Earthquakes in Fiji — August 2025

12 earthquakes were recorded in Fiji during August 2025, an average of 0.4 per day.

12 reached magnitude 4 or above and 2 reached magnitude 5 or above. The average focal depth was 550 km.

The month's largest event in Fiji was a magnitude 5.6 earthquake near Levuka, Fiji on 26 August 2025 at 01:32 UTC. A magnitude 5.6 earthquake radiates roughly 3,788 tons of TNT equivalent in seismic energy.

That is close to the Fiji monthly average of 15 events over the period we cover, and down from the 24 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 10 in the magnitude 4 range, 2 in the magnitude 5 range.

Activity peaked on 05 August, when 2 events were recorded.

The month's largest events were M5.6 near Levuka, Fiji on 26 August at 589 km; M5.4 near Fiji region on 24 August at 348 km; M4.5 near Fiji region on 13 August at 409 km.

That is 17% below the 15 events Fiji averages per month across the 21 months on record.
