Earthquakes in Argentina — April 2026

12 earthquakes were recorded in Argentina during April 2026, an average of 0.4 per day.

12 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 227 km.

The month's largest event in Argentina was a magnitude 4.9 earthquake near Calingasta, Argentina on 17 April 2026 at 06:19 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 down from the 14 recorded the previous month.

0% of events here are shallow (under 70 km), 92% 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 12 in the magnitude 4 range.

Activity peaked on 17 April, when 4 events were recorded.

The month's largest events were M4.9 near Calingasta, Argentina on 17 April at 112 km; M4.7 near San Antonio de los Cobres, Argentina on 16 April at 193 km; M4.6 near Abra Pampa, Argentina on 01 April at 291 km.

That is 34% below the 18 events Argentina averages per month across the 21 months on record.
