Earthquakes in Mexico — October 2025

32 earthquakes were recorded in Mexico during October 2025, 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 16 km.

The month's largest event in Mexico was a magnitude 4.8 earthquake near Niños Héroes, Mexico on 12 October 2025 at 02:26 UTC. A magnitude 4.8 earthquake radiates roughly 239 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 75 recorded the previous month.

94% of events here are shallow (under 70 km), 6% 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 10 in the magnitude 1 range, 12 in the magnitude 2 range, 7 in the magnitude 3 range, 3 in the magnitude 4 range.

Activity peaked on 21 October, when 4 events were recorded.

1 event(s) this month carry a USGS link to NOAA tsunami information; the flag does not indicate whether a tsunami occurred.

The month's largest events were M4.8 near Niños Héroes, Mexico on 12 October at 159 km; M4.4 near La Esperanza (El Zapotal), Mexico on 26 October at 87 km; M4.3 near Maneadero, B.C., Mexico on 06 October at 14 km.

That is 32% below the 47 events Mexico averages per month across the 21 months on record.
