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 close to the Argentina monthly average of 17 events over the period we cover, and down from the 16 recorded the previous month.

7% of events here are shallow (under 70 km), 93% 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 14 in the magnitude 4 range.
