Earthquakes in Brazil — August 2025
1 earthquakes were recorded in Brazil during August 2025, an average of 0.0 per day.
1 reached magnitude 4 or above and 1 reached magnitude 5 or above. The average focal depth was 487 km.
The month's largest event in Brazil was a magnitude 5.0 earthquake near Tarauacá, Brazil on 03 August 2025 at 11:42 UTC. A magnitude 5.0 earthquake radiates roughly 477 tons of TNT equivalent in seismic energy.
That is close to the Brazil monthly average of 1 events over the period we cover, and level with the 1 recorded the previous month.
0% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 100% deep-focus (over 300 km). That proportion of deep-focus events is the signature of a subduction zone: only a cold slab descending into the mantle stays brittle enough to rupture at those depths.
By band, the catalogue holds 1 in the magnitude 5 range.
That is close to the 1 events Brazil averages per month across the 5 months on record.
This month also holds the strongest earthquake recorded in Brazil in our entire catalogue.
