Earthquakes in Mexico — September 2026

50 earthquakes were recorded in Mexico during September 2026, an average of 1.7 per day.

20 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 5.6 earthquake near Puerto Madero, Mexico on 02 September 2026 at 12:28 UTC. A magnitude 5.6 earthquake radiates roughly 3,788 tons of TNT equivalent in seismic energy.

That is close to the Mexico monthly average of 47 events over the period we cover, and down from the 78 recorded the previous month.

92% of events here are shallow (under 70 km), 8% 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, 17 in the magnitude 1 range, 11 in the magnitude 2 range, 17 in the magnitude 4 range, 3 in the magnitude 5 range.

Activity peaked on 07 September, when 6 events were recorded.

The month's largest events were M5.6 near Puerto Madero, Mexico on 02 September at 10 km; M5.3 near off the coast of Michoacan, Mexico on 14 September at 10 km; M5.3 near Puerto Madero, Mexico on 06 September at 10 km.

That is close to the 47 events Mexico averages per month across the 23 months on record.
