Earthquakes in Chile — August 2026

15 earthquakes were recorded in Chile during August 2026, an average of 0.5 per day.

15 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 92 km.

The month's largest event in Chile was a magnitude 4.7 earthquake near Diego de Almagro, Chile on 21 August 2026 at 22:26 UTC. A magnitude 4.7 earthquake radiates roughly 169 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 37 recorded the previous month.

20% of events here are shallow (under 70 km), 80% 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 15 in the magnitude 4 range.

Activity peaked on 03 August, when 2 events were recorded.

The month's largest events were M4.7 near Diego de Almagro, Chile on 21 August at 102 km; M4.7 near Antofagasta, Chile on 20 August at 35 km; M4.6 near Calama, Chile on 22 August at 105 km.

That is 55% below the 33 events Chile averages per month across the 21 months on record.
