Earthquakes in Fiji — August 2026

12 earthquakes were recorded in Fiji during August 2026, an average of 0.4 per day.

12 reached magnitude 4 or above and 3 reached magnitude 5 or above. The average focal depth was 524 km.

The month's largest event in Fiji was a magnitude 5.4 earthquake near Levuka, Fiji on 19 August 2026 at 18:45 UTC. A magnitude 5.4 earthquake radiates roughly 1,898 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 19 recorded the previous month.

8% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 92% 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 9 in the magnitude 4 range, 3 in the magnitude 5 range.

Activity peaked on 03 August, when 2 events were recorded.

The month's largest events were M5.4 near Levuka, Fiji on 19 August at 557 km; M5.1 near Levuka, Fiji on 12 August at 571 km; M5.0 near Levuka, Fiji on 17 August at 564 km.

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