Earthquakes in Argentina — August 2025

18 earthquakes were recorded in Argentina during August 2025, an average of 0.6 per day.

18 reached magnitude 4 or above and 2 reached magnitude 5 or above. The average focal depth was 112 km.

The month's largest event in Argentina was a magnitude 5.7 earthquake near Ushuaia, Argentina on 19 August 2025 at 06:08 UTC. A magnitude 5.7 earthquake radiates roughly 5,351 tons of TNT equivalent in seismic energy.

That is close to the Argentina monthly average of 18 events over the period we cover, and level with the 18 recorded the previous month.

39% of events here are shallow (under 70 km), 61% intermediate (70–300 km) and 0% deep-focus (over 300 km). A substantial share of intermediate-depth events points to a subducting slab beneath the region rather than purely crustal faulting.

By band, the catalogue holds 16 in the magnitude 4 range, 2 in the magnitude 5 range.

Activity peaked on 22 August, when 3 events were recorded.

The month's largest events were M5.7 near Ushuaia, Argentina on 19 August at 10 km; M5.0 near Abra Pampa, Argentina on 17 August at 265 km; M4.9 near San Agustín de Valle Fértil, Argentina on 22 August at 28 km.

That is close to the 18 events Argentina averages per month across the 21 months on record.
