Earthquakes in Argentina — December 2024

22 earthquakes were recorded in Argentina during December 2024, an average of 0.7 per day.

22 reached magnitude 4 or above and 2 reached magnitude 5 or above. The average focal depth was 169 km.

The month's largest event in Argentina was a magnitude 5.9 earthquake near Tinogasta, Argentina on 24 December 2024 at 22:42 UTC. A magnitude 5.9 earthquake radiates roughly 10,676 tons of TNT equivalent in seismic energy.

That is well above the Argentina monthly average of 9 events over the period we cover — an unusually active month, and up from the 5 recorded the previous month.

9% of events here are shallow (under 70 km), 91% 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 20 in the magnitude 4 range, 2 in the magnitude 5 range.

Activity peaked on 16 December, when 2 events were recorded.

The month's largest events were M5.9 near Tinogasta, Argentina on 24 December at 125 km; M5.2 near Municipio de Catua, Argentina on 05 December at 227 km; M4.9 near Zonda, Argentina on 18 December at 109 km.

That is 144% above the 9 events Argentina averages per month across the 2 months on record.

This month also holds the strongest earthquake recorded in Argentina in our entire catalogue.
