Earthquakes in Chile — October 2026

17 earthquakes were recorded in Chile during October 2026, an average of 0.5 per day.

17 reached magnitude 4 or above and 3 reached magnitude 5 or above. The average focal depth was 76 km.

The month's largest event in Chile was a magnitude 5.1 earthquake near Coquimbo, Chile on 14 October 2026 at 00:30 UTC. A magnitude 5.1 earthquake radiates roughly 674 tons of TNT equivalent in seismic energy.

That is below the Chile monthly average of 33 events over the period we cover — a comparatively quiet month, and down from the 35 recorded the previous month.

47% of events here are shallow (under 70 km), 53% 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 14 in the magnitude 4 range, 3 in the magnitude 5 range.

Activity peaked on 14 October, when 4 events were recorded.

The month's largest events were M5.1 near Coquimbo, Chile on 14 October at 22 km; M5.1 near Colchane, Chile on 09 October at 124 km; M5.0 near Coquimbo, Chile on 14 October at 10 km.

That is 49% below the 33 events Chile averages per month across the 23 months on record.
