5 or above. The average focal depth was 21 km.

The month's largest event in Mexico was a magnitude 5.5 earthquake near José María Morelos, Mexico on 05 December 2025 at 19:33 UTC. A magnitude 5.5 earthquake radiates roughly 2,682 tons of TNT equivalent in seismic energy.

That is below the Mexico monthly average of 47 events over the period we cover — a comparatively quiet month, and down from the 54 recorded the previous month.

97% of events here are shallow (under 70 km), 3% 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 15 in the magnitude 1 range, 9 in the magnitude 2 range, 1 in the magnitude 3 range, 6 in the magnitude 4 range, 3 in the magnitude 5 range.

Activity peaked on 27 December, when 4 events were recorded.

The month's largest events were M5.5 near José María Morelos, Mexico on 05 December at 8 km; M5.3 near El Morro, Mexico on 04 December at 63 km; M5.2 near Puerto Madero, Mexico on 22 December at 35 km.

That is 28% below the 47 events Mexico averages per month across the 21 months on record.
