Earthquakes in Mexico — March 2025

27 earthquakes were recorded in Mexico during March 2025, an average of 0.9 per day.

4 reached magnitude 4 or above and 3 reached magnitude 5 or above. The average focal depth was 18 km.

The month's largest event in Mexico was a magnitude 5.6 earthquake near San Miguel Achiutla, Mexico on 15 March 2025 at 03:19 UTC. A magnitude 5.6 earthquake radiates roughly 3,788 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 37 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 8 in the magnitude 1 range, 10 in the magnitude 2 range, 5 in the magnitude 3 range, 1 in the magnitude 4 range, 3 in the magnitude 5 range.

Activity peaked on 05 March, when 2 events were recorded.

The month's largest events were M5.6 near San Miguel Achiutla, Mexico on 15 March at 64 km; M5.5 near San Mateo del Mar, Mexico on 05 March at 47 km; M5.0 near Colonia Juárez, Mexico on 02 March at 53 km.

That is 43% below the 47 events Mexico averages per month across the 21 months on record.
