Earthquakes in Chile — April 2025

36 earthquakes were recorded in Chile during April 2025, an average of 1.2 per day.

33 reached magnitude 4 or above and 4 reached magnitude 5 or above. The average focal depth was 70 km.

The month's largest event in Chile was a magnitude 5.6 earthquake near San Pedro de Atacama, Chile on 18 April 2025 at 00:10 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 45 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 3 in the magnitude 3 range, 29 in the magnitude 4 range, 4 in the magnitude 5 range.

Activity peaked on 29 April, when 3 events were recorded.

The month's largest events were M5.6 near San Pedro de Atacama, Chile on 18 April at 129 km; M5.1 near Ovalle, Chile on 24 April at 27 km; M5.0 near Ollagüe, Chile on 08 April at 123 km.

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