Earthquakes in Argentina — May 2026

18 earthquakes were recorded in Argentina during May 2026, an average of 0.6 per day.

17 reached magnitude 4 or above and 1 reached magnitude 5 or above. The average focal depth was 170 km.

The month's largest event in Argentina was a magnitude 5.0 earthquake near Chamical, Argentina on 02 May 2026 at 05:04 UTC. A magnitude 5.0 earthquake radiates roughly 477 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 12 recorded the previous month.

17% of events here are shallow (under 70 km), 83% 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 1 in the magnitude 3 range, 16 in the magnitude 4 range, 1 in the magnitude 5 range.

Activity peaked on 16 May, when 4 events were recorded.

The month's largest events were M5.0 near Chamical, Argentina on 02 May at 10 km; M4.8 near San Antonio de los Cobres, Argentina on 08 May at 198 km; M4.7 near El Aguilar, Argentina on 16 May at 245 km.

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