Earthquakes in Argentina — March 2025

13 earthquakes were recorded in Argentina during March 2025, an average of 0.4 per day.

13 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 210 km.

The month's largest event in Argentina was a magnitude 4.9 earthquake near San Antonio de los Cobres, Argentina on 07 March 2025 at 04:27 UTC. A magnitude 4.9 earthquake radiates roughly 338 tons of TNT equivalent in seismic energy.

That is below the Argentina monthly average of 18 events over the period we cover — a comparatively quiet month, and up from the 11 recorded the previous month.

8% of events here are shallow (under 70 km), 85% intermediate (70–300 km) and 8% 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 13 in the magnitude 4 range.

Activity peaked on 30 March, when 2 events were recorded.

The month's largest events were M4.9 near San Antonio de los Cobres, Argentina on 07 March at 191 km; M4.8 near Vinchina, Argentina on 18 March at 92 km; M4.8 near San Antonio de los Cobres, Argentina on 10 March at 193 km.

That is 28% below the 18 events Argentina averages per month across the 21 months on record.
