Earthquakes in Argentina — July 2025

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

18 reached magnitude 4 or above and 3 reached magnitude 5 or above. The average focal depth was 201 km.

The month's largest event in Argentina was a magnitude 5.6 earthquake near Ushuaia, Argentina on 04 July 2025 at 15:47 UTC. A magnitude 5.6 earthquake radiates roughly 3,788 tons of TNT equivalent in seismic energy.

That is close to the Argentina monthly average of 18 events over the period we cover, and down from the 21 recorded the previous month.

17% of events here are shallow (under 70 km), 72% intermediate (70–300 km) and 11% deep-focus (over 300 km). That proportion of deep-focus events is the signature of a subduction zone: only a cold slab descending into the mantle stays brittle enough to rupture at those depths.

By band, the catalogue holds 15 in the magnitude 4 range, 3 in the magnitude 5 range.

Activity peaked on 18 July, when 3 events were recorded.

The month's largest events were M5.6 near Ushuaia, Argentina on 04 July at 10 km; M5.1 near El Hoyo, Argentina on 09 July at 575 km; M5.0 near San Antonio de los Cobres, Argentina on 13 July at 190 km.

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