Earthquakes in Chile — August 2025

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

33 reached magnitude 4 or above and 2 reached magnitude 5 or above. The average focal depth was 69 km.

The month's largest event in Chile was a magnitude 5.6 earthquake near Off the coast of Aisen, Chile on 18 August 2025 at 07:10 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 37 recorded the previous month.

56% of events here are shallow (under 70 km), 44% 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, 31 in the magnitude 4 range, 2 in the magnitude 5 range.

Activity peaked on 11 August, when 4 events were recorded.

The month's largest events were M5.6 near Off the coast of Aisen, Chile on 18 August at 10 km; M5.0 near Camiña, Chile on 24 August at 101 km; M4.9 near Ollagüe, Chile on 11 August at 142 km.

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