Earthquakes in Argentina — November 2025

21 earthquakes were recorded in Argentina during November 2025, an average of 0.7 per day.

21 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 202 km.

The month's largest event in Argentina was a magnitude 4.9 earthquake near Chos Malal, Argentina on 10 November 2025 at 09:10 UTC. A magnitude 4.9 earthquake radiates roughly 338 tons of TNT equivalent in seismic energy.

That is close to the Argentina monthly average of 18 events over the period we cover, and up from the 11 recorded the previous month.

0% of events here are shallow (under 70 km), 95% intermediate (70–300 km) and 5% 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 21 in the magnitude 4 range.

Activity peaked on 24 November, when 3 events were recorded.

The month's largest events were M4.9 near Chos Malal, Argentina on 10 November at 212 km; M4.9 near Abra Pampa, Argentina on 28 November at 222 km; M4.9 near San Antonio de los Cobres, Argentina on 18 November at 179 km.

That is 16% above the 18 events Argentina averages per month across the 21 months on record.
