Earthquakes in Chile — October 2025

29 earthquakes were recorded in Chile during October 2025, an average of 0.9 per day.

28 reached magnitude 4 or above and 4 reached magnitude 5 or above. The average focal depth was 71 km.

The month's largest event in Chile was a magnitude 5.6 earthquake near Ovalle, Chile on 15 October 2025 at 11:43 UTC. A magnitude 5.6 earthquake radiates roughly 3,788 tons of TNT equivalent in seismic energy.

That is close to the Chile monthly average of 33 events over the period we cover, and down from the 36 recorded the previous month.

55% of events here are shallow (under 70 km), 45% 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, 24 in the magnitude 4 range, 4 in the magnitude 5 range.

Activity peaked on 13 October, when 4 events were recorded.

The month's largest events were M5.6 near Ovalle, Chile on 15 October at 32 km; M5.4 near Ovalle, Chile on 02 October at 19 km; M5.2 near Off the coast of Aisen, Chile on 25 October at 10 km.

That is 13% below the 33 events Chile averages per month across the 21 months on record.
