Earthquakes in Argentina — August 2026

13 earthquakes were recorded in Argentina during August 2026, an average of 0.4 per day.

The month's largest event in Argentina was a magnitude 4.7 earthquake near San Antonio de los Cobres, Argentina on 20 August 2026 at 03:09 UTC. A magnitude 4.7 earthquake radiates roughly 169 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 down from the 16 recorded the previous month.

8% of events here are shallow (under 70 km), 92% 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 13 in the magnitude 4 range.

Activity peaked on 02 August, when 3 events were recorded.

The month's largest events were M4.7 near San Antonio de los Cobres, Argentina on 20 August at 167 km; M4.6 near San Antonio de los Cobres, Argentina on 08 August at 164 km; M4.6 near San Antonio de los Cobres, Argentina on 03 August at 183 km.

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