Earthquakes in Ecuador — August 2025
3 earthquakes were recorded in Ecuador during August 2025, an average of 0.1 per day.

The month's largest event in Ecuador was a magnitude 4.9 earthquake near Esmeraldas, Ecuador on 25 August 2025 at 18:10 UTC. A magnitude 4.9 earthquake radiates roughly 338 tons of TNT equivalent in seismic energy.
That is close to the Ecuador monthly average of 3 events over the period we cover, and level with the 3 recorded the previous month.
67% of events here are shallow (under 70 km), 33% 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 4 range.
The month's largest events were M4.9 near Esmeraldas, Ecuador on 25 August at 10 km; M4.8 near Alausí, Ecuador on 24 August at 101 km; M4.6 near Machachi, Ecuador on 16 August at 10 km.
