Earthquakes in Mexico — August 2026

62 earthquakes were recorded in Mexico during August 2026, an average of 2.0 per day.

19 reached magnitude 4 or above and 3 reached magnitude 5 or above. The average focal depth was 15 km.

The month's largest event in Mexico was a magnitude 5.7 earthquake near Puerto Madero, Mexico on 18 August 2026 at 05:02 UTC. A magnitude 5.7 earthquake radiates roughly 5,351 tons of TNT equivalent in seismic energy.

That is well above the Mexico monthly average of 47 events over the period we cover — an unusually active month, and down from the 142 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 4 in the magnitude 0 range, 28 in the magnitude 1 range, 9 in the magnitude 2 range, 2 in the magnitude 3 range, 16 in the magnitude 4 range, 3 in the magnitude 5 range.

Activity peaked on 02 August, when 11 events were recorded.

The month's largest events were M5.7 near Puerto Madero, Mexico on 18 August at 10 km; M5.2 near Puerto Madero, Mexico on 16 August at 35 km; M5.1 near Bahía de Lobos, Mexico on 02 August at 10 km.

That is 31% above the 47 events Mexico averages per month across the 21 months on record.
