Earthquakes in Chile — December 2025

34 earthquakes were recorded in Chile during December 2025, an average of 1.1 per day.

34 reached magnitude 4 or above and 3 reached magnitude 5 or above. The average focal depth was 91 km.

The month's largest event in Chile was a magnitude 5.4 earthquake near Ollagüe, Chile on 13 December 2025 at 12:18 UTC. A magnitude 5.4 earthquake radiates roughly 1,898 tons of TNT equivalent in seismic energy.

That is close to the Chile monthly average of 33 events over the period we cover, and up from the 30 recorded the previous month.

35% of events here are shallow (under 70 km), 65% 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 31 in the magnitude 4 range, 3 in the magnitude 5 range.

Activity peaked on 03 December, when 4 events were recorded.

The month's largest events were M5.4 near Ollagüe, Chile on 13 December at 96 km; M5.2 near Vallenar, Chile on 10 December at 43 km; M5.2 near Colchane, Chile on 20 December at 156 km.

That is close to the 33 events Chile averages per month across the 21 months on record.
